William Mougayar is an angel investor who has been investigating the cryptocurrency and broader distributed ledger ecosystem over the past several years.
He recently published a book that looks at how enterprises and organizations should look at distributed ledgers and specifically, blockchains.
While it is better than “Blockchain Revolution” from the Tapscott’s, it still has multiple errors and unproven conjectures that prevent me from recommending it. For instance, it does not really distinguish one blockchain from another, or the key differences between a distributed ledger and a blockchain.
Note: all transcription errors below are my own.
On p. xxii he writes:
“These are necessary but not sufficient conditions or properties; blockchains are also greater than the sum of their parts.”
I agree with this and wrote something very similar two years ago in Chapter 2:
While the underlying mathematics and cryptographic concepts took decades to develop and mature, the technical parts and mechanisms of the ledger (or blockchain) are greater than the sum of the ledger’s parts.
On p. xxiv he writes:
“Just like we cannot double spend digital money anymore (thanks to Satoshi Nakamoto’s invention), we will not be able to double copy or forge official certificates once they are certified on a blockchain.”
There are two problems with this:
Double-spending can and does still occur, each month someone posts on social media how they managed to beat a retailer/merchant that accepted zero-confirmation transactions
Double-spending can and is prevented in centralized architectures today, you don’t need a blockchain to prevent double-spending if you are willing to trust a party
[Note: recommend that future editions should include labeled diagrams/tables/figures]
On p. 11 he writes:
“Solving that problem consists in mitigating any attempts by a small number of unethical Generals who would otherwise become traitors, and lie about coordinating their attack to guarantee victory.”
It could probably be written slightly different: how do you coordinate geographically dispersed actors to solve a problem in which one or more actor could be malicious and attempt to change the plan? See also Lamport et al. explanation.
On p.13 he writes compares a database with a blockchain which he calls a “ledger.”
I don’t think this is an accurate comparison.
For instance, a ledger, as Robert Sams has noted, assumes ties to legal infrastructure. Some blockchains, such as Bitcoin, were intentionally designed not to interface with legal infrastructure, thus they may not necessarily be an actual ledger.
To quote Sams:
I think the confusion comes from thinking of cryptocurrency chains as ledgers at all. A cryptocurrency blockchain is (an attempt at) a decentralised solution to the double spending problem for a digital, extra-legal bearer asset. That’s not a ledger, that’s a log.
That was the point I was trying to make all along when I introduced the permissioned/permissionless terminology! Notice, I never used the phrase “permissionless ledger” — Permissionless’ness is a property of the consensus mechanism.
With a bearer asset, possession of some instrument (a private key in the cryptocurrency world) means ownership of the asset. With a registered asset, ownership is determined by valid entry in a registry mapping an off-chain identity to the asset. The bitcoin blockchain is a public log of proofs of instrument possession by anonymous parties. Calling this a ledger is the same as calling it “bearer asset ledger”, which is an oxymoron, like calling someone a “married bachelor”, because bearer assets by definition do not record their owners in a registry!
This taxonomy that includes the cryptocurrency stuff in our space (“a public blockchain is a permissionless distributed ledger of cryptocurrency”) causes so much pointless discussion.
I should also mention that the DLT space should really should be using the phrase “registry” instead of “ledger”. The latter is about accounts, and it is one ambition too far at the moment to speak of unifying everyone’s accounts on a distributed ledger.
Is this pedantic? Maybe not, as the authors of The Law of Bitcoin also wrestle with the buckets an anarchic cryptocurrency fall under.
On p. 14 he writes about bank accounts:
“In reality, they provided you the illusion of access and activity visibility on it. Every time you want to move money, pay someone or deposit money, the bank is giving you explicit access because you gave them implicit trust over your affairs. But that “access” is also another illusion. It is really an access to a database record that says you have such amount of money. Again, they fooled you by giving you the illusion that you “own” that money.”
This is needless inflammatory. Commercial law and bankruptcy proceedings will determine who owns what and what tranche/seniority your claims fall under. It is unclear what the illusion is.
On p. 14 he writes:
“A user can send money to another, via a special wallet, and the blockchain network does the authentication, validation and transfer, typically within 10 minutes, with or without a cryptocurrency exchange in the middle.”
Which blockchain is he talking about? If it is not digital fiat, how does the cash-in/cash-out work? To my knowledge, no bank has implemented an end-to-end production system with other banks as described above. Perhaps that will change in the future.
On p. 18 he writes:
“Sometimes it is represented by a token, which is another form of related representation of an underlying cryptocurrency.”
This isn’t very well-defined. The reason I went to great lengths in November to explain what a “token” is and isn’t is because of the confusion caused by the initial usage of a cryptographic token, a hardware device from companies like RSA. This is not what a “token” in cryptocurrency usage means. (Note: later on p. 91 he adds a very brief explanation)
On p. 18 he cites Robert Sams who is quoting Nick Szabo, but didn’t provide a source. It is found in Seigniorage Shares.
On p. 18 he also writes:
“As cryptocurrency gains more acceptance and understanding, its future will be less uncertain, resulting in a more stable and gradual adoption curve.”
This is empirically not true and actually misses the crux of Sams’ argument related to expectations.
On p. 20 he writes:
“As of 2016, the Bitcoin blockchain was far from these numbers, hovering at 5-7 TPS, but with prospects of largely exceeding it due to advances in sidechain technology and expected increases in the Bitcoin block size.”
This isn’t quite correct. On a given day over the past year, the average TPS is around 2 TPS and Tradeblock estimates by the end of 2016 that with the current block size it will hover around just over 3 TPS.
What is a sidechain? It is left undefined in that immediate section. One potential definition is that it is a sofa.
On p. 20 he writes:
“Private blockchains are even faster because they have less security requirements, and we are seeing 1,000-10,000 TPS in 2016, going up to 2,000-15,000 TPS in 2017, and potentially an unlimited ceiling beyond 2019.”
This is untrue. “Private blockchains” do not have “less” security requirements, they have different security requirements since they involve known, trusted participants. I am also unaware of any production distributed ledger system that hits 10,000 TPS. Lastly, it is unclear where the “unlimited ceiling” prediction comes from.
On p. 20 he writes:
“In 2014, I made the strong assertion that the blockchain is the new database, and warned developers to get ready to rewrite everything.”
Where did you warn people? Link?
On p. 21 he writes:
“For developers, a blockchain is first and foremost a set of software technologies.”
I would argue that it is first and foremost a network.
On p. 22 he writes:
“The fact that blockchain software is open source is a powerful feature. The more open the core of a blockchain is, the stronger the ecosystem around it will become.”
Some, but not all companies building blockchain-related technology, open source the libraries and tools. Also, this conflates the difference between code and who can validate transactions on the network. A “private blockchain” can be open sourced and secure, but only permit certain entities to validate transactions.
On p. 24 he writes:
“State machines are a good fit for implementing distributed systems that have to be fault-tolerant.”
On p. 25 he writes:
“Bitcoin initiated the Proof-of-Work (POW) consensus method, and it can be regarded as the granddaddy of these algorithms. POW rests on the popular Practical Byzantine Fault Tolerant algorithm that allows transactions to be safely committed according to a given state.”
There are at least two problems with this statement:
The proof-of-work mechanism used in Bitcoin is apocryphally linked to Hashcash from Adam Back; however this does not quite jive with Mougayar’s statement above. Historically, this type of proof-of-work predates Back’s contribution, all the way to 1992. See Pricing via Processing or Combatting Junk Mail by Dwork and Naor
“One of the drawbacks of the Proof-of-Work algorithm is that it is not environmentally friendly, because it requires large amounts of processing power from specialized machines that generate excessive energy.”
This is a design feature: to make it economically costly to change history. It wasn’t that Satoshi conjured up a consensus method to be environmentally friendly, rather it is the hashrate war and attempt to seek rents on seigniorage that incentivizes the expenditure of capital, in this case energy. If the market price of a cryptocurrency such as bitcoin declined, so too would the amount of energy used to secure it.
On p. 29 he writes:
“Reaching consensus is at the heart of a blockchain’s operations. But the blockchain does it in a decentralized way that breaks the old paradigm of centralized consensus, when one central database used to rule transaction validity.”
Which blockchain is he talking about? They are not a commodity, there are several different unique types. Furthermore, distributed consensus is an academic research field that has existed for more than two decades.
On p. 29 he writes:
“A decentralized scheme (which the blockchain is based on) transfers authority and trust to a decentralized network and enables its nodes to continuously and sequentially record their transactions on a public “block,” creating a unique” chain” – the blockchain.”
Mougayar describes the etymology of the word “blockchain” specific to Bitcoin itself.
Note: a block actually is more akin to a “batch” or “bucket” in the sense that transactions are bundled together into a bucket and then propagated. His definition of what a blockchain is is not inclusive enough in this chapter though because it is unclear what decentralization can mean (1 node, 100 nodes, 10,000 nodes?). Also, it is important to note that not all distributed ledgers are blockchains.
On p. 31 he writes:
“Credit card companies charge us 23% in interest, even when the prime rate is only at 1%”
Which credit card companies are charging 23%? Who is being charged this? Also, even if this were the case, how does a blockchain of some kind change that?
On p. 32 he writes:
“Blockchains offer truth and transparency as a base layer. But most trusted institutions do not offer transparency or truth. It will be an interesting encounter.”
This is just a broad sweeping generalization. What does truth and transparency mean here? Which blockchains? Which institutions? Cannot existing institutions build or use some kind of distributed ledger to provide the “truth” and “transparency” that he advocates?
On p. 33 he writes:
“The blockchain challenges the roles of some existing trust players and reassigns some of their responsibilities, sometimes weakening their authority.”
Typo: should be “trusted” not “trust.”
On p. 34 he writes:
“There is a lesson from Airbnb, which has mastered the art of allowing strangers to sleep in your house without fear.”
This is not true, there are many examples of Airbnb houses that have been trashed and vandalized.
On p. 34, just as the Tapscott’s did in their book, Mougayar talks about how Airbnb could use a blockchain for identity and reputation. Sure, but what are the advantages of doing that versus a database or other existing technology?
On p. 37 he writes:
“Enterprises are the ones asking, because the benefits are not necessarily obvious to them. For large companies, the blockchain presented itself as a headache initially. It was something they had not planned for.”
First off, which blockchain? And which enterprises had a headache from it?
On p. 39 he writes: “Prior to the Bitcoin invention…”
He should probably flip that to read “the invention of Bitcoin”
On p. 40 he writes:
“… it did not make sense to have money as a digital asset, because the double-spend (or double-send) problem was not solved yet, which meant that fraud could have dominated.”
This is empirically untrue. Centralized systems prevent double-spending each and every day. There is a double-spending problem when you are using a pseudonymous, decentralized network and it is partially resolved (but not permanently solved) in Bitcoin by making it expensive, but not impossible, to double-spend.
On p. 41 he writes:
“They will be no less revolutionary than the invention of the HTML markup language that allowed information o be openly published and linked on the Web.”
This is a little redundant and should probably be rewritten as “the invention of the hypertext markup language (HTML).”
On p. 43 he writes:
“Smart contracts are ideal for interacting with real-world assets, smart property, Internet of Things (IoT) and financial services instruments.”
Why are smart contracts ideal for that?
On p. 46 he writes: “Time-stamping” and in other areas he writes it without a dash.
On p. 46 he writes:
“And blockchains are typically censorship resistant, due to the decentralized nature of data storage, encryption, and peer controls at the edge of the network.”
Which blockchains? Not all blockchains in the market are censorship resistant. Why and why not?
On p. 48 he mentions “BitIID” – this is a typo for “BitID”
On p. 51 he writes:
“Enter the blockchain and decentralized applications based on it. Their advent brings potential solutions to data security because cryptographically-secured encryption becomes a standard part of blockchain applications, especially pertaining to the data parts. By default, everything is encrypted.”
This is untrue. Bitcoin does not encrypt anything nor does Ethereum. A user could encrypt data first, take a hash of it and then send that hash to a mining pool to be added to a block, but the network itself provides no encryption ability.
On p. 52 he writes:
“Consensus in public blockchains is done publicly, and is theoretically subject to the proverbial Sybil attacks (although it has not happened yet).”
Actually, it has on altcoins. One notable occurrence impacted Feathercoin during June 2013.
On p. 54 he writes:
“The blockchain can help, because too many Web companies centralized and hijacked what could have been a more decentralized set of services.”
This is the same meme in the Tapscott book. There are many reasons for why specific companies and organizations have large users bases but it is hard to see how they hijacked anyone; but that is a different conversation altogether.
On p. 54 he writes:
“We can also think of blockchains as shared infrastructure that is like a utility. If you think about how the current Internet infrastructure is being paid for, we subsidize it by paying monthly fees to Internet service providers. As public blockchains proliferate and we start running millions of smart contacts and verification services on them, we might be also subsidizing their operation, by paying via micro transactions, in the form of transaction fees, smart contract tolls, donation buttons, or pay-per-use schemes.”
This is a very liberal use of the word subsidize. What Mougayar is describing above is actually more of a tax than a charitable donation.
The design behind Bitcoin was intended to make it such that there was a Nash equilibrium model between various actors. That miners would not need to rely on charity to continue to secure the network because as block rewards decline, the fees themselves would in the long run provide enough compensation to pay for their security services.
It could be argued that this will not happen, that fees will not increase to offset the decline in block rewards but that is for a different article.
As an aside, Mougayar’s statement above then intersects with public policy: which blockchains should receive that subsidy or donation? All altcoins too? And who should pay this?
“Blockchains are like a virtual computer somewhere in a distributed cloud that is virtual and does not require server setups. Whoever opens a blockchain node runs the server, but not users or developers.”
This is untrue. The ~6,400 nodes on the Bitcoin network are all servers that require setup and maintenance to run. The same for Ethereum and any other blockchain.
On p. 58 he writes:
“It is almost unimaginable to think that when Satoshi Nakamoto released the code for the first Bitcoin blockchain in 2009, it consisted of just two computers and a token.”
A couple issues:
There is a typo – “first” should be removed (unless there was another Bitcoin network before Bitcoin?)
Timo Hanke and Sergio Lerner have hypothesized that Satoshi probably used multiple computers, perhaps more than a dozen.
On p. 58 he writes:
“One of the primary differences between a public and private blockchain is that public blockchains typically have a generic purpose and are generally cheaper to use, whereas private blockchains have a more specific usage, and they are more expensive to set up because the cost is born by fewer owners.”
This is not true. From a capital and operation expenditure perspective, public blockchains are several orders of magnitude more expensive to own and maintain than a private blockchain. Why? Because there is no proof-of-work involved and therefore private blockchain operators do not need to spend $400 million a year, which is roughly the cost of maintaining the Bitcoin network today.
In contrast, depending on how a private blockchain (or distributed ledger) is set up, it could simply be run by a handful of nodes on several different cloud providers – a marginal cost.
On p. 68 he writes:
“Taken as an extreme case, just about any software application could be rewritten with some blockchain and decentralization flavor into it, but that does not mean it’s a good idea to do so.”
Yes, fully agreed!
On p. 68 he writes:
“By mid-2016, there were approximately 5,000 developers dedicated to writing software for cryptocurrency, Bitcoin or blockchains in general. Perhaps another 20,000 had dabbled with some of that technology, or written front-end applications that connect to a blockchain, one way or the other.”
Mougayar cites his survey of the landscape for this.
I would dispute this though, it’s probably an order of magnitude less.
The only way this number is 5,000 is if you liberally count attendees at meetups or all the various altcoins people have touched over the year, and so forth. Even the headcount of all the VC funded “bitcoin and blockchain” companies is probably not even 5,000 as of May 2016.
On p. 71 he writes:
“Scaling blockchains will not be different than the way we have continued to scale the Internet, conceptually speaking. There are plenty of smart engineers, scientists, researchers, and designers who are up to the challenge and will tackle it.”
This is a little too hand-wavy. One of the top topics that invariably any conversation dovetails into at technical working groups continues to be “how to scale” while keeping privacy requirements and non-functional requirements intact. Perhaps this will be resolved, but it cannot be assumed that it will be.
On p. 72 he writes:
“Large organizations, especially banks, have not been particularly interested in adopting public blockchains for their internal needs, citing potential security issues. The technical argument against the full security of public blockchains can easily be made the minute you introduce a shadow of a doubt on a potential scenario that might wreak havoc with the finality of a transaction. That alone is enough fear to form a deterring factor for staying away from public blockchain, although the argument could be made in favor of their security.”
This is a confusing passage. The bottom line is that public blockchains were not designed with the specific requirements that regulated financial institutions have. If they did, perhaps they would be used. But in order to modify a public blockchain to provide those features and characteristics, it would be akin to turning an aircraft carrier into a submarine. Sure it might be possible, but it would just be easier and safer to build a submarine instead.
Also, why would an organization use a public blockchain for their internal needs? What does that mean?
On p. 78 he writes:
“Targeting Bitcoin primarily, several governments did not feel comfortable with a currency that was not backed by a sovereign country’s institutions.”
Actually, what made law enforcement and regulators uncomfortable was a lack of compliance for existing AML/KYC regulations. The headlines and hearings in 2011-2013 revolved around illicit activities that could be accomplished as there were no tools or ability to link on-chain activity with real world identities.
On p. 87 he writes:
“The reality is that customers are not going to the branch as often (or at all), and they are not licking as many stamps to pay their bills. Meanwhile, FinTech growth is happening: it was a total response to banks’ lack of radical innovation.”
There are a couple issues going on here.
Banks have had to cut back on all spending due to cost cutting efforts as a whole and because their spending has had to go towards building reporting and compliance systems, neither of which has been categorized as “radical innovation.”
Also, to be balanced, manyh of the promises around “fintech” innovation still has yet to germinate due to the fact that many of the startups involved eventually need to incorporate and create the same cost structures that banks previously had to have. See for instance, financial controls in marketplace lending – specifically Lending Club.
On p. 88 he writes:
“If you talk to any banker in the world, they will admit that ApplePay and PayPal are vexing examples of competition that simply eats into their margins, and they could not prevent their onslaught.”
Any banker will say that? While a couple of business lines may change, which banks are being displaced by either of those two services right now?
On p. 89 he writes:
“Blockchains will not signal the end of banks, but innovation must permeate faster than the Internet did in 1995-2000.”
Why? Why must it permeate faster? What does that even mean?
On p. 89 he writes:
“This is a tricky question, because Bitcoin’s philosophy is about decentralization, whereas a bank is everything about centrally managed relationships.”
What does this mean? If anything, the Bitcoin economy is even more concentrated than the global banking world, with only about a dozen exchanges globally that handle virtually all of the trading volume of all cryptocurrencies.
On p. 89 he writes:
“A local cryptocurrency wallet skirts some of the legalities that existing banks and bank look-alikes (cryptocurrency exchanges) need to adhere to, but without breaking any laws. You take “your bank” with you wherever you travel, and as long as that wallet has local onramps and bridges into the non-cryptocurrency terrestrial world, then you have a version of a global bank in your pocket.”
This is untrue. There are many local and international laws that have been and continue to be broken involving money transmission, AML/KYC compliance and taxes. Ignoring those though, fundamentally there are probably more claims on bitcoins – due to encumbrances – than bitcoins themselves. This is a big problem that still hasn’t been dealt with as of May 2016.
On p. 95 he writes:
“The decentralization of banking is here. It just has not been evenly distributed yet.”
This is probably inspired by William Gibson who said: ‘The future is already here — it’s just not very evenly distributed.’
On p. 95 he writes:
“The default state and starting position for innovation is to be permissionless. Consequently, permissioned and private blockchain implementations will have a muted innovation potential. At least in the true sense of the word, not for technical reasons, but for regulatory ones, because these two aspect are tie together.”
This is not a priori true, how can he claim this? Empirically we know that permissioned blockchains are designed for different environments than something like Bitcoin. How can he measure the amount of potential “innovation” either one has?
On p. 95 he writes:
“We are seeing the first such case unfold within the financial services sector, that seems to be embracing the blockchain fully; but they are embracing it according to their own interpretation of it, which is to make it live within the regulatory constraints they have to live with. What they are really talking about is “applying innovation,” and not creating it. So, the end-result will be a dialed down version of innovation.”
This is effectively an ad hominem attack on those working with regulated institutions who do not have the luxury of being able to ignore laws and regulations in multiple jurisdictions. There are large fines and even jail time for ignoring or failing to comply with certain regulations.
On p. 95 he writes:
“That is a fact, and I am calling this situation the “Being Regulated Dilemma,” a pun on the innovator’s dilemma. Like the innovator’s dilemma, regulated companies have a tough time extricating themselves from the current regulations they have to operate within. So, when they see technology, all they can do is to implement it within the satisfaction zones of regulators. Despite the blockchain’s revolutionary prognosis, the banks cannot outdo themselves, so they risk only guiding the blockchain to live within their constrained, regulated world.”
“It is a lot easier to start innovating outside the regulatory boxes, both figuratively and explicitly. Few banks will do this because it is more difficult.”
“Simon Taylor, head of the blockchain innovation group at Barclays, sums it up: “I do not disagree the best use cases will be outside regulated financial services. Much like the best users of cloud and big data are not the incumbent blue chip organizations. Still their curioisity is valuable for funding and driving forward the entire space.” I strongly agree; there is hope some banks will contribute to the innovation potential of the blockchain in significant ways as they mature their understanding and experiences with this next technology.
An ending note to banks is that radical innovation can be a competitive advantage, but only if it is seen that way. Otherwise innovation will be dialed down to fit their own reality, which is typically painted in restrictive colors.
It would be useful to see banks succeed with the blockchain, but they need to push themselves further in terms of understanding what the blockchain can do. They need to figure out how they will serve their customers better, and not just how they will serve themselves better. Banks should innovate more by dreaming up use cases that we have not though about yet, preferably in the non-obvious category.
The fundamental problem with his statement is this: banks are heavily regulated, they cannot simply ignore the regulations because someone says they should. If they fail to maintain compliance, they can be fined.
But that doesn’t mean they cannot still be innovative, or that the technology they are investigating now isn’t useful or helpful to their business lines.
In effect, this statement is divorced from the reality that regulated financial institutions operate in. [Note: some of his content such as the diagram originated from his blog post]
On p. 102 he writes:
“Banks will be required to apply rigorous thinking to flush out their plans and positions vis-à-vis each one of these major blockchain parameters. They cannot ignore what happens when their core is being threatened.”
While this could be true, it is an over generalization: what type of business lines at banks are being threatened? What part of “their” core is under attack?
On p. 103 he writes:
“More than 200 regulatory bodies exist in 150 countries, and many of them have been eyeing the blockchain and pondering regulatory updates pertaining to it.”
Surely that is a typo, there are probably 200 regulatory bodies alone in the US itself.
On p. 105 he writes:
“Banks will need to decide if they see the blockchain as a series of Band-Aids, or if they are willing to find the new patches of opportunity. That is why I have been advocating that they should embrace (or buy) the new cryptocurrency exchanges, not because these enable Bitcoin trades, but because they are a new generation of financial networks that has figured out how to transfer assets, financial instruments, or digital assets swiftly and reliably, in essence circumventing the network towers and expense bridges that the current financial services industry relies upon.”
This is a confusing passage.
Nearly all of the popular cryptocurrency exchanges in developed countries require KYC/AML compliance in order for users to cash-in and out of their fiat holdings. How do cryptocurrency exchanges provide any utility to banks who are already used to transferring and trading foreign exchange?
In terms of percentages, cryptocurrency exchanges are still very easy to compromise versus banks; what utility do banks obtain by acquiring exchanges with poor financial controls?
And, in order to fund their internal operations, cryptocurrency exchanges invariably end up with the same type of cost structures regulated financial institutions have; the advantage that they once had effectively involved non-compliance – that is where some of the cost savings was. And banks cannot simply ignore regulations because people on social media want them to; these cryptocurrency sites require money to operate, hence the reason why many of them charge transaction fees on all withdrawals and some trades.
On p. 115 he mentions La’Zooz and Maidsafe, neither of which – after several years of development, actually work. Perhaps that changes in the future.
On p.118 he writes:
“There is another potential application of DIY Government 2.0. Suppose a country’s real government is failing, concerned citizens could create a shadow blockchain governance that is more fair, decentralized and accountable. There are at least 50 failed, fragile, or corrupt states that could benefit from an improve blockchain governance.”
Perhaps this is true, that there could be utility gain from some kind of blockchain. But this misses a larger challenge: many of these same countries lack private property rights, the rule of law and speedy courts.
On p. 119 he writes about healthcare use cases:
“Carrying a secure wallet with our full electronic medical record in it, or our stored DNA, and allowing its access, in case of emergency.”
What advantage do customers gain from carrying this around in a secure wallet? Perhaps they do, but it isn’t clear in this chapter.
On p. 126-127 he makes the case for organizations to have a “blockchain czar” but an alternative way to pitch this without all the pomp is simply to have someone be tasked with becoming a subject-matter expert on the topic.
On p. 131 he writes:
“Transactions are actually recorded in sequential data blocks (hence the word blockchain), so there is a historical, append-only log of these transaction that is continuously maintained and updated. A fallacy is that the blockchain is a distributed ledger.”
It is not a fallacy.
On p. 149 he writes: “What happened to the Web being a public good?”
Costs. Websites have real costs. Content on those websites have real costs. And so forth. Public goods are hard to sustain because no one wants to pay for them but everyone wants to use them. Eventually commercial entities found a way to build and maintain websites that did not involve external subsidization.
On p. 150 he writes:
“Indeed, not only was the Web hijacked with too many central choke points, regulators supposedly continue to centralize controls in order to lower risk, whereas the opposite should be done.”
This conflicts with the “Internet is decentralized” meme that was discussed throughout the book. So if aspects of the Internet are regulated, and Mougayar disagrees with those regulations, doesn’t this come down to disagreements over public policy?
On p. 153 he writes:
“Money is a form of value. But not all value is money. We could argue that value has higher hierarchy than money. In the digital realm, a cryptocurrency is the perfect digital money. The blockchain is a perfect exchange platform for digital value, and it rides on the Internet, the largest connected network on the planet.”
Why are cryptocurrencies perfect? Perhaps they are, but it is not discussed here.
On p. 153 he also talks about the “programmability” of cryptocurrencies but doesn’t mention that if fiat currencies were digitally issued by central banks, they too could have the same programmable abilities.
On p. 160 he predicts:
“There will be dozens of commonly used, global virtual currencies that will be considered mainstream, and their total market value will exceed $5 trillion, and represent 5% of the world’s $100 trillion economy in 2025.”
Perhaps that occurs, but why? And are virtual currencies now different than digital currencies? Or are they the same? None of these questions are really addressed.
This book is quick read but unfortunately is weighed down by many opinions that are not supported by evidence and consequently, very few practical applications for enterprises are explained in detail.
For regulated businesses such as financial institutions, there are several questions that need to be answered such as: what are the specific cost savings for using or integrating with some kind of blockchain? What are the specific new business lines that could be created? And unfortunately the first edition of this book did not answer these types of questions. Let us look again at a future version.
[Disclaimer: The views expressed below are solely my own and do not necessarily represent the views of my employer or any organization I advise.]
A couple weeks ago I joked that while containment is impossible, it would be nice to know who patient-zero was for using the term “blockchain” without an article preceding it. The mystery of who exactly removed the “a” before “blockchain” is probably residing on the same island that Yeti, Sasquatch, and the New England Patriot’s equipment team are now located.
The Tapscott’s, a Canada-based father-son duo, co-authored a new book that not only suffers from this grammatical faux pas but has several dozen errors and unproven assertions which are detailed in this review.
Below is a chapter-by-chapter look into a book that should have baked in the oven for a bit more time. Note: all transcription errors are my own.
On p. 5 the authors write:
“A decade later in 2009, the global financial industry crashed. Perhaps propitiously, a pseudonymous person or persons named Satoshi Nakamoto outlined a new protocol for a peer-to-peer electronic cash system using a cryptocurrency called bitcoin.”
Ignoring the current drama surrounding Craig Wright — the Australian who claims to be Satoshi — during the initialthreads on Metzdowd, Satoshi mentioned he had been working on this project for 18 months prior; roughly mid-2007. So it was more coincidental timing than intentional.
And much like other books on the same topic, the authors do not clarify that there are more than one type of blockchain in existence and that some are a type of distributed ledger.
For instance, on p. 6 they write:
“At its most basic, it is an open source code: anyone can download it for free, run it, and use it to develop new tools for managing transactions online.”
With the ‘it’ being a ‘blockchain.’ The problem with this grammatical issue is that we know empirically that there many different types of distributed ledgers and blockchains currently under development and not all of them are open sourced. Nor does being open source automagically qualify something as a blockchain.
On p. 6 they write:
“However, the most important and far-reaching blockchains are based on Satoshi’s bitcoin model.”
That’s an opinion that the authors really don’t back up with facts later on.
In addition, on the same page they make the “encryption” error that also plagues books in this space: the Bitcoin blockchain does not use encryption.
For example, on page 6 they write:
“And the blockchain is encrypted: it uses heavy-duty encryption involving public and private keys (rather like the two-key system to access a safety deposit box) to maintain virtual security.”
Incorrect. Bitcoin employs a couple different cryptographic processes, but it doesn’t use encryption. Furthermore, the example of a ‘two-key system’ actually illustrates multisig, not public-private key pairs.
On p. 8 they write:
“Bankers love the idea of secure, frictionless, and instant transactions, but some flinch at the idea of openness, decentralization and new forms of currency. The financial services industry has already rebranded and privatized blockchain technology, referring to it as distributed ledger technology, in an attempt to reconcile the best of bitcoin — security, speed, and cost — with an entirely closed system that requires a bank or financial institution’s permission to use.”
There is a lot of assumptions in here:
(1) it is unclear which “bankers” they are speaking about, is it every person who works at a bank?
(2) the term ‘openness’ is not very well defined, does that mean that people at banks do not want to have cryptographically proven provenance?
In addition, in order for something to be privatized it must have been public at first. Claiming that the “blockchain” toolkit of ideas and libraries was privatized away from Bitcoin is misleading. The moving pieces of Bitcoin itself are comprised of no less than 6 discrete elements that previously existed in the cryptography and distributed systems communities.
The Bitcoin network itself is not being privatized by financial institutions. In fact, if anything, empirically Bitcoin itself is being carved away by entities and efforts largely financed by venture capital — but that is a topic for another article. Furthermore, research into distributed computing and distributed consensus techniques long predates Bitcoin itself, by more than a decade.
Lastly, and this is why it helps to clearly define words at the beginning of a book, it is important to note that some blockchains are a type of distributed ledger but not all distributed ledgers are blockchains.
On page 9 they write that:
“In 2014 and 2015 alone more than $1 billion of venture capital flooded into the emerging blockchain ecosystem, and the rate of investment is almost doubling annually.”
This is only true if you conflate cryptocurrency systems with non-cryptocurrency systems. The two are separate and have completely different business models. See my December presentation for more details about the divergence.
On p. 9 they write:
“A 2013 study showed that 937 people owned half of all bitcoin, although that is changing today.”
First off, this is a typo because the original article the authors cite, actually says the number is 927 not 937. And the ‘study’ showed that about half of all bitcoins resided on addresses controlled by 937 on-chain entities. Addresses does not mean individuals. It is likely that some of these addresses (or rather, UTXOs) are controlled and operated by early adopters (like Roger Ver) as well as exchanges (like Bitstamp and Coinbase).
Furthermore, it is unclear from the rest of the book how that concentration of wealth is changing — where is that data?
On p. 18 they write about Airbnb, but with a blockchain. It is unclear from their explanation what the technical advantage is of using a blockchain versus a database or other existing technology.
On p. 20 they write:
“Abra and other companies are building payment networks using the blockchain. Abra’s goal is to turn every one of its users into a teller. The whole process — from the funds leaving one country to their arriving in another — takes an hour rather than a week and costs 2 percent versus 7 percent or higher. Abra wants its payment network to outnumber all physical ATMs in the world. It took Western Union 150 years to get to 500,000 agents worldwide. Abra will have that many tellers in its first years.”
There are at least 3 problems with this statement:
the authors conflate a blockchain with all blockchains; empirically there is no “the” blockchain
Abra’s sales pitch relies on the ability to convince regulators that the company itself just make software and doesn’t participate in money transmission or movement of financial products (which it does by hedging)
Fast forward to May 2016 and according to the Google Play Store and Abra has only been downloaded about 5,000 times.
Perhaps it will eventually reach 500,000 and even displace Western Union, but the authors’ predictions that this will occur in one year is probably not going to happen at the current rate.
Furthermore, on p. 186 they write that “Abra takes a 25-basis-point fee on conversion.”
Will this require a payment processing license in each jurisdiction the conversion takes place?
On page 24 they write:
“Other critics point to the massive amount of energy consumed to reach consensus in just the bitcoin network: What happens when thousands or perhaps millions of interconnected blockchains are each processing billions of transactions a day? Are the incentives great enough for people to participate and behave safely over time, and not try to overpower the network? Is blockchain technology the worst job killer ever?”
There are multiple problems with this statement:
on a proof-of-work blockchain, the amount of energy consumed is notconnected with the amount of transactions being processed. Miners consume energy to generate proofs-of-work irrespective of the number of transactions waiting in the memory pool. Transaction processing itself is handled by a different entity entirely called a block maker or mining pool.
as of May 2016, it is unclear why there would be millions of interconnected proof-of-work blockchains. There are perhaps a couple hundred altcoins, at least 100 of which are dead, but privately run blockchains do not need to use proof-of-work — thus the question surrounding incentives is a non sequitur.
while blockchains however defined may displace workers of some kind at some point, the authors never really zero in on what “job killing” blockchains actually do?
On p. 25 they write:
“The blockchain and cryptocurrencies, particularly bitcoin, already have massive momentum, but we’re not predicting whether or not all this will succeed, and if it does, how fast it will occur.”
Nowhere do the authors actually cite empirical data showing traction. If there was indeed massive momentum, we should be able to see that from data somewhere, but so far that is not happening. Perhaps that changes in the future.
The closing paragraph of Chapter 1 states that:
“Everyone should stop fighting it and take the right steps to get on board. Let’s harness this force not for the immediate benefit of the few but for the lasting benefit of the many.”
Who is fighting what? They are presumably talking about a blockchain, but which one? And why should people stop what they are doing to get on board with something that is ill-defined?
On p. 30 they write that:
“Satoshi leveraged an existing distributed peer-to-peer network and a bit of clever cryptography to create a consensus mechanism that could solve the double-spend problem as well as, if not better than, a trusted third party.”
The word “trust” or variation thereof appears 11 times in the main body of the original Satoshi whitepaper. Routing around trusted third parties was the aim of the project as this would then allow for pseudonymous interaction. That was in October 2008.
What we empirically see in 2016 though is an increasingly doxxed environment in which it could be argued that ‘trusted’ parties could do the same job — movement of payments — in a less expensive manner. But that is a topic for another article.
On p. 33 they write:
“So important are the processes of mining — assembling a block of transactions, spending some resource, solving the problem, reaching consensus, maintaining a copy of the full ledger — that some have called the bitcoin blockchain a public utility like the Internet, a utility that requires public support. Paul Brody of Ernst & Young thinks that all our appliances should donate their processing power to upkeep of a blockchain: “Your lawnmower or dishwasher is going to come with a CPU that is probably a thousand times more powerful than it actually needs, and so why not have it mine? Not for the purpose of making you money, but to maintain your share of the blockchain,” he said. Regardless of the consensus mechanism, the blockchain ensures integrity through clever code rather than through human beings who choose to do the right thing.”
Let’s dissect this:
the process of mining, as we have looked at before, involves a division of labor between the entities that generate proofs-of-work – colloquially referred to as miners, and those that package transactions into blocks, called blockmakers. Miners themselves do not actually maintain a copy of a blockchain, pools do.
while public blockchains like Bitcoin are a ‘public good,’ it doesn’t follow how or why anyone should be compelled to subsidize them, at least the reasons why are not revealed to readers.
the only reason proof-of-work was used for Bitcoin is because it was a way to prevent Sybil attacks on the network because participants were unknown and untrusted. Why should a washing machine vendor integrate an expensive chip to do calculations that do not help in the washing process? See Appendix B for why they shouldn’t.
because proof-of-work is used in a public blockchain and public blockchains are a public good, how does anyone actually have a “share” of a blockchain? What does that legally mean?
On p. 34 they write:
“The blockchain resides everywhere. Volunteers maintain it by keeping their copy of the blockchain up to date and lending their spare computer processing units for mining. No backdoor dealing.”
There are multiple problems with this:
to some degree entities that run a fully validating node could be seen as volunteering for a charity, but most do not lend spare computer cycles because they do not have the proper equipment to do so (ASIC hardware)
to my knowledge, none of the professional mining farms that exist have stated they are donating or lending their mining power; instead they calculate the costs to generate proofs-of-work versus what the market value of a bitcoin is worth and entering and exiting the market based on the result.
this is a contentious issue, but because of the concentration and centralization of both mining and development work, there have been multiple non-public events in which mining pools, mining farms and developers get together to discuss roadmaps and policy. Is that backdoor dealing?
On p. 35 they write:
“Nothing passes through a central third party; nothing is stored on a central server.”
This may have been true a few years ago, but only superficially true today. Most mining pools connect to the Bitcoin Relay Network, a centralized network that allows miners to propagate blocks faster than they would if they used the decentralized network itself to do so (it lowers the amount of orphan blocks).
On p. 37 they write:
“The paradox of these consensus schemes is that by acting in one’s self-interest, one is serving the peer-to-peer (P2P) network, and that in turn affects one’s reputation as a member of the economic set.”
Regarding cryptocurrencies, there is currently no built-in mechanism for tracking or maintaining reputation on their internal P2P network. There are projects like OpenBazaar which are trying to do this, but an on-chain Bitcoin user does not have a reputation because there is no linkage real world identity (on purpose).
On p. 38 they write:
“Trolls need not apply”
Counterfactually, there are many trolls in the overall blockchain-related world, especially on social media in part because there is no identity system that links pseudonymous entities to real world, legal identities.
On p. 39 the authors list a number of high profile data breaches and identity thefts that took place over the past year, but do not mention the amount of breaches and thefts that take place in the cryptocurrency world each year.
On p. 41 they write:
“Past schemes failed because they lacked incentive, and people never appreciated privacy as incentive enough to secure those systems,” Andreas Antonopoulos said. The bitcoin blockchain solves nearly all these problem by providing the incentive for wide adoption of PKI for all transaction of value, not only through the use of bitcoin but also in the shared bitcoin protocols. We needn’t worry about weak firewalls, thieving employees, or insurance hackers. If we’re both using bitcoin, if we can store and exchange bitcoin securely, then we can store and exchange highly confidential information and digital assets securely on the blockchain.”
There are multiple problems with this statement:
it is overly broad and sweeping to say that every past PKI system has not only failed, but that they all failed because of incentives; neither is empirically true
Bitcoin does not solve for connecting real world legal identities that still will exist with our without the existence of Bitcoin
there are many other ways to securely transmit information and digital assets that does not involve the use of Bitcoin; and the Bitcoin ecosystem itself is still plagued by thieving employees and hackers
On p. 41 they write:
“Hill, who works with cryptographer Adam Back at Blockstream, expressed concern over cryptocurrencies that don’t use proof of work. “I don’t think proof of stake ultimately works. To me, it’s a system where the rich get richer, where people who have tokens get to decide what the consensus is, whereas proof of works ultimately is a system rooted in physics. I really like that because it’s very similar to the system for gold.”
There are multiple problems with this as well:
people that own bitcoins typically try to decide what the social consensus of Bitcoin is — by holding conferences and meetings in order to decide what the roadmap should or should not be and who should and should not be administrators
the debate over whether or not a gold-based economy is good or not is a topic that is probably settled, but either way, it is probably irrelevant to creating Sybil resistance.
On p. 42 they write:
“Satoshi installed no identity requirement for the network layer itself, meaning that no one had to provide a name, e-mail address, or any other personal data in order to download and use the bitcoin software. The blockchain doesn’t need to know who anybody is.”
The authors again conflate the Bitcoin blockchain with all blockchains in general:
there are projects underway that integrate a legal identity and KYC-layer into customized distributed ledgers including one literally called KYC-Chain (not an endorsement)
empirically public blockchains like Bitcoin have trended towards being able to trace and track asset movement back to legal entities; there are a decreasing amount of non-KYC’ed methods to enter and exit the network
On p. 43 they write:
“The blockchain offers a platform for doing some very flexible forms of selective and anonymous attestation. Austin Hill likened it to the Internet. “A TCP/IP address is not identified to a public ID. The network layer itself doesn’t know. Anyone can join the Internet, get an IP address, and start sending and receiving packets freely around the world. As a society, we’ve seen an incredible benefit allowing that level of pseudonymity… Bitcoin operates almost exactly like this. The network itself does not enforce identity. That’s a good thing for society and for proper network design.”
This is problematic in a few areas:
it is empirically untrue that anyone can just “join the Internet” because the Internet is just an amalgamation of intranets (ISPs) that connect to one another via peering agreements. These ISPs can and do obtain KYC information and routinely kick people off for violating terms of service. ISPs also work with law enforcement to link IP addresses with legal identities; in fact on the next page the authors note that as well.
in order to use the Bitcoin network a user must obtain bitcoins somehow, almost always — as of 2016 — through some KYC’ed manner. Furthermore, there are multiple projects to integrate identity into distributed ledger networks today. Perhaps they won’t be adopted, but regulated institutions are looking for ways to streamline the KYC/AML process and baking in identity is something many of them are looking at.
On p. 44 they write:
“So governments can subpoena ISPs and exchanges for this type of user data. But they can’t subpoena the blockchain.”
That is not quite true. There are about 10 companies that provide data analytics to law enforcement in order to track down illicit activity involving cryptocurrencies all the way to coin generation itself.
Furthermore, companies like Coinbase and Circle are routinely subpoenaed by law enforcement. So while the network itself cannot be physically subpoenaed, there are many other entities in the ecosystem that can be.
On p. 46 they write:
“Combined with PKI, the blockchain not only prevents a double spend but also confirms ownership of every coin in circulation, and each transaction is immutable and irrevocable.”
The public-private key technology being used in Bitcoin does not confirm ownership, only control. Ownership implies property rights and a legal system, neither of which currently exist in the anarchic world of Bitcoin.
Furthermore, while it is not currently possible to reverse the hashes (hence the immutability characteristic), blocks can and have been reorganized which makes the Bitcoin blockchain itself revocable.
On p. 47 they write:
“No central authority or third party can revoke it, no one can override the consensus of the network. That’s a new concept in both law and finance. The bitcoin system provides a very high degree of certainty as to the outcome of a contract.”
This is empirically untrue: CLS and national real-time gross settlement (RTGS) systems are typically non-reversible. And the usage of the word contract here implies some legal standing, which does not exist in Bitcoin; there is currently no bridge between contracts issued on a public blockchain with that of real world.
On p. 50 they write:
“That was part of Satoshi’s vision. He understood that, for people in developing economies, the situation was worse. When corrupt or incompetent bureaucrats in failed states need funding to run the government, their central banks and treasuries simply print more currency and then profit from the difference between the cost of manufacturing and the face value of the currency. That’s seigniorage. The increase in the money supply debases the currency.”
First off, they provide no evidence that Satoshi was actually concerned about developing countries and their residents. In addition, they mix up the difference between seigniorage and inflation – they are not the same thing.
In fact, to illustrate with Bitcoin: seigniorage is the marginal value of a bitcoin versus the marginal cost of creating that bitcoin. As a consequence, miners effectively bid up such that in the long run the cost equals the value; although some miners have larger margins than others. In contrast, the increase in the money supply (inflation) for Bitcoin tapers off every four years. The inflation or deflation rate is fully independent of the seigniorage.
On p. 56 they quote Erik Vorhees who says:
“It is faster to mail an anvil to China than it is to send money through the banking system to China. That’s crazy! Money is already digital, it’s not like they’re shipping palletes of cash when you do a wire.”
This is empirically untrue, according to SaveOnSend.com a user could send $1,000 from the US to China in 24 hours using TransFast. In addition:
today most money in developed countries is electronic, not digital; there is no central bank digital cash yet
if new distributed ledgers are built connecting financial institutions, not only could cross-border payments be done during the same day, but it could also involve actual digital cash
On p. 59 they write:
“Other blockchain networks are even faster, and new innovations such as the Bitcoin Lightning Network, aim to dramatically scale the capacity of the bitcoin blockchain while dropping settlement and clearing times to a fraction of a second.”
This is problematic in that it is never defined what clearing and settlement means. And, the Bitcoin network can only — at most — provide some type of probabilistic settlement for bitcoins and no other asset.
On p. 67 they write:
“Private blockchains also prevent the network effects that enable a technology to scale rapidly. Intentionally limiting certain freedoms by creating new rules can inhibit neutrality. Finally, with no open value innovation, the technology is more likely to stagnate and become vulnerable.”
Not all private blockchains or distributed ledgers are the same, nor do they all have the same terms of service. The common theme has to do with knowing all the participants involved in a transaction (KYC/KYCC) and only certain known entities can validate a transaction.
Furthermore, the authors do not provide any supporting evidence for why this technology will stagnate or become vulnerable.
On p. 70 they write:
“The financial utility of the future could be a walled and well-groomed garden, harvested by a cabal of influential stakeholders, or it could be an organic and spacious ecosystem, where people’s economic fortunes grow wherever there is light. The debate rages on, but if the experience of the first generation of the Internet has taught us anything, it’s that open systems scale more easily than closed ones.”
The authors do not really define what open and closed means here. Fulfilling KYC requirements through terms of service at ISPs and governance structures like ICANN did not prevent the Internet from coming into existence. It is possible to have vibrant innovation on top of platforms that require linkage to legal identification.
On p. 72 the authors quote Stephen Pair stating:
“Not only can you issue these assets on the blockchain, but you can create systems where I can have an instantaneous atomic transaction where I might have Apple stock in my wallet and I want to buy something or you. But you want dollars. With this platform I can enter a single atomic transaction (i.e., all or none) and use my Apple stock to send you dollars.”
This is currently not possible with Bitcoin without changing the legal system. Furthermore:
this is probably not safe to do with Bitcoin due to how colored coin schemes distort the mining incentive scheme
from a technological point of view, there is nothing inherently unique about Bitcoin that would enable this type of atomic swapping that several other technology platforms could do as well
On p. 73 they write:
“Not so easy. Banks, despite their enthusiasms for blockchain, have been wary of these companies, arguing blockchain businesses are “high-risk” merchants.”
Once again this shows how the authors conflate “blockchain” with “Bitcoin.” The passage they spoke about Circle, a custodian of bitcoins that has tried to find banks to partner with for exchanging fiat to bitcoins and vice versa. This is money transfer. This type of activity is different than what a “blockchain” company does, most of whom aren’t exchanging cryptocurrencies.
On p. 74 they write:
“Third, new rules such as Sarbanes-Oxley have done little to curb accounting fraud. If anything, the growing complexity of companies, more multifaceted transactions, and the speed of modern commerce create new ways to hide wrongdoing.”
This may be true, but what are the stats or examples of people violating Sarbanes-Oxley, and how do “blockchains” help with this specifically?
On p. 78 they write:
“The blockchain returns power to shareholders. Imagine that a token representing a claim on an asset, a “bitshare,” could come with a vote or many votes, each colored to a particular corporate decision. People could vote their proxies instantly from anywhere, thereby making the voting process for major corporate actions more response, more inclusive, and less subject to manipulation.”
First off, which blockchain? And how does a specific blockchain provide that kind of power that couldn’t otherwise be done with existing non-blockchain technology?
On p. 80 they quote Marc Andreessen who says:
“PayPal can do a real-time credit score in milliseconds, based on your eBay purchase history — and it turns out that’s a better source of information than the stuff used to generate your FICO score.”
But what if you do not use eBay? And why do you need a blockchain to track or generate a credit rating?
On p. 81:
“This model has proven to work. BTCjam is a peer-to-peer lending platform that uses reputation as the basis for extending credit.”
BTCjam appears to have plateaued. They currently have a low churn rate on the available loans and they exited the US market 2 months ago.
On p. 83 they write:
“The blockchain IPO takes the concept further. Now, companies can raise funds “on the blockchain” by issuing tokens, or cryptosecurities, of some value in the company. They can represent equity, bonds, or, in the case of Augur, market-maker seats on the platform, granting owners the right to decide which prediction markets the company will open.”
From a technical perspective this may be possible, but from a legal and regulatory perspective, it may not be yet. Overstock has been given permission by the SEC to experiment with issuance.
On p. 86 they write:
“Bitcoin cannot have bail-ins, bank holidays, currency controls, balance freezes, withdrawal limits, banking hours,” said Andreas Antonopoulos.
That’s not quite true. Miners can and will continue to meet at their own goals and they have the power to hard fork to change any of these policies including arbitrarily increasing or decreasing the issuance as well as changing fees for faster inclusion. They also have the ability to censor transactions altogether and potentially — if the social value on the network increases — “hold up” transactions altogether.
Also, this doesn’t count the subsidies that miners receive from the utilities.
On p. 98 they write:
“To this last characteristic, Antonopoulos notes: “If there is enough financial incentive to preserve this blockchain into the future, the possibility of it existing for tens, hundreds, or even thousands of years cannot be discounted.”
It can arguably be discounted. What evidence is presented to back up the claim that any infrastructure will last for hundreds of years?
On p. 100 they write:
“And just imagine how the Uniform Commercial Code might look on the blockchain.”
Does this mean actually embedding the code as text onto a blockchain? Or does this mean modifying the UCC to incorporate the design characteristics of a specific blockchain?
On p. 102 they write:
“What interests Andreas about the blockchain is that we can execute this financial obligation in a decentralized technological environment with a built-in settlement system. “That’s really cool,” he said, “because I could actually pay you for the pen right now, you would see the money instantly, you would put the pen in the mail, and I could get a verification of that. It’s much more likely that we can do business.”
I assume that they are talking about the Bitcoin blockchain:
there is no on-chain settlement of fiat currencies, which is the actual money people are settling with on the edges of the network
since it is not fiat currency, it does not settle instantly. In fact, users still have a counterparty risk involving delivery of the pen versus the payment.
if a central bank issued a digital currency, then there could be on-chain settlement of cash.
On p. 103 they write:
“If partners spends more time up front determining the terms of an agreement, the monitoring, enforcement, and settlement costs drop significantly, perhaps to zero. Further, settlement can occur in real time, possibly in microseconds throughout the day depending on that deal.”
The DTCC published a white paper in January that explains they can already do near real-time settlement, but T+3 exists due to laws and other market structures.
On p. 105 they write that:
“Multisig authentication is growing in popularity. A start-up called Hedgy is using multisig technology to create futures contracts: parties agree on a price of bitcoin that will be traded in the future, only ever exchanging the price difference.”
As an aside, Hedgy is now dead. Also, there are other ways to illustrate multisig utility as a financial control to prevent abuse.
On p. 106 they wrote that:
“The trouble is that, in recent business history, many hierarchies have not been effective, to the point of ridicule. Exhibit A is The Dilbert Principle, most likely one of the best-selling management books of all time, by Scott Adams. Here’s Dilbert on blockchain technology from a recent cartoon…”
The problem is that the cartoon they are citing (above) was actually a parody created by Ken Tindell last year.
The original Scott Adam’s cartoon was poking fun of databases and is from November 17, 1995.
On p. 115 they write:
“But the providers of rooms receive only part of the value they create. International payments go through Western Union, which takes $10 of every transaction and big foreign exchange off the top.”
Western Union does not have a monopoly on international payments, in fact, in many popular corridors they have less than 25% of market share. In addition, Western Union does not take a flat $10 off every transaction. You can test this out by going to their price estimator. For instance, sending $1,000 from the US to a bank account in China will cost $8.
On p. 117 they write about a fictional blockchain-based Airbnb called bAirbnb:
“You and the owner have now saved most of the 15 percent Airbnb fee. Settlements are assured and instant. There are no foreign exchange fees for international contracts. You need not worry about stolen identity. Local governments in oppressive regimes cannot subpoena bAirbnb for all its rental history data. This is the real sharing-of-value economy; both customers and service providers are the winner.”
The problem with their statement is that cash settlements, unless it is digital fiat, is not settled instantly. Identities can still be stolen on the edges (from exchanges). And, governments can still issue subpoenas and work with data analytics companies to track provenance and history.
On p. 119 they write:
“Along comes blockchain technology. Anyone can upload a program onto this platform and leave it to self-execute with a strong cryptoeconomical guarantee that the program will continue to perform securely as it was intended.”
While that may have been the case when these cryptocurrency systems first launched, in order to acquire ether (for Ethereum) or bitcoin, users must typically exchange fiat first. And in doing so, they usually dox themselves through the KYC requirements at exchanges.
On p.123-124 they write about a ‘Weather decentralized application’ but do not discuss how its infrastructure is maintained let alone the Q-o-S.
On p.127 they write:
“Using tokens, companies such as ConsenSys have already issued shares in their firms, staging public offerings without regulatory oversight.”
The legality of this is not mentioned.
On p. 128 they write:
“Could there be a self-propagating criminal or terrorist organizations? Andreas Antonopolous is not concerned. He believes that the network will manages such dangers. “Make this technology available to seven and a half billion people, 7.499 billion of those will use it for good and that good can deliver enormous benefit to society.”
How does he know this? Furthermore, the Bitcoin network itself is already available to hundreds of millions, but many have chosen not to use it. Why is this not factored into the prediction?
On p.131 they write:
“What if Wikipedia went on the blockchain — call it Blockpedia.”
The total article text of English Wikipedia is currently around 12 gigabytes. If it is a public blockchain, then how would this fit on the actual blockchain itself? Why not upload the English version onto the current Bitcoin blockchain as an experiment? What utility is gained?
From p. 129-144 they imagine seven ideas that are pitched as business ideas, but in most instances it is unclear what the value proposition that a blockchain provides over existing technology.
On p. 148 they write that:
“The Internet of Things cannot function without blockchain payment networks, where bitcoin is the universal transactional language.”
What does that mean? Does that mean that there are multiple blockchains and that somehow bitcoin transactions control other blockchains too?
On p. 152 they write:
“Last is the overarching challenge of centralized database technology — it can’t handle trillions of real-time transactions without tremendous costs.”
What are those costs? And what specifically prevents databases from doing so?
On p. 153 they write:
“Other examples are a music service, or an autonomous vehicle,” noted Dino Mark Angaritis, founder of Smartwallet, “each second that the music is playing or the car is driving it’s taking a fraction of a penny out of my balance. I don’t have a large payment up front and pay only for what I use. The provider runs no risk of nonpayment. You can’t do these things with a traditional payment networks because the fees are too high for sending fractions of a penny off your credit card.”
Depositing first and having a card-on-file are types of solutions that currently exist. “Microtipping” doesn’t really work for a number of reasons including the fact that consumers do not like to nickel and dime themselves. This is one of the reasons that ChangeTip had difficulties growing.
Furthermore, the tangential market of machine-to-machine payments may not need a cryptocurrency for two reasons:
M2M payments could utilize existing electronic payment systems via pre-paid and card-on-file solutions
The friction of moving into and out of fiat to enter into the cryptocurrency market is an unnecessary leg, especially if and when central bank digital currency is issued.
On pages 156-169 nearly all of the examples could use a database as a solution, it is unclear what value a blockchain could provide in most cases. Furthermore, on p. 159 they discuss documentation and record keeping but don’t discuss how these records tie into current legal infrastructure.
On p. 172 they write:
“We’re talking billions of new customers, entrepreneurs, and owners of assets, on the ground and ready to be deployed. Remember, blockchain transactions can be tiny, fractions of pennies, and cost very little complete.”
Maybe some transactions on some blockchains cost fractions of pennies, but currently not Bitcoin transactions.
On p.177 they write that “David Birch, a cryptographer and blockchain theorist, summed it up: “Identity is the new money.”
“Financing a company is easier as you can access equity and debt capital on a global scale, and if you’re using a common denominator — like bitcoin — you need not worry about exchange rates and conversation rates.”
Unless everyone is using one currency, this is untrue.
On p.185 they write:
“Sending one bitcoin takes about 500 bits, or roughly one one-thousandth the data consumption of one second of video Skype!”
But users still need to cash out on the other side which requires different infrastructure than Skype, namely money transmitter licenses and bank accounts.
On p. 192 they write that:
“Second, it can mean better protection of women and children. Through smart contracts, funds can be donated into escrow accounts, accessible only by women, say, for accessing food, feminine products, health care, and other essentials.”
How can a smart contract itself detect what gender the user is?
On p.194 they write:
“In jurisdictions like Honduras where trust is low in public institutions and property rights systems are weak, the bitcoin blockchain could help to restore confidence and rebuild reputation.”
How does Bitcoin do that? What are the specific ways it can?
On p. 202 they write:
“People can register their copyrights, organize their meetings, and exchange messages privately and anonymously on the blockchain.”
Which blockchain does this? There are external services like Ascribe.io that purportedly let creators take a hash of a document (such as a patent) and store it into a blockchain. But the blockchain itself doesn’t have that feature.
On p.214 they write:
“But surely a more collaborative model of democracy — perhaps one of that rewards participation such as the mining function — could encourage citizens’ engagement and learning about issues, while at the same time invigorating the public sector with the keen reasoning the nation can collectively offer.”
On p. 255 they mention that Greek citizens during 2015 would’ve bought more bitcoins if they had better access to ATMs and exchanges. But this is not true, empirically people typically try to acquire USD because it is more universal and liquid. Perhaps that changes in the future, but not at this time.
On p. 260 they write:
“The cost for having no central authority is the cost of that energy,” said Eric Jennings, CEO of Filament, an industrial wireless sensor network. That’s one side of the argument. The energy is what it is, and it’s comparable to the cost incurred in securing fiat currency.”
Where is the citation? The reason the costs of securing the Bitcoin network are currently around $400 million a year is because that is roughly the amount of capital and energy expended by miners to secure a network in which validators are unknown and untrusted. If you know who the participants are, the costs of securing a network drop by several orders of magnitude.
On p. 261 they write about the BitFury Group, a large mining company:
“Its founder and CEO, Valery Vavilov, argued the view that machines and mining operations overall will continue to get more energy efficient and environmentally friendly.”
Actually what happens is that while the ASIC chips themselves become more energy efficient, miners in practice will simply add more equipment and maintain roughly the same energy costs as a whole. That is to say, if a new chip is 2x as efficient as before, miners typically just double the acquisition of equipment — maintaining the same amount of energy consumption, while doubling the hashrate. There is no “environmental friendliness” in proof-of-work blockchains due to the Red Queen Effect.
On p. 274 they write:
“There will be many attempts to control the network,” said Keonne Rodriguez of Blockchain. “Big companies and governments will be devoted to breaking down privacy. The National Security Agency must be actively analyzing data coming through the blockchain even now.”
With thousands of copies being replicated around the world, it’s unclear who actually is storing it, perhaps intelligence agencies are. We do know that at least 10 companies are assisting compliance teams and law enforcement in tracking the provenance of cryptocurrency movements.
On p. 282 they write:
“Indeed, Mike Hearn, a prominent bitcoin core developer, caused a quite a stir in January 2015 when he wrote a farewell letter to the industry foretelling bitcoin’s imminent demise.”
“Licensed exchanges, such as Gemini, have gained ground perhaps because their institutional clientele know they’re now as regulated as banks.”
Actually, Gemini hasn’t gained ground and remains relatively flat over the past ~5 months. Even adding ether to their list of assets didn’t move the dial.
Overall the book was published a little too early as there hasn’t been much real traction in the entire ecosystem.
The content and perspective is currently skewed towards telling the cryptocurrency narrative and seemingly downplays the important role that institutions and enterprises have played over the past year in the wider distributed ledger ecosystem.
If you are looking for just one book to read on the topic, I would pass on this and wait for a future edition to rectify the issues detailed above.
Two days ago I had a chance to read through a new book called Digital Gold written by Nathaniel Popper, a journalist at The New York Times.
Popper’s approach to the topic matter is different than other books which cover cryptocurrencies (such as The Age of Cryptocurrency).
This is a character driven story, guided by about a dozen unintentional thespians — key individuals who helped develop and shape the Bitcoin world from its genesis up through at least last summer (when the book effectively tapers off). Or in other words, it flowed more like a novel than an academic textbook exegesis on the tech.
Below are some of the highlights and comments that came to mind while reading it.
I mentioned that in The Age of Cryptocurrency the authors preferred to use the term “digital currency” over “virtual currency.” I lost count of the dozens of times they used the former, but the latter was only used ~12 times (plus or minus one or two). I think from a legalese perspective it is more accurate to use the phrase “virtual currency” (see my review as to why).
While I tried to keep track of things more closely in Popper’s book, I may have missed one or two. Interestingly the index in the back uses the term “virtual money” (not currency) and the “digital currency” section is related to specific types. Below is my manual tabulation:
digital cash, p. 110
digital commodity (as categorized by the Chinese government), p. 274
digital code, p. 158
digital wallet, p. 159, 160, 179, 262 (likely many more during discussions of Lemon)
[Note: I manually typed the quotes from the book, all transcription errors are my own and should not reflect on the book itself.]
On page 38 he writes about pricing a bitcoin, “Given that no one had ever bought or sold one, NewLibertyStandard came up with his own method for determining its value — the rough cost of electricity needed to generate a coin, calculated using NewLibertyStandard’s own electricity bill.”
I have heard this story several times, NLS’s way of pricing a good/service is the 21st century continuation of the Labor Theory of Value. And this is not a particularly effective pricing mechanism: art is not worth the sum of its inputs (oils, canvas, frame, brushes). Rather the value of art, like bitcoins, is based on consumer (and speculative) demand.1
Thus when people at conferences or on reddit say that “bitcoin is valuable because the network is valuable” — this is backwards. The Bitcoin network (and bitcoins) is not valuable because the energy used to create proofs, rather it is the aggregate demand from buyers that increases (or decreases) relative to the supply of bitcoin, which is reflected in prices and therefore miners adjust consumption of energy to chase the corresponding rents (seigniorage).
On page 42 he writes, “Laszlo’s CPU had been winning, at most, one block of 50 bitcoins each day, of the approximately 140 blocks that were released daily. Once Laszlo got his GPU card hooked in he began winning one or two blocks an hour, and occasionally more. On May 17 he won twenty-eight blocks; these wins gave him fourteen hundred new coins that day.”
That translates to roughly 20% of the network hashrate.
Having noted this, the author writes:
I don’t mean to sound like a socialist,” Satoshi wrote back. “I don’t care if wealth is concentrated, but for now, we get more growth by giving that money to 100% of the people than giving it to 20%.
As a result, Satoshi asked Laszlo to go easy with the “high-powered hashing,” the term coined to refer to the process of plugging an input into a hash function and seeing what it spit out.
It’s unclear how many bitcoins Laszlo generated altogether (he was also mentioned in The Age of Cryptocurrency), but he apparently did “stock pile” at least 70,000 bitcoins whereupon he offered 10,000 bitcoins at a time buy pizzas. (Update: this address allegedly belongs to Laszlo and received 81,432 bitcoins; see Popper’s new letter on reddit)
Thus, there was at least one GPU on the network in May 2010 (though it appears he turned it off at some point). For comparison, on page 189, Popper states that “By the end of 2012 there was the equivalent of about 11,000 GPUs working away on the network.”
Later in the book, on page 191, Popper described the growth in hashrate in early 2013:
Over the next month and a half, as the rest of Avalon’s first batch of three hundred mining computers reached customers, the effect was evident on the charts that tracked the power of the entire Bitcoin network. It had taken all of 2012 for the power on the network to double, but that power doubled again in just one month after Yifu’s machines were shipped.
It’s worth re-reading the Motherboardfeature on Yifu Guo, the young Chinese man who led the Avalon team’s effort on building the first commercially available ASIC.
Above is a chart published just over a year ago (April 28, 2014) from Dave Hudson. It’s the only bonafide S-curve in all of Bitcoinland (so far).
In Hudson’s words, “The vertical axis is logarithmic and clearly shows how the hashing rate will slow down over the next two years. What’s somewhat interesting is that whether the BTC price remains the same, doubles or quadruples over that time the effect is still pronounced. The hashing rate continues to grow, but slows dramatically. What’s also important to reiterate is that these represent the highest hashing rates that can be achieved; when other overheads and profits are taken then the growth rate will be lower and flatter.”
Popper noted that this type of scaling also resulted in centralization:
Most of the new coins being released each day were collected by a few large mining syndicates. If this was the new world, it didn’t seem all that different from the old one — at least not yet. (page 336)
Moving on, on page 192, Popper writes:
The pools, though, generated concern about the creeping centralization of control in the network. It took the agreement of 5 percent of the computer power on the network to make changes to the blockchain and the Bitcoin protocol, making it hard for the one person to dictate what happened. But with the mining pools, the person running the pool generally had voting power for the entire pool — all the other computers were just worker bees. (page 192)
I think there is a typo here. He probably meant 51% of the hashrate, not 5%. Also, it may be more precise to say “actor” because in practice it is individuals at organizations that operate the farms and pools, not usually just one person.
On page 52 the author discussed the earliest days of Mt. Gox in 2010:
Mt. Gox was a significant departure from the exchange that already existed, primarily because Jed offered to take money from customers into his PayPal account and thereby risk violating the PayPal prohibition on buying and selling currencies. This meant that Jed could receive funds from almost anywhere in the world. What’s more, customers didn’t have to send Jed money each time they wanted to do a trade. Instead, they could hold money — both dollars and Bitcoin — in Jed’s account and then trade in either direction at any time as long as they had sufficient funds, much as in a traditional brokerage account.
Needless to say, Jed’s PayPal account eventually got shut down.
On page 65 the author briefly discusses the life of Mark Karpeles (the 2nd owner of Mt. Gox):
Since then, he’d had a peripatetic lifestyle, looking for a place where he could feel at home. He first tried Israel, thinking it might help him get closer to his Catholicism, but he soon felt as lonely as ever, and the servers he was running kept getting disrupted by rocket fire from Gaza.
Initially I thought Popper meant to write Judaism instead of Catholicism (Karpeles is a Jewish surname), but a DailyTecharticle states he is Catholic based on one of his blog posts.
On page 67 he writes:
But as the headaches continued to pile up, Jed got more antsy. In January, a Mt. Gox user named Baron managed to hack into Mt. Gox accounts and steal around $45,000 worth of Bitcoins and another type of digital currency that Jed had been using to transfer money around.
It’s not clear what the the other digital currency actually was — based on the timeline (January 2011) this is before Jed created XRP for OpenCoin (which later became Ripple Labs).
Also, I believe this is the first time in the book where the term “digital currency” is used.
On page 77 he writes about Roger Ver:
In the midst of his campaign for the assembly, federal agents arrested Roger for peddling Pest Control Report 2000 — a mix between a firecracker and a pest repellent — on eBay. Roger had bought the product himself through the mail and he and his lawyer became convinced that the government was targeting Roger because of remarks he had made at a political rally, where had had called federal agents murderers.
This version of the story may or may not be true.
Either way, part of Ver’s 2002 case was unsealed last fall and someone sent me a copy of it (you can find the full version at PACER). Below are a few quotes from the document (pdf) hosted at Lesperance & Associates between the prosecution (Mr. Frewing) and the judge presiding over the case.
“Mr. Ver’s conduct was serious. I think one factor that the Court can take into consideration or at least should consider is there were some pipe bombs involved in this case as well that were not charged and are not incorporated in the conduct that’s before the Court except arguably as relevant conduct. The split sentence is — would result only in five months incarceration for what I think is a fairly serious offense. It’s my recommendation to do the ten-month sentence in prison in total.”
Judge: “Well, I’ve given this case a lot of thought. I’m very troubled by it. And when I say that I’m troubled by it I’m troubled by it in several ways. Not only am I troubled by the underlying conduct, which is quite serious, but I don’t want to overreact either and I think that’s what makes it hard.I think if you have a case which strikes you as being particularly severe, in a way that’s kind of an easy thing to just say all right, we’ll throw the book at the defendant and that will satisfy that impulse.”
“But I don’t think judges ought to sentence anybody impulsively. You have to look at the offense and you have to look at the person who committed it. There are elements in the probation report and in Dr. Missett’s report which concern me a great deal. One has to be very careful. Mr. Ver, you’re a young man and you’ve led a law-abiding life for the last two years and you’ve by all accounts performed well on pretrial release. I did note in your letter that you accepted that your conduct was illegal, and I appreciate that. I also don’t in any way want to confuse your political beliefs, which you are absolutely entitled to have, with your criminal conduct. There’s a long and honorable tradition of libertarian politics in our country and I don’t mean to in any way hold that against you. It’s something that you’re entitled to have. The problem, though, is that the law is a representation of authority in a certain way. People can disagree and they can disagree very vigorously and very reasonably about what ought to be legal and what ought not to be legal and how much the Government ought to do or ought not to do. But there is a point at which we start talking about public safety and I think even the most die hard libertarian would agree that one function of government, if there is to be a government, is to protect public safety. So then it’s just a question of how you do it, how you do it in a way that’s least invasive of individual liberties. Selling explosives over the Internet doesn’t cut it in any society that I can imagine and I think it’s — the conduct here is simply not tolerable conduct and it’s not — I don’t think one has to be a big government person or believe in government regulation of every aspect of human life to suggest that people should not be selling explosives over the Internet. The other thing that concerns me is that in looking at your social history it seems to me you’ve got some reasons for not trusting authority, and that’s. I mean, those are feelings that are a product of your life experience. Nonetheless, those feelings don’t give you the right to be above the same social constraints that bind all of us.”
“And I’m not saying this as well as I’d like to, but I think there’s a difference between saying I believe that the government which governs best governs least and saying that I’m above the law totally, that I’m so smart, I’m so able, I’m so perceptive that I don’t have to follow the rules that apply to other human beings. There’s a difference between those two positions. And while one of them is a very respectable position that I think any judge ought to uphold and support rather than punish, the other I think is why we have courts. It’s when a person believes that he or she is so important and so intelligent and so much better than everybody else that they don’t have to follow even the most basic rules that keep us together in this society.”
“I think that these offenses are very serious. They could have been a lot more serious. The bombs could have gone off or people could have used them in destructive ways. Selling bombs to juveniles is never okay. I’d like to say that the five and five sentence that your attorney proposed is something that I’m comfortable with, but I just can’t. And it’s not a desire to be overly punitive or to send you a message. It’s simply saying that this conduct — when the law punishes behavior, criminal law is directed at conduct. This conduct to me would have warranted a much stiffer sentence than ten months. There’s a plea agreement. I’m bound by it. I’m not going to upset it. It was arrived at in good faith by the Government and by the defense and I will respect it, but I’m not going to dilute it.”
This will probably not be the last time the background and origin story of the characters in this journey are looked at.
On social media there is frequent talk of large “whales” and “bear whales” that are blamed for large up and down swings in prices.
Popper identified a few of them in the book.
For instance, on page 79 he writes about Roger Ver’s initial purchases:
In April 2011, after hearing about Bitcoin on Free Talk Live, he used his fortune to dive into Bitcoin with a savage ferocity. He sent a $25,000 wire to the Mt. Gox bank account in New York — one Jed had set up — to begin buying Bitcoins. Over the next three days, Roger’s purchases dominated the markets and helped push the price of a single coin up nearly 75 percent, from $1.89 to $3.30.
Another instance, on page 113:
But the people ignoring Jed’s advice ended up giving Bitcoin momentum at a time when it was otherwise lacking. Roger alone bought tens of thousands of coins in 2011, when the price was falling, single-handedly helping to keep the price above zero (and establishing the foundation for a future fortune).
Over the past year I have frequently been asked: why did the price begin increasing after the block reward halving at the end of November 2012? Where did the price increase come from?
A number of people, particularly on reddit, conflate causation with correlation: that somehow the block halving caused a price increase. As previously explored, this is incorrect.
So if it wasn’t the halvening, what then led to the price increase?
In January 2013, Popper looked at the Winklevoss twins:
The twins considered selling to Roger. But they also believed BitInstant was a good idea that could work under the right management. In January BitInstant had its best month ever, processing almost $5million in transactions. The price of a Bitcoin, meanwhile, had risen from $13 at the beginning of the month to around $18 at its end. Some of this was due to the twins themselves. They had asked Charlie to continue buying them coins with the goal of owning 1 percent of all Bitcoins in the world, or some $2 million worth at the time. This ambition underscored their commitment to sticking it out with Bitcoin. (page 175)
Simultaneously, another group of wealthy individuals, from Fortress Investment Group were purchasing bitcoins:
Pete assigned Tanona to the almost full-time job of exploring potential Bitcoin investments, and also drew in another top Fortress official, Mike Novogratz. All of them began buying coins in quantities that were small for them, but that represented significant upward pressure within the still immature Bitcoin ecosystem.
The purchases being made by Fortress — and by Mickey’s team at Ribbit — were supplemented by those being made by the Winklevoss twins, who were still trying to buy up 1 percent of all the outstanding Bitcoins. Together, these purchases helped maintain the sharp upward trajectory of Bitcoin’s price, which rose 70 percent in February after the 50 percent jump in January. On the evening of February 27 the price finally edged above the long-standing record of $32 that had been set in the hysterical days before the June 2011 crash at Mt. Gox. (p. 180)
Initially discussed introduction, Popper explains when Wences first met Pete Briger (p. 163, from Fortress Investment Group) during a January 2013 lodge in the Canadian Rockies.
A few pages later, in early March 2013, Wences is invited to a private retreat held at the Ritz Carlton in Tucson, Arizona hosted by Allen & Co. There he met with and explained Bitcoin to: Dick Costolo, Reid Hoffman, James Murdoch, Marc Andreessen, Chris Dixon, David Marcus, John Donahoe, Henry Blodget, Michael Ovitz and Charlie Songhurst.
During this conference it appears several of these affluent individuals began buying bitcoins:
On Monday, the first full day of the conference, the price of Bitcoin jumped by more than two dollars, to $36, and on Tuesday it rose by more than four dollars — its sharpest rise in months — to over $40. On Wednesday, when everyone flew home, Blodget put up a glowing item on his heavily read website, Business Insider, mentioning what he’d witnessed (though not specifying where exactly he’d been, or whom he’d talked to)” (page 184)
To prove how easy this all was, Wences asked Blodget to take out his phone and helped him create an empty Bitcoin wallet. Once it was up, and Wences had Blodget’s new Bitcoin address, Wences used the wallet on his own phone to send Blodget $250,000, or some 6,400 Bitcoins. The money was then passed to the phones of other people around the table once they had set up wallets. Anyone could have run off with Wence’s $250,000, but that wasn’t a risk with this particular crowd. Instead, as the money went around, Wences saw the guests’ laughter and wide-eyed amazement at what they were watching. (page 183)
It would be interesting to do some blockchain forensics (such as Total Output Volume and Bitcoin Days Destroyed) to see if we can identify a blob of 6,400 bitcoins moving around on March 3-5 maybe five to ten different times (it is unclear from the story how many people it was sent to).
And finally a little more whale action to round out the month:
The prices certainly suggested certainly suggested that someone with lots of money was buying. In California, Wences Casares knew that no small part of the new demand was coming from the millionaires whom he had gotten excited about Bitcoin earlier in the month and who were now getting their accounts opened and buying significant quantities of the virtual currency. They helped push the price to over $90 in the last week of March. At that price, the value of all existing coins, what was referred to as the market capitalization, was nearing $1 billion. (page 198)
The following month, in April, during the run-up on Mt. Gox which later stalled and crashed under the strain of traffic:
The day after the crash, the Winklevoss twins finally went public in the New York Times with their now significant stake in Bitcoin — worth some $10 million. (page 211)
The twins didn’t want to buy coins while the price was still dropping, but when they saw it begin to stabilize, Cameron, who had done most fo the trading, began placing $100,000 orders on Bitstamp, the Slovenian Bitcoin exchange. Cameron compared the moment to a brief time warp that allowed them to go back and buy at a a lower price. They had almost $1 million in cash sitting with Bitstamp for exactly this sort of situation, and Cameron now intended to use it all.” (page 251)
Prices were around $110 – $130 each so they may have picked up an additional ~9,000 bitcoins or so.
Interestingly enough, Popper wrote the same New York Timesarticle (cited above) that discussed the Winklevoss holdings. In the same article he also noted another active large buyer during the same month:
A Maltese company, Exante, started a hedge fund that the company says has bought up about 82,000 bitcoins — or about $10 million as of Thursday — with money from wealthy investors. A founder of the fund, Anatoli Knyazev, said his main concern was hackers and government regulators, who have so far mostly left the currency alone.
The tl;dr of this information is that between January through March 2013, at least a dozen or so high-net-worth individuals collectively bought tens of millions of dollars worth of bitcoin. The demand of which resulted in a rapid increase in market prices. This had nothing to do with the block reward halving, just a coincidence.
Interwoven amount the story line are examples illustrating the trials and tribulations of securing bearer assets with new financial institutions that lack clear (if any) financial controls including Bitomat (which lost 17,000 bitcoins) and MyBitcoin (at least 25,000 bitcoins were stolen from).
It also discussed some internal dialogue at both Google and Microsoft.
According to Popper, Google, WellsFargo, PayPal, Microsoft all had high level individuals and teams looking at Bitcoin in early 2013. On page 101, Osama Abedier from Google, spoke with Mike Hearn and said, “I would never admit it outside this room, but this is how payments probably should work.”
Popper cites a paper that Charlie Songhurst, head of corporate strategy at Microsoft, wrote after the Ritz Carlton event, channeling Casares’s arguments:
“We foresee a real possibility that all currencies go digital, and competition eliminates all currencies from noneffective governments. The power of friction-free transactions over the Internet will unleash the typical forces of consolidation and globalization, and we will end up with six digital currencies: US Dollar, euro, Yen, Pound, Renminbi and Bitcoin.”
I didn’t keep track of the phrase “digital gold” but I believe it only appeared twice. Unsurprisingly, this phrase came about via some of the ideological characters he looked at.
In Wences’ view:
“Unlike gold, it could be easily and quickly transferred anywhere in the world, while still having the qualities of divisibility and verifiability that had made gold a successful currency for so many years.” (Page 109)
Unlike gold, which was universal but difficult to acquire and hold, Bitcoins could be bought, held, and transferred by anyone with an internet connection, with the click of a mouse.
“Bitcoin is the first time in five thousands years that we have something better than gold, ” he said. “And its not a little bit better, it’s significantly better. It’s much more scarce. More divisible, more durable. It’s much more transportable. It’s just simply better.” (p. 165)
The specific trade-offs between precious metals and cryptocurrencies is not fully fleshed out, but that probably would have detracted from the overall narrative. Of maybe not.
Meet and greet:
“The Bitcoin forum was full of people talking about their experiences visiting Zuccotti Park and other Occupy encampments around the country to advertise the role that a decentralized currency could play in bringing down the banks.” (p. 111)
Who isn’t meddling?
“Few things occupied the common ground of this new political territory better than Bitcoin, which put power in the hands of the people using the technology, potentially obviating overpaid executives and meddling bureaucrats.” (p. 112)
I thought that was a tad distracting, it’s never really discussed what “overpaid” or “meddling” are. Perhaps if there is a second edition, in addition to clarifying those we can have a chance to look at some of the sock puppets that a variety of these characters may have been operating too.
Public goods problem:
Many libertarians and anarchists argued that the good in humans, or in the market, could do the job of regulators, ensuring that bad companies did not survive. But the Bitcoin experience suggested that the penalties meted out by the market are often imposed only after the bad deeds were done and do not serve as a deterrent. (p. 114)
“You don’t have to battling all of the government’s problems, you aren’t going to buy bread with it, but it’ll save you if you have a stash of stable currency that tends to appreciate in value,” twenty-two-year-old Emmanuel Ortiz told the newspaper (page 241)
There is no real discussion between the trade-offs of rebasing a currency to maintain purchasing power and its unclear why Ortiz thinks that an asset that fluctuates 10% or more each month is considered stable.
It’s unclear how many of the salacious stories were left on the cutting board, but there is always Brian Eha’s upcoming book.
It turned out that Charlie’s willingness to throw things at the wall, to see if they would stick, was not a bad thing at this point. The idealists who had been driving the Bitcoin world often got caught up in what they wanted the world to look like, rather than figuring out how to provide the world with something it would want. (page 129)
Hacking for fun and profit. How secure is the code? On page 154:
After quietly watching and playing with it for some time, Wences gave $100,000 of his own money to two high-level hackers he knew in eastern Europe and asked them to do their best to hack the Bitcoin protocol. He was especially curious about whether they could counterfeit Bitcoins or spend the coins held in other people’s wallets — the most damaging possible flaw. At the end of the summer, the hackers asked Wences for more time and money. Wences ended up giving them $150,000 more, sent in Bitcoins. In October they concluded that the basic Bitcoin protocol was unbreakable, even if some of the big companies holding Bitcoins were not.
I’m sure we would all like to see more of the study, especially Tony Arcieri who wrote a lengthy essay a couple days ago on some potential issues with cryptographic curves/methods used in Bitcoin.
A little irony on page 162:
For Wences, Bitcoin seemed to address many of the problems that he’d long wanted to solve, providing a financial account that could be opened anywhere, by anyone, without requiring permission from any authority. He also saw an infant technology that he believed he could help grow to dimensions greater than anything he had previously achieved.
Permissionless systems seems to be everyone’s goal, yet everyone keeps making trusted third parties which inevitably need to VC funding to scale and with it, regulatory compliance which then creates a gated, permission-based process.
Altruism on the part of BTC Guild during the fork/non-fork issue in March 2013:
The developers on the chat channel thanks him, recognizing that he was sacrificing for the greater good. When he finally had everything moved about an hour later, Eleuthria took stock on his own costs (page 195)
“The network had not had to rely on some central authority to wake up to the problem and come up with a solution. Everyone online had been able to respond in real time, as was supposed to happen with open source software, and the user had settled on a response after a debate that tapped the knowledge of all of them — even when it meant going against the recommendation of the lead developer, Gavin.” (page 195)
Origins of Xapo:
They started by putting all their private keys on a laptop, with no connection to the Internet, thus cutting off access for potential hackers. After David Marcus, Pete Briger, and Micky Malka put their private keys on the same offline laptop, the men paid for a safe-deposit box in a bank to store the computer more securely. In case the computer gave out, they also put a USB drive with all the private keys in the safe-deposit box. (page 201)
First, they encrypted all the information on the laptop so that if someone got hold of the laptop that person still wouldn’t be able to get the secret keys. They put the keys for decrypting the laptop in a bank near Feede in Buenos Aires. Then they moved the laptop from a safe-deposit box to a secure data center in Kansas City. By this time, the laptop was holding the coins of Wences, Fede, David Marcus, Pete Briger, and several other friends. The private keys on the laptop were worth tens of millions of dollars. (page 281)
I heard a similar story regarding the origins of BitGo, that Mike Belshe used to walk around with a USB drive on his key chain that had privkey’s to certain individual accounts. This is before the large upsurge in market value. When the prices began to rise he realized he needed a better solution. Perhaps this story is more apocryphal than real, but I suspect there have been others whose operational security was not the equivalent of Fort Knox prior to 2013.
An unnamed Alex Waters appears twice:
“The new lead developer called for the entire site to be taken down and rebuilt. But there wasn’t time as a new customers were pouring money into the site. The new staff members were jammed into every corner of the small offices Charlie and Erik had moved into the previous summer.” (page 202)
“But as problems became more evident, they talked with Charlie’s chief programmer about replacing Charlie as CEO. When Charlie learned about the potential palace coup he was furious and began showing up for work less and less.” (page 221)
For those unfamiliar with Alex, he was the CTO of BitInstant who went on to co-found CoinValidation and then currently, Coin.co & Coinapex.
Last week I had a chance to meet with him in NYC.

Yesterday I reached out to Alex about the two quotes above related to BitInstant and this is what he sent (quoted with permission):
“It was sad to see Bitinstant take such a drastic turn after the San Jose conference. It was as if we built a gold mine and couldn’t stop someone from taking dynamite into it. A lot of good people worked at Bitinstant (like 25 people) and the 2.0 product we wanted to launch was outstanding. It’s frustrating that some poor decisions early in the company’s history put pressure on such an important moment. A lot of us who worked there worked really hard with sleepless nights for months on a relaunch that never made it to the public. Those people didn’t list Bitinstant on their resume after the collapse as it was so clearly tainted. The quality of those people’s work was outstanding, and they had no part or knowledge of anything illegal. Our compliance standards were beyond reproach for the industry.”
Just two months ago Coinbase was in the news due to some issues with their pitch deck (pdf) as it related to marketing Bitcoin as a method for bypassing country specific sanctions.
However two years ago they ran into a slightly different issue:
In order to stay on top of anti-money laundering laws, the bank had to review every single transaction, and these reviews cost the bank more money than Coinbase was brining in. The bank imposed more restrictions on Coinbase than on other customers because Bitcoin inherently made it easier to launder money. (page 203)
Coinbase had to repeatedly convince Silicon Valley Bank that it knew where the Bitcoins leaving Coinbase were going. Even with all these steps, on several days in March Coinbase hit up against transaction limits set by Silicon Valley Bank and had to shut down until the next day. (page 204)
Not quite accurate
In looking at my notes in the margin I didn’t find many inaccuracies. Two small ones that stood out:
In early December Roger used some of his Bitcoin holdings, which had gone up in value thousands of times, to make a $1 million donation to the Electronic Frontier Foundation, an organization that had been started by a former Cypherpunk to defend online privacy, among other things. (page 270)
Actually, Ver donated $1 million worth of bitcoins to FEE, the Foundation for Economic Education not EFF.
But over time the two Vals kept more and more of the computers for themselves and put them in data centers spread around the world, in places that offered cheap energy, including the Republic of Georgia and Iceland. These operations were literally minting money. Val Nebesny was so valuable that Bitfury did not disclose where he lived, though he was rumored to have moved from Ukraine to Spain. And Bitfury was so good that it soon threatened to represent more than 50 percent of the total mining power in the world; this would give it commanding power over the functioning of the network. The company managed to assuage concerns, somewhat, only when it promised never to go above 40 percent of the mining power online at any time. Bitfury, of course, had an interest in doing this because if people lost faith in the network, the Bitcoins being mind by the company would become worthless. (page 330)
While the two Val’s did create Bitfury, I am fairly certain the scenario that is described above is that of the GHash.io mining pool (managed by CEX.io) during the early summer of 2014. At one point in mid-June 2014, the GHash pool was regularly winning 40% or more of the blocks on several days. Subsequently the CIO attemptedto assuage concerns by stating they will make sure their own pool doesn’t go above a self-imposed threshold of 40%.
I spent some time discussing this use-case in the previous review:
On Patrcik Murck: “But he was able to cogently explain his vision of how the blockchain technology could make it easier for poor immigrants to transfer money back home and allow people with no access to a bank account or credit card to take part in the Internet economy.” (page 235)
I think Yakov Kofner’s piece last month outlines the difficult challenges facing “rebittance” companies many of whom are ignoring the long term customer acquisition and compliance costs (not to mention the cash-in/cash-out hurdles).2 That’s not to say they will not be overcome, but it is probably not the slam dunk that Bitprophets claim it is.
The notion that Bitcoin could provide a new payment network was not terribly new. This is what Charlie Shrem had been talking about back in 2012, and BitPay was already using the network to charge lower transaction fees than the credit card networks.” (page 272)
Temporarily. The problem is, after all the glitzy free PR splash in 2014, there was almost no real uptake. So the sales and business development teams at payment processors now have a difficult time showing actual traction to future clients so that they too will begin using the payment processors. See for instance, BitPay’s numbers.
For example, on page 352 the author notes that:
It might have just been the exhaustion, but Wences was sourly dismissive of all the talk about Bitcoin’s potential as a new payment system. He was an investor in Bitpay but he said that fewer than one hundred thousand individuals had actually purchased anything using Bitpay.
“There is no payment volume, ” he scoffed. “It’s a sideshow.”
“But in interviews he emphasized the more practical reasons for any company to make the move: no more paying the credit card companies 2.5 percent for each transaction (the company helping Overstock take Bitcoin, Coinbase, charged Overstock 1 percent)…”
“This was attractive to merchants because BitPay charged around 1 percent for its service while credit card networks generally charged between 2 and 3 percent per transaction.” p. 134
While I have no inside knowledge of their specific arrangement, I believe the promotional pitch is 0% for the first $1 million processed and 1% thereafter. Overstock processed about $3 million last year. And the BitPay fee appears to be unsustainable (see my previous book review on The Age of Cryptocurrency as well as the BitPay number’s breakdown).
Probably not true:
The potential advantages of Bitcoin over the existing system were underscored in late December, when it was revealed that hackers had breached the payment systems of the retail giant Target and made off with the credit card information of some 70 million Americans, from every bank and credit card issuer in the country. This brought attention to an issue that Bitcoiners had long been talking about: the relative lack of privacy afforded by traditional payment systems. When Target customers swiped their credit cards at a register, they handed over their account number and expiration date. For online purchases Target also had to gather the addresses and ZIP codes of customers, to verify transactions. If the customers had been using Bitcoin, they could have sent along their payments without giving Target any personal information at all. (page 289)
In theory, yes, if users control their own privkey on their own devices. In practice, since most users use trusted third parties like Coinbase, Xapo and Circe, a hacker could potentially retrieve the same personal information from them; furthermore, because some merchants collect and require KYC then they are also vulnerable to identity theft.
What’s more, Coinbase customers didn’t have to download the somewhat complicated Bitcoin software and thew hole blockchain, with its history of all bitcoin transactions. This helped turn Coinbase into the go-to-company for Americans looking to acquire Bitcoins and helped expand the audience for the technology. (page 237)
That’s a silo-coin. Useful and helpful to on-ramping people. But effectively a bank in practice. Why not just use a real bank instead?
The more you know:
I thought the short explanation of hashcash on page 18 was good.
Was a little surprised that Eric Hughes was mentioned, but not Tim May.
On page 296, Xapo raised $40 million at a $100 million valuation in less than a couple months and on page 306, was banked by Silicon Valley Bank (which Coinbase also uses).
The Dread Pirate Roberts / Silk Road storyline that Popper discusses is upstaged by recent events that did not have a chance to make it into the book. This includes the arrest of a DEA agent and Secret Service agent who previously worked on the Silk Road case for their respective agencies.
This JPMorgan group began secretly working with the other major banks in the country, all of which are part of an organization known as The Clearing House, on a bold experimental effort to create a new blockchain that would be jointly run by the computers of the largest banks and serve as the backbone for a new, instant payment system that might replace Visa, MasterCard, and wire transfers. Such a blockchain would not need to rely on the anonymous miners powering the Bitcoin blockchain. But it could ensure there would no longer be a single point of failure in the payment network. If Visa’s system came under attack, all the stores using Visa were screwed. But if one bank maintaining a blockchain came under attack, all the other banks could keep the blockchain going.
While the The Clearing House is not secretive, the project to create an experimental blockchain was; this is the first I had heard of it.
I had a chance to meet Nathaniel Popper about 14 months ago during the final day of Coinsummit. We chatted a bit about what was happening in China and potential angles for how and why the mainland mattered to the overall Bitcoin narrative.
There is only so much you can include in a book and if I had my druthers I would have liked to add perhaps some more on the immediate history pre-Bitcoin: projects such as the now-defunct Liberty Reserve (which BitInstant was allegedly laundering money for) and the various dark net markets and online poker sites that were shut down prior to the creation of Bitcoin yet whose customer base would go on to eventually adopt the cryptocurrency for payments and bets (making up some of the clientele for SatoshiDice and other Bitcoin casinos).
Similarly, I would have liked to have looked at a few of the early civil lawsuits in which some of the early adopters were part of. For instance, the Bitcoinica lawsuit is believed to be the first Bitcoin-related lawsuit (filed in August 2012) and includes several names that appeared throughout the book: plaintiffs: Brian Cartmell, Jed McCaleb, Jesse Powell and Roger Ver; defendants: Donald Norman, Patrick Strateman and Amir Taaki. The near collapse of the Bitcoin Foundation and many of its founders would make an interesting tale in a second edition, particularly Peter Vessenes (former chairman of the board) whose ill-fated Coinlab and now-bankrupt Alydian mining project are worth closer inspection.
Overall I think this was an easy, enjoyable read. I learned a number of new things (especially related to the amount of large purchases in early 2013) and think its worth looking at irrespective of your interest in internet fun bux.
On my trip to Singapore two weeks ago I read through a new book The Age of Cryptocurrency, written by Michael Casey and Paul Vigna — two journalists with The Wall Street Journal.
Let’s start with the good. I think Chapter 2 is probably the best chapter in the book and the information mid-chapter is some of the best historical look on the topic of previous electronic currency initiatives. I also think their writing style is quite good. Sentences and ideas flow without any sharp disconnects. They also have a number of endnotes in the back for in-depth reading on certain sub-topics.
In this review I look at each chapter and provide some counterpoints to a number of the claims made.
[Note: I manually typed the quotes from the book, all transcription errors are my own and should not reflect on the book itself.]
The book starts by discussing a company now called bitLanders which pays content creators in bitcoin. The authors introduce us to Francesco Rulli who pays his bloggers in bitcoin and tries to forbid them from cashing out in fiat, so that they create a circular flow of income.1 One blogger they focus on is Parisa Ahmadi, a young Afghani woman who lacks access to the payment channels and platforms that we take for granted. It is a nice feel good story that hits all the high notes.
Unfortunately the experience that individuals like Ahmadi, are not fully reflective of what takes place in practice (and this is not the fault of bitLanders). For instance, the authors state on p. 2 that: “Bitcoins are stored in digital bank accounts or “wallets” that can be set up at home by anyone with Internet access. There is no trip to the bank to set up an account, no need for documentation or proof that you’re a man.”
This is untrue in practice. Nearly all venture capital (VC) funded hosted “wallets” and exchanges now require not only Know-Your-Customer (KYC) but in order for any type of fiat conversion, bank accounts. Thus there is a paradox: how can unbanked individuals connect a bank account they do not have to a platform that requires it? This question is never answered in the book yet it represents the single most difficult aspect to the on-boarding experience today.
Starting on page 3, the authors use the term “digital currency” to refer to bitcoins, a practice done throughout the remainder of the book. This contrasts with the term “virtual currency” which they only use 12 times — 11 of which are quotes from regulators. The sole time “virtual currency” is not used by a regulator to describe bitcoins is from David Larimer from Invictus (Bitshares). It is unclear if this was an oversight.
Is there a difference between a “digital currency” and “virtual currency”? Yes. And I have made the same mistake before.
Cryptocurrencies such as bitcoin are not digital currencies. Digital currencies are legal tender, as of this writing, bitcoins are not. This may seem like splitting hairs but the reason regulators use the term “virtual currency” still in 2015 is because no jurisdiction recognizes bitcoins as legal tender. In contrast, there are already dozens of digital currencies — nearly every dollar that is spent on any given day in the US is electronic and digital and has been for over a decade. This issue also runs into the discussion on nemo datdescribed a couple weeks ago.
On page 4 the authors very briefly describe the origination of currency exchange which dates back to the Medici family during the Florentine Renaissance. Yet not once in the book is the term “bearer asset” mentioned. Cryptocurrencies such as bitcoin are virtual bearer instruments and as shown in practice, a mega pain to safely secure. 500 years ago bearer assets were also just as difficult to secure and consequently individuals outsourced the security of it to what we now call banks. And this same behavior has once again occurred as large quantities — perhaps the majority — of bitcoins now are stored in trusted third party depositories such as Coinbase and Xapo.
Why is this important?
Again recall that the term “trusted third party” was used 11 times (in the body, 13 times altogether) in the original Nakamoto whitepaper; whoever created Bitcoin was laser focused on building a mechanism to route around trusted third parties due to the additional “mediation and transaction costs” (section 1) these create. Note: that later on page 29 they briefly mentioned legal tender laws and coins (as it related to the Roman Empire).
On page 8 the authors describe the current world as “tyranny of centralized trust” and on page 10 that “Bitcoin promises to take at least some of that power away from governments and hand it to the people.”
While that may be a popular narrative on social media, not everyone involved with Bitcoin (or the umbrella “blockchain” world) holds the same view. Nor do the authors describe some kind of blue print for how this is done. Recall that in order to obtain bitcoins in the first place a user can do one of three things:
purchase bitcoins from some kind of exchange
receive them for payments (e.g., merchant activity)
In practice mining is out of the hands of “the people” due to economies of scale which have trended towards warehouse mining – it is unlikely that embedded ASICs such as from 21 inc, will change that dynamic much, if any. Why? Because for every device added to the network a corresponding amount of difficulty is also added, diluting the revenue to below dust levels. Remember how Tom Sawyer convinced kids to whitewash a fence and they did so eagerly without question? What if he asked you to mine bitcoins for him for free? A trojan botnet? While none of the products have been announced and changes could occur, from the press release that seems to be the underlying assumption of the 21 inc business model.
In terms of the second point, nearly all VC funded exchanges require KYC and bank accounts. The ironic aspect is that “unbanked” and “underbanked” individuals often lack the necessary “valid” credentials that can be used by cheaper automated KYC technology (from Jumio) and thus expensive manual processing is done, costs that must be borne by someone. These same credential-less individuals typically lack a bank account (hence the name “unbanked”).
Lastly with the third point, while there are any number of merchants that now accept bitcoin, in practice very few actually do receive bitcoins on any given day. Several weeks ago I broke down the numbers that BitPay reported and the verdict is payment processing is stagnant for now.
Why is this last point important to what the authors refer to as “the people”?
Ten days after Ripple Labs was fined by FinCEN for not appropriately enforcing AML/KYC regulations, Xapo — a VC funded hosted wallet startup — moved off-shore, uprooting itself from Palo Alto to Switzerland. While the stated reason is “privacy” concerns, it is likely due to regulatory concerns of a different nature.
In his interview with CoinDesk last week, Wences Casares, the CEO and founder of Xapo noted that:
Still, Casares indicated that Xapo’s customers are most often using its accounts primarily for storage and security. He noted that many of its clientele have “never made a bitcoin payment”, meaning its holdings are primarily long-term bets of high net-worth customers and family offices.
“Ninety-six percent of the coins that we hold in custody are in the hands of people who are keeping those coins as an investment,” Casares continued.
96% of the coins held in custody by Xapo are inert. According to a dated presentation, the same phenomenon takes place with Coinbase users too.
Perhaps this behavior will change in the future, though, if not it seems unclear how this particular “to the people” narrative can take place when few large holders of a static money supply are willing to part with their virtual collectibles. But this dovetails into differences of opinion on rebasing money supplies and that is a topic for a different post.
On page 11 the authors describe five stages of psychologically accepting Bitcoin. In stage one they note that:
Stage One: Disdain. Not even denial, but disdain. Here’s this thing, it’s supposed to be money, but it doesn’t have any of the characteristics of money with which we’re familiar.
I think this is unnecessarily biased. While I cannot speak for other “skeptics,” I actually started out very enthusiastic — I even mined for over a year — and never went through this strange five step process. Replace the word “Bitcoin” with any particular exciting technology or philosophy from the past 200 years and the five stage process seems half-baked at best.
On page 13 they state, “Public anxiety over such risks could prompt an excessive response from regulators, strangling the project in its infancy.” Similarly on page 118 regarding the proposed New York BitLicense, “It seemed farm more draconian than expected and prompted an immediate backlash from a suddenly well-organized bitcoin community.”
This is a fairly alarmist statement. It could be argued that due to its anarchic code-as-law coupled with its intended decentralized topology, that it could not be strangled. If a certain amount of block creating processors (miners) was co-opted by organizations like a government, then a fork would likely occur and participants with differing politics would likely diverge. A KYC chain versus an anarchic chain (which is what we see in practice with altchains such as Monero and Dash). Similarly, since there are no real self-regulating organizations (SRO) or efforts to expunge the numerous bad actors in the ecosystem, what did the enthusiasts and authors expect would occur when regulators are faced with complaints?
With that said — and I am likely in a small minority here — I do not think the responses thus far from US regulators (among many others) has been anywhere near “excessive,” but that’s my subjective view. Excessive to me would be explicitly outlawing usage, ownership and mining of cryptocurrencies. Instead what has occurred is numerous fact finding missions, hearings and even appearances by regulators at events.
On page 13 the authors state that “Cryptocurrency’s rapid development is in some ways a quirk of history: launched in the throes of the 2008 financial crisis, bitcoin offered an alternative to a system — the existing financial system — that was blowing itself up and threatening to take a few billion people down with it.”
This is retcon. Satoshi Nakamoto, if he is to be believed, stated that he began coding the project in mid-2007. It is more of a coincidence than anything else that this project was completed around the same time that global stock indices were at their lowest in decades.
On page 21 the authors state that, “Bitcoin seeks to address this challenge by offering users a system of trust based not on human being but on the inviolable laws of mathematics.”
While the first part is true, it is a bit cliche to throw in the “maths” reason. There are numerous projects in the financial world alone that are run by programs that use math. In fact, all computer programs and networks use some type of math at their foundation, yet no one claims that the NYSE, pace-makers, traffic intersections or airplanes are run by “math-based logic” (or on page 66, “”inviolable-algorithm-based system”). A more accurate description is that Bitcoin’s monetary system is rule-based, using a static perfectly inelastic supply in contrast to either the dynamic or discretionary world humans live in. Whether this is desirable or not is a different topic.
On page 26 they describe the Chartalist school of thought, the view that money is political, that “looks past the thing of currency and focuses instead on the credit and trust relationships between the individual and society at large that currency embodies” […] “currency is merely the token or symbol around which this complex system is arranged.”
This is in contrast to the ‘metallist’ mindset of some others in the Bitcoin community, such as Wences Casares and Jon Matonis (perhaps there is a distinct third group for “barterists”?).
I thought this section was well-written and balanced (e.g., appropriate citation of David Graeber on page 28; and description of what “seigniorage” is on page 30 and again on page 133).
On page 27 the authors write, “Yet many other cryptocurrency believers, including a cross section of techies and businessmen who see a chance to disrupt the bank centric payments system are de facto charatalists. They describe bitcoin not as a currency but as a payments protocol.”
Perhaps this is true. Yet from the original Nakamoto whitepaper, perhaps he too was a chartalist? Stating in section 1:
Commerce on the Internet has come to rely almost exclusively on financial institutions serving as trusted third parties to process electronic payments. While the system works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model. Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for non-reversible services. With the possibility of reversal, the need for trust spreads. Merchants must be wary of their customers, hassling them for more information than they would otherwise need. A certain percentage of fraud is accepted as unavoidable. These costs and payment uncertainties can be avoided in person by using physical currency, but no mechanism exists to make payments over a communications channel without a trusted party.
A payments rail, a currency, perhaps both?
Fun fact: the word “payment” appears 12 times in the whole white paper, just one time less than the word “trust” appears.
On page 29 they cite the Code of Hammurabi. I too think this is a good reference, having made a similar reference to the Code in Chapter 2 of my book last year.
On page 31 they write, “Today, China grapples with competition to its sovereign currency, the yuan, due both to its citizens’ demand for foreign national currencies such as the dollar and to a fledgling but potentially important threat from private, digital currencies such as bitcoin.”
That is a bit of a stretch. While Chinese policy makers do likely sweat over the creative ways residents breach and maneuver around capital controls, it is highly unlikely that bitcoin is even on the radar as a high level “threat.” There is no bitcoin merchant economy in China. The vast majority of activity continues to be related to mining and trading on exchanges, most of which is inflated by internal market making bots (e.g., the top three exchanges each run bots that dramatically inflate the volume via tape painting). And due to how WeChat and other social media apps in China frictionlessly connect residents with their mainland bank accounts, it is unlikely that bitcoin will make inroads in the near future.
On page 36 they write, “By 1973, once every country had taken its currency off the dollar peg, the pact was dead, a radical change.”
In point of fact, there are 23 countries that still peg their currency to the US dollar. Post-1973 saw a number of flexible and managed exchange rate regimes as well as notable events such as the Plaza Accord and Asian Financial Crisis (that impacted the local pegs).
On page 39 they write, “By that score, bitcoin has something to offer: a remarkable capacity to facilitate low-cost, near-instant transfer of value anywhere in the world.”
The point of contention here is the “low-cost” — something that the authors never really discuss the logistics of. They are aware of “seigniorage” and inflationary “block rewards” yet they do not describe the actual costs of maintaining the network which in the long run, the marginal costs equal the marginal value (MC=MV).
This is an issue that I tried to bring up with them at the Google Author Talk last month (I asked them both questions during the Q&A):
The problem for Vigna’s view, (starting around 59m) is that if the value of a bitcoin fell to $30, not only would the network collectively “be cheaper” to maintain, but also to attack.
On paper, the cost to successfully attack the network today by obtaining more than 50% of the hashrate at this $30 price point would be $2,250 per hour (roughly 0.5 x MC) or roughly an order of magnitude less than it does at today’s market price (although in practice it is a lot less due to centralization). Recall that the security of bitcoin was purposefully designed around proportionalism, that in the long run it costs a bitcoin to secure a bitcoin. We will talk about fees later at the end of next chapter.
On page 43, in the note at the bottom related to Ray Dillinger’s characterization that bitcoin is “highly inflationary” — Dillinger is correct in the short run. The money supply will increase by 11% alone this year. And while in the long run the network is deflationary (via block reward halving), the fact that the credentials to the bearer assets (bitcoins) are lost and destroyed each year results in a non-negligible amount of deflation.
For instance, in chapter 12 I noted some research: in terms of losing bitcoins, the chart below illustrates what the money supply looks like with an annual loss of 5% (blue), 1% (red) and 0.1% (green) of all mined bitcoins.
Source: Kay Hamacher and Stefan Katzenbeisser
In December 2011, German researchers Kay Hamacher and Stefan Katzenbeisser presented research about the impact of losing the private key to a bitcoin. The chart above shows the asymptote of the money supply (Y-axis) over time (X-axis).
According to Hamacher:
So to get rid of inflation, they designed the protocol that over time, there is this creation of new bitcoins – that this goes up and saturates at some level which is 21 million bitcoins in the end.
But that is rather a naïve picture. Probably you have as bad luck I have, I have had several hard drive crashes in my lifetime, and what happens when your wallet where your bitcoins are stored and your private key vanish? Then your bitcoins are probably still in the system so to speak, so they are somewhat identifiable in all the transactions but they are not accessible so they are of no economic value anymore. You cannot exchange them because you cannot access them. Or think more in the future, someone dies but his family doesn’t know the password – no economic value in those bitcoins anymore. They cannot be used for any exchange anymore. And that is the amount of bitcoins when just a fraction per year vanish for different fractions. So the blue curve is 5% of all the bitcoins per year vanish by whatever means there could be other mechanisms.
It is unclear exactly how many bitcoins can be categorized in such a manner today or what the decay rate is.
On page 45 the authors write, “Some immediately homed in on a criticism of bitcoin that would become common: the energy it would take to harvest “bitbux” would cost more than they were worth, not to mention be environmentally disastrous.”
While I am unaware of anyone who states that it would cost more than what they’re worth, as stated in Appendix B and in Chapter 3 (among many other places), the network was intentionally designed to be expensive, otherwise it would be “cheap to attack.” And those costs scale in proportion to the token value.
As noted a few weeks ago:
For instance, last year O’Dwyer and Malone found that Bitcoin mining consumes roughly the same amount of energy as Ireland does annually. It is likely that their estimate was too high and based on Dave Hudson’s calculations closer to 10% of Ireland’s energy consumption.23 Furthermore, it has likely declined since their study because, as previously explored in Appendix B, this scales in proportion with the value of the token which has declined over the past year.
The previous post looked at bitcoin payments processed by BitPay and found that as an aggregate the above-board activity on the Bitcoin network was likely around $350 million a year. Ireland’s nominal GDP is expected to reach around $252 billion this year. Thus, once Hudson’s estimates are integrated into it, above-board commercial bitcoin activity appears to be about two orders of magnitude less than what Ireland produces for the same amount of energy.
Or in other words, the original responses to Nakamoto six and a half years ago empirically was correct. It is expensive and resource intensive to maintain and it was designed to be so, otherwise it would be easy to attack, censor and modify the history of votes.
Starting on page 56 they describe Mondex, Secure Electronic Transaction (SET), Electronic Monetary System, Citi’s e-cash model and a variety of other digital dollar systems that were developed during the 1990s. Very interesting from a historical perspective and it would be curious to know what more of these developers now think of cryptocurrency systems. My own view, is that the middle half of Chapter 2 is the best part of the book: very well researched and well distilled.
On page 64 they write:
[T]hat Nakamoto launched his project with a reminder that his new currency would require no government, no banks and no financial intermediaries, “no trusted third party.”
In theory this may be true, but in practice, the Bitcoin network does not natively provide any of the services banks do beyond a lock box. There is a difference between money and the cornucopia of financial instruments that now exist and are natively unavailable to Bitcoin users without the use of intermediaries (such as lending).
On page 66 they write, “He knew that the ever-thinning supply of bitcoins would eventually require an alternative carrot to keep miners engaged, so he incorporated a system of modest transaction fees to compensate them for the resources they contributed. These fees would kick in as time went on and as the payoff for miners decreased.”
Above is a chart visualizing fees to miners denominated in USD from January 2009 to May 17, 2015. Perhaps the fees will indeed increase to replace block rewards, or conversely, maybe as VC funding declines in the coming years, the companies that are willing and able to pay fees for each transaction declines.
On page 67, the authors introduce us to Laszlo Hanyecz, a computer programmer in Florida who according to the brief history of Bitcoin lore, purchased two Papa John’s pizzas for 10,000 bitcoins on May 22, 2010 (almost five years ago to the day). He is said to have sold 40,000 bitcoins in this manner and generated all of the bitcoins through mining. He claims to be the first person to do GPU mining, ramping up to “over 800 times” of a CPU; and during this time “he was getting about half of all the bitcoins mined.” According to him, he originally used a Nvidia 9800 GTX+ and later switched to 2 AMD Radeon 5970s. It is unclear how long he mined or when he stopped.
In looking at the index of his server, there are indeed relevant OpenCL software files. If this is true, then he beat ArtForz to GPU mining by at least two months.
On page 77 they write, “Anybody can go on the Web, download the code for no cost, and start running it as a miner.”
While technically this is true, that you can indeed download the Satoshi Bitcoin core client for free, restated in 2015 it is not viable for hoi polloi. In practice you will not generate any bitcoins solo-mining on a desktop machine unless you do pooled mining circa 2011. Today, even pooled mining with the best Xeon processors will be unprofitable. Instead, the only way to generate enough funds to cover both the capital expenditures and operating expenditures is through the purchase of single-use hardware known as an ASIC miner, which is a depreciating capital good. Mining has been beyond the breakeven reach of most non-savvy home users for two years now, not to mention those who live in developing countries with poor electrical infrastructure or uncompetitive energy rates. It is unlikely that embedded mining devices will change that equation due to the fact that every additional device increases the difficultly level whilst the device hashrate remains static.
This ties in with what the authors also wrote on page 77, “You don’t buy bitcoin’s software as you would other products, which means you’re not just a customer. What’s more, there’s no owner of the software — unlike, say, PayPal, which is part of eBay.”
This is a bit misleading. In order to use the Bitcoin network, users must obtain bitcoins somehow. And in practice that usually occurs through trusted third parties such as Coinbase or Xapo which need to identify you via KYC/AML processes. So while in 2009 their quote could have been true, in practice today that is largely untrue for most new participants — someone probably owns the software and your personal data. In fact, a germane quote on reddit last week stated, “Why don’t you try using Bitcoin instead of Coinbase.”
Furthermore, the lack of “ownership” of Bitcoin is dual-edged as there are a number of public goods problems with maintaining development that will be discussed later.
On page 87 they describe Blockchain.info as a “high-profile wallet and analytics firm.” I will come back to “wallets” later. Note: most of these “wallets” are likely throwaway, temp wallets used to move funds to obfuscate provenance through the use of Shared Coin (one of the ways Blockchain.info generates revenue is by operating a mixer).
Overall Chapter 3 was also fairly informative. The one additional quibble I have is that Austin and Beccy Craig (the story at the end) were really only able to travel the globe and live off bitcoins for 101 days because they had a big cushion: they had held a fundraiser that raised $72,995 of additional capital. That is enough money to feed and house a family in a big city for a whole year, let alone go globe trotting for a few months.
On page 99 they describe seven different entities that have access to credit card information when you pay for a coffee at Starbucks manually. Yet they do not describe the various entities that end up with the personal information when signing up for services such as Coinbase, ChangeTip, Circle and Xapo or what these depository institutions ultimately do with the data (see also Richard Brown’s description of the payment card system).
When describing cash back rewards that card issuers provide to customers, on page 100 they write, “Still it’s an illusion to think you are not paying for any of this. The costs are folded into various bank charges: card issuance fees, ATM fees, checking fees, and, of course, the interest charged on the millions of customers who don’t pay their balances in full each month.”
Again, to be even handed they should also point out all the fees that Coinbase charges, Bitcoin ATMs charge and so forth. Do any of these companies provide interest-bearing accounts or cash-back rewards?
On page 100 they also stated that, “Add in the cost of fraud, and you can see how this “sand in the cogs” of the global payment system represents a hindrance to growth, efficiency, and progress.”
That seems a bit biased here. And my statement is not defending incumbents: global payment systems are decentralized yet many provide fraud protection and insurance — the very same services that Bitcoin companies are now trying to provide (such as FDIC insurance on fiat deposits) which are also not free.
On page 100 they also write, “We need these middlemen because the world economy still depends on a system in which it is impossible to digitally send money from one person to another without turning to an independent third party to verify the identity of the customer and confirm his or her right to call on the funds in the account.”
Again, in practice, this is now true for Bitcoin too because of how most adoption continues to take place on the edges in trusted third parties such as Coinbase and Circle.
On page 101 they write:
In letting the existing system develop, we’ve allowed Visa and MasterCard to form a de facto duopoly, which gives them and their banking partners power to manipulate the market, says Gil Luria, an analyst covering payment systems at Wedbush Securities. Those card-network firms “not only get to extract very significant fees for themselves but have also created a marketplace in which banks can charge their own excessive fees,” he says.
Why is it wrong to charge fees for a service? What is excessive? I am certainly not defending incumbents or regulatory favoritism but it is unclear how Bitcoin institutions in practice — not theory — actually are any different.
And, the cost per transaction for Bitcoin is actually quite high (see chart below) relative to these other systems due to the fact that Bitcoin also tries to be a seigniorage system, something that neither Visa or MasterCard do.
On page 102 when talking about MasterCard they state, “But as we’ve seen, that cumbersome system, as it is currently designed, is tightly interwoven into the traditional banking system, which always demands a cut.”
The whole page actually is a series of apples-and-oranges comparisons. Aside from settlement, the Bitcoin network does not provide any of the services that they are comparing it to. There is nothing in the current network that provides credit/lending services whereas the existing “cumbersome” system was not intentionally designed to be cumbersome, but rather is intertwined and evolved over decades so that customers can have access to a variety of otherwise siloed services. Again, this is not to say the situation cannot be improved but as it currently exists, Bitcoin does not provide a solution to this “cumbersome” system because it doesn’t provide similar services.
On page 102 and 103 they write about payment processors such as BitPay and Coinbase, “These firms touted a new model to break the paradigm of merchants’ dependence on the bank-centric payment system described above. These services charged monthly fees that amounted to significantly lower transaction costs for merchants than those charged in credit-card transactions and delivered swift, efficient payments online or on-site.”
Except this is not really true. The only reason that both BitPay and Coinbase are charging less than other payment processors is that VC funding is subsidizing it. These companies still have to pay for customer service support and fraud protection because customer behavior in aggregate is the same. And as we have seen with BitPay numbers, it is likely that BitPay’s business model is a losing proposition and unsustainable.
On page 103 they mention some adoption metrics, “The good news is found in the steady expansion in the adoption of digital wallets, the software needed to send and receive bitcoins, with Blockchain and Coinbase, the two biggest providers of those, on track to top 2 million unique users each at the time of the writing.”
This is at least the third time they talk about wallets this way and is important because it is misleading, I will discuss in-depth later.
Continuing they write that:
Blockchain cofounder Peter Smith says that a surprisingly large majority of its accounts — “many more than you would think,” he says cryptically — are characterized as “active.”
This is just untrue and should have been pressed by the authors. Spokesman from Blockchain.info continue to publish highly inflated numbers. For instance in late February 2015, Blockchain.info claimed that “over $270 million in bitcoin transactions occurred via its wallets over the past seven days.”
This is factually untrue. As I mentioned three months ago:
Organ of Corti pointed out that the 7 day average was indeed ~720,000 bitcoins in total output volume (thus making) the weekly volume would be about “5e06 btc for the network.”
Is it valid to multiply the total output volume by USD (or euros or yen)? No.
Why not? Because most of this activity is probably a combination of wallet shuffling, laundering and mixing of coins (e.g., use of SharedSend and burner wallets) or any number of superfluous activity. It was not $270 million of economic trade.
Blockchain.info’s press release seems to be implying that economic trade is taking place, in which all transactions are (probably) transactions to new individuals when in reality it could simply be a lot of “change” address movement. And more to the point, the actual internal volume looks roughly the same as has been the past few months (why issue a press release now?).
Continuing on page 103 they write, “For the first eight months months of 2014, around $50 million per day was passing thought the bitcoin network (some of which was just “change” that bitcoin transactions create as an accounting measure)…”
There is a small typo above (in bold) but the important part is the estimate of volume. There is no public research showing a detailed break down of average volume of economic activity. Based on a working paper I published four months ago, it is fairly clear that this figure is probably in the low millions USD at most. Perhaps this will change in the future.
On page 106 they write about Circle and Xapo:
For now, these firms make no charge to cover costs of insurance and security, betting that enough customers will be drawn to them and pay fees elsewhere — for buying and selling bitcoins, for example — or that their growing popularity will allow them to develop profitable merchant-payment services as well. But over all, these undertaking must add costs back into the bitcoin economy, not to mention a certain dependence on “trusted third parties.” It’s one of many areas of bitcoin development — another is regulation — where some businessmen are advocating a pragmatic approach to bolstering public confidence, one that would necessitate compromises on some of the philosophical principles behind a model of decentralization. Naturally, this doesn’t sit well with bitcoin purists.
While Paul Vigna may not have written this, he did say something very similar at the Google Author Talk event (above in the video).
The problem with this view is that it is a red herring: this has nothing to do with purism or non-purism.
The problem is that Bitcoin’s designer attempted to create a ‘permissionless’ system to accommodate pseudonymous actors. The entire cost structure and threat model are tied to this. If actors are no longer pseudonymous, then there is no need to have this cost structure, or to use proof-of-work at all. In fact, I would argue that if KYC/KYM (Know Your Miner) are required then a user might just as well use a database or permissioned system. And that is okay, there are businesses that will be built around that.
This again has nothing to do with purism and everything to do with the costs of creating a reliable record of truth on a public network involving unknown, untrusted actors. If any of those variables changes — such as adding real-world identity, then from a cost perspective it makes little sense to continue using the modified network due to the intentionally expensive proof-of-work.
On page 107 they talk about bitcoin price volatility discussing the movements of gasoline. The problem with this analogy is that no one is trying to use gasoline as money. In practice consumers prefer purchasing power stability and there is no mechanism within the Bitcoin network that can provide this.
The three slides above are from a recent presentation from Robert Sams. Sams previously wrote a short paper on “Seigniorage Shares” — an endogenous way to rebase for purchasing power stability within a cryptocurrency.
Bitcoin’s money supply is perfectly inelastic therefore the only way to reflect changes in demand is through changes in price. And anytime there are future expectations of increased or decreased utility, this is reflected in prices via volatility.
Oddly however, on page 110, they write, “A case can be made that bitcoin’s volatility is unavoidable for the time being.”
Yet they do not provide any evidence — aside from feel good “Honey Badger” statements — for how bitcoin will somehow stabilize. This is something the journalists should have drilled down on, talking to commodity traders or some experts on fuel hedging strategies (which is something airline companies spend a great deal of time and resources with).
Instead they cite Bobby Lee, CEO of BTC China and Gil Luria once again. Lee states that “Once its prices has risen far enough and bitcoin has proven itself as a store of value, then people will start to use it as a currency.”
This is a collective action problem. Because all participants each have different time preferences and horizons — and are decentralized — this type of activity is actually impossible to coordinate, just ask Josh Garza and the $20 Paycoin floor. This also reminds me of one of my favorite comments on reddit: “Bitcoin will stabilize in price then go to the moon.”
The writers then note that, “Gil Luria, the Wedbush analyst, even argues that volatility is a good thing, on the grounds that it draws profit-seeking traders into the marketplace.”
But just because you have profit-seeking traders in the market place does not mean volatility disappears.

It bears mentioning that Ferdinando Ametrano has also described this issue in depth most recently in a presentation starting on slide 15.
Continuing on page 111, the writers note that:
Over time, the expansion of these desks, and the development of more and more sophisticated trading tools, delivered so much liquidity that exchange rates became relatively stable. Luria is imagining a similar trajectory for bitcoin. He says bitcoiners should be “embracing volatility,” since it will help “create the payment network infrastructure and monetary base” that bitcoin will need in the future.
There are two problems with Luria’s argument:
1) As noted above, this does not happen with any other commodity and historically nothing with a perfectly inelastic supply
2) Empirically, as described by Wences Casares above, nearly all the bitcoins held at Xapo (and likely other “hosted wallets”) are being held as investments. This reduces liquidity which translates into volatility due to once again the inability to slowly adjust the supply relative to the shifts in demand. This ties into a number of issues discussed in, What is the “real price” of bitcoin? that are worth revisiting.
Also on page 111, they write that “the exchange rate itself doesn’t matter.”
Actually it does. It directly impacts two things:
1) outside perception on the health of Bitcoin and therefore investor interest (just talk to Buttercoin);
2) on a ten-minute basis it impacts the bottom line of miners. If prices decline, so to is the incentive to generate proof-of-work. Bankruptcy, as CoinTerra faces, is a real phenomenon and if prices decline very quickly then the security of the network can also be reduced due to less proof-of-work being generated
Continuing on page 111, “It’s expected that the mirror version of this will in time be set up for consumers to convert their dollars into bitcoins, which will then immediately be sent to the merchant. Eventually, we could all be blind to these bitcoin conversions happening in the middle of all our transactions.”
It’s unfortunate that they do not explain how this will be done without a trusted third party, or why this process is needed. What is the advantage of going from USD-> paying a conversion fee -> BTC -> conversion fee -> back into USD? Why not just spend USD and cut out the Bitcoin middleman?
Lastly on page 111, “Still, someone will have to absorb the exchange-rate risk, if not the payment processors, then the investors with which they trade.”
The problem with this is that its generally not in the mandate or scope of most VC firms to purchase commodities or currencies directly. In fact, they may even need some kind of license to do so depending on the jurisdiction (because it is a foreign exchange play). Yet expecting the payment processors to shoulder the volatility is probably a losing proposition: in the event of a protracted bear market how many bitcoins at BitPay — underwater or not — will need to be liquidated to pay for operating costs?4
On page 112 they write, ‘Bitcoin has features from all of them, but none in entirety. So, while it might seem unsatisfying, our best answer to the question of whether cryptocurrency can challenge the Visa and MasterCard duopoly is, “maybe, maybe not.”
On the face of it, it is a safe answer. But upon deeper inspection we can probably say, maybe not. Why? Because for Bitcoin, once again, there is no native method for issuing credit (which is what Visa/MasterCard do with what are essentially micro-loans).
For example, in order to natively add some kind of lending facility within the Bitcoin network a new “identity” system would need to be built and integrated (to enable credit checks) — yet by including real-world “identity” it would remove the pseudonymity of Bitcoin while simultaneously maintaining the same costly proof-of-work Sybil protection. This is again, an unnecessary cost structure entirely and positions Bitcoin as a jack-of-all-trades-but-master-of-none. Why? Again recall that the cost structure is built around Dynamic Membership Multi-Party Signature (DMMS); if the signing validators are static and known you might as well use a database or permissioned ledgers.
Or as Robert Sams recently explained, if censorship resistance is co-opted then the reason for proof-of-work falls to the wayside:
Now, I am sure that the advocates of putting property titles on the bitcoin blockchain will object at this point. They will say that through meta protocols and multi-key signatures, third party authentication of transaction parties can be built-in, and we can create a registered asset system on top of bitcoin. This is true. But what’s the point of doing it that way? In one fell swoop a setup like that completely nullifies the censorship resistance offered by the bitcoin protocol, which is the whole raison d’etre of proof-of-work in the first place! These designs create a centralised transaction censoring system that imports the enormous costs of a decentralised one built for censorship-resistance, the worst of both worlds.
If you are prepared to use trusted third parties for authentication of the counterparts to a transaction, I can see no compelling reason for not also requiring identity authentication of the transaction validators as well. By doing that, you can ditch the gross inefficiencies of proof-of-work and use a consensus algorithm of the one-node-one-vote variety instead that is not only thousands of times more efficient, but also places a governance structure over the validators that is far more resistant to attackers than proof-of-work can ever be.
On page 113, they write, “the government might be able to take money out of your local bank account, but it couldn’t touch your bitcoin. The Cyprus crisis sparked a stampede of money into bitcoin, which was now seen as a safe haven from the generalized threat of government confiscation everywhere.”
In theory this may be true, but in practice, it is likely that a significant minority — if not majority — of bitcoins are now held in custody at depository institutions such as Xapo, Coinbase and Circle. And these are not off-limits to social engineering. For instance, last week an international joint-task force confiscated $80,000 in bitcoins from dark web operators. The largest known seizure in history were 144,000 bitcoins from Ross Ulbricht (Dread Pirate Roberts) laptop.
Similarly, while it probably is beyond the scope of their book, it would have been interesting to see a survey from Casey and Vigna covering the speculators during this early 2013 time frame. Were the majority of people buying bitcoins during the “Cyprus event” actually worried about confiscation or is this just something that is assumed? Fun fact: the largest transaction to BitPay of all time was on March 25, 2013 during the Cyprus event, amounting to 28,790 bitcoins.
On page 114, the writers for the first time (unless I missed it elsewhere), use the term “virtual currency.” Actually, they quote FinCEN director Jennifer Calvery who says that FincCEN, “recognizes the innovation virtual currencies provide , and the benefits they might offer society.”
Again recall that most fiat currencies today are already digitized in some format — and they are legal tender. In contrast, cryptocurrencies such as bitcoin are not legal tender and are thus more accurately classified as virtual currencies. Perhaps that will change in the future.
On page 118 they note that, “More and more people opened wallets (more than 5 million as of this writing).”
I will get to this later. Note that on p. 123 they say Coupa Cafe has a “digital wallet” a term used throughout the entire book.
On page 124, “Bitcoins exist only insofar as they assign value to a bitcoin address, a mini, one-off account with which people and firms send and receive the currency to and from other people’s firms’ addresses.”
This is actually a pretty concise description of best-practices. In reality however, many individuals and organizations (such as exchanges and payment processors) reuse addresses.
Continuing on page 124, “This is an important distinction because it means there’s no actual currency file or document that can be copied or lost.”
This is untrue. In terms of security, the hardest and most expensive part in practice is securing the credentials — the private key that controls the UTXOs. As Stefan Thomas, Jason Whelan (p. 139) and countless other people on /r/sorryforyourloss have discovered, this can be permanently lost. Bearer assets are a pain to secure, hence the re-sprouting of trusted third parties in Bitcoinland.
One small nitpick in the note at the bottom of page 125, “Sometimes the structure of the bitcoin address network is such that the wallet often can’t send the right amount in one go…” — note that this ‘change‘ is intentional (and very inconvenient to the average user).
Another nitpick on page 128, “Each mining node or computer gathers this information and reduces it into an encrypted alphanumeric string of characters known as a hash.”
There is actually no encryption used in Bitcoin, rather there are some cryptographic primitives that are used such as key signing but this is not technically called encryption (the two are different).
On page 130, I thought it was good that they explained where the term nonce was first used — from Lewis Carroll who created the word “frabjous” and described it as a nonce word.
On page 132, in describing proof-of-work, “While that seems like a mammoth task, these are high-powered computers; it’s not nearly as taxing as the nonce-creating game and can be done relatively quickly and easily.”
They are correct in that something as simple as a Pi computer can and is used as the actual transaction validating machine. Yet, at one point in 2009, this bifurcation did not exist: a full-node was both a miner and a hasher. Today that is not the case and we technically have about a dozen or so actual miners on the network, the rest of the machines in “farms” just hash midstates.
On page 132, regarding payment processors accepting zero-confirmation transactions, “They do this because non-confirmations — or the double-spending actions that lead to them — are very rare.”
True they are very rare today in part because there are very few incentives to actually try and double-spend. Perhaps that will change in the future with new incentives to say, double-spend watermarked coins from NASDAQ.
And if payment processors are accepting zero confirmations, why bother using proof-of-work and confirmations at all? Just because a UTXO is broadcast does not mean it will not be double-spent let alone confirmed and packaged into a block. See also replace-by-fee proposal.
Small note on page 132, “the bitcoin protocol won’t let it use those bitcoins in a payment until a total of ninety-nine additional blocks have been built on top its block.”
Sometimes it depends on the client and may be up to 120 blocks altogether, not just 100.
On page 133 they write, “Anyone can become a miner and is free to use whatever computing equipment he or she can come up with to participate.”
This may have been the case in 2009 but not true today. In order to reduce payout variance, the means of production as it were, have gravitated towards large pools of capital in the form of hashing farms. See also: The Gambler’s Guide to Bitcoin Mining.
On page 135 they write, “Some cryptocurrency designers have created nonprofit foundations and charged them with distributing the coins based on certain criteria — to eligible charities, for example. But that requires the involvement of an identifiable and trusted founder to create the foundation.”
The FinCEN enforcement action and fine on Ripple Labs may put a kibosh on this in the future. Why? If organizations that hand out or sell coins are deemed under the purview of the Bank Secrecy Act (BSA) it is clear that most, if not all, crowdfunding or initial coin offerings (ICO) are violating this by not implementing KYC/AML requirements on participants or filing SARs.
On page 136 they write, “Both seigniorage and transaction fees represent a transfer of value to those running the network. Still, in the grand scheme of things, these costs are far lower than anything found in the old system.”
This is untrue and an inaccurate comparison. We know that at the current bitcoin price of $240 it costs roughly $315 million to operate the network for the entire year. If bitcoin-based consumer spending patterns hold up and reflect last years trends seen by BitPay, then roughly $350 million will be spent through payment processors, nearly half of which includes mining payouts.
Or in other words, for roughly every dollar spent on commerce another dollar is spent securing it. This is massive oversecurity relative to the commerce involve. Neither Saudi Arabia or even North Korea spend half of, let alone 100% of their GDP on military expenditures (yet).
Small nitpick on page 140, Butterfly Labs is based in Leawood, Kansas not Missouri (Leawood is on the west side of the dividing line).
I think the story of Jason Whelan is illuminating and could help serve as a warning guide to anyone wanting to splurge on mining hardware.
For instance on page 141, “And right from the start Whelan face the mathematical reality that his static hashrate was shrinking as a proportion of the ever-expanding network, whose computing power was by then almost doubling every month.”
Not only was this well-written but it does summarize the problem most new miners have when they plan out their capital expenditures. It is impossible to know what the network difficulty will be in 3 months yet what is known is that even if you are willing to tweak the hardware and risk burning out some part of your board, your hashrate could be diluted by faster more efficient machines. And Whelan found out the hard way that he might as well bought and held onto bitcoins than mine. In fact, Whelan did just about everything the wrong way, including buying hashing contracts with cloud miners from “PBCMining.com” (a non-functioning url).
On page 144 the authors discussed the mining farms managed by now-defunct CoinTerra:
With three in-built high-powered fans running at top speed to cool the rig while its internal chi races through calculations, each unit consumes two kilowatts per hour, enough power to run an ordinary laptop for a month. That makes for 20 kWh per tower, about ten times the electricity used for the same space by the neighboring server of more orthodox e-commerce firms.
As noted in Chapter 2 above, this electricity has to be “wasted.” Bitcoin was designed to be “inefficient” otherwise it would be easy to attack and censor. And in the future, it cannot become more “efficient” — there is no free lunch when it comes to protecting it. It also bears mentioning that CoinTerra was sued by its utility company in part for the $12,000 a day in electrical costs that were not being paid for.
On page 145 they wrote that as of June 2014, “By that time, the network, which was then producing 88,000 trillion hashes every second, had a computing power six thousand times the combined power of the world’s top five hundred supercomputers.”
This is not a fair comparison. ASIC miners can do one sole function, they are unable to do anything aside from reorganize a few fields (such as date and nonce) with the aim of generating a new number below a target number. They cannot run MS Office, Mozilla Firefox and more sobering: they cannot even run a Bitcoin client (the Pi computer run by the pool runs the client).
In contrast, in order to be recognized as a Top 500 computer, only general purpose machines capable of running LINXPACK are considered eligible. The entire comparison is apples-to-oranges.
On page 147 the authors described a study from Guy Lane who used inaccurate energy consumption data from Blockchain.info. And then they noted that, “So although the total consumption is significantly higher than the seven-thousand-home estimate, we’re a long way from bitcoin’s adding an entire country’s worth of power consumption to the world.”
This is not quite true. As noted above in the notes of Chapter 2 above, based on Dave Hudson’s calculations the current Bitcoin network consumes the equivalent of about 10% of Ireland’s annual energy usage yet produces two orders of magnitude less economic activity. If the price of bitcoin increases so to does the amount of energy miners are willing to expend to chase after the seigniorage. See also Appendix B.
On page 148 they write that:
For one, power consumption must be measured against the value of validating transactions in a payment system, a social service that gold mining has never provided. Second, the costs must be weighed against the high energy costs of the alternative, traditional payment system, with its bank branches, armored cars, and security systems. And finally, there’s the overriding incentive for efficiency that the profit motive delivers to innovators, which is why we’ve seen such giant reductions in power consumption for the new mining machines. If power costs make mining unprofitable, it will stop.
First of all, validation is cheap and easy, as noted above it is typically done with something like a Pi computer. Second, they could have looked into how much real commerce is taking place on the chain relative to the costs of securing it so the “social service” argument probably falls flat at this time.
Thirdly, the above “armored cars and security systems” is not an apples-to-apples comparison. Bitcoin does not provide any banking service beyond a lock box, it does not provide for home mortgages, small business loans or mezzanine financing. The costs for maintaining those services in the traditional world do not equate to MC=MV as described at the end of Chapter 1 notes.
Fourthly, they ignore the Red Queen effect. If a new hashing machine is invented and consumes half as much energy as before then the farm owner will just double the amount of machines and the net effect is the same as before. This happens in practice, not just in theory, hence the reason why electrical consumption has gone up in aggregate and not down.
On page 149 they write, “But the genius of the consensus-building in the bitcoin system means such forks shouldn’t be allowed to go on for long. That’s because the mining community works on the assumption that the longest chain is the one that constitutes consensus.”
That’s not quite accurate. Each miner has different incentives. And, as shown empirically with other altcoins, forks can reoccur frequently without incentives that align. For now, some incentives apparently do. But that does not mean that in the future, if say watermarked coins become more common place, that there will not be more frequent forks as certain miners attempt to double-spend or censor such metacoins.
Ironically on page 151 the authors describe the fork situation of March 2013 and describe the fix in which a few core developers convince Mark Karpeles (who ran Mt. Gox) to unilaterally adopt one specific fork. This is not trustless.
On page 151 they write, “That’s come to be known as a 51 percent attack. Nakamoto’s original paper stated that the bitcoin mining network could be guaranteed to treat everyone’s transactions fairly and honestly so long as no single miner or mining group owned more than 50 percent of the hashing power.”
And continuing on page 153, “So, the open-source development community is now looking for added protections against selfish mining and 51 percent attacks.”
While they do a good job explaining the issue, they don’t really discuss how it is resolved. And it cannot be without gatekeepers or trusted hardware. For instance, three weeks ago there was a good reddit thread discussing one of the problems of Andreas Antonopolous’ slippery slope view that you could just kick the attackers off the network. First, there is no quick method for doing so; second, by blacklisting them you introduce a new problem of having the ability to censor miners which would be self-defeating for such a network as it introduces a form of trust into an expensive cost structure of trust minimization.
On page 152 they cite a Coinometrics number, “in the summer of 2014 the cost of the mining equipment and electricity required for a 51 percent attack stood at $913 million.”
This is a measurement of maximum costs based on hashrate brute force — a Maginot Line attack. In practice it is cheaper to do via out of band attacks (e.g., rubber hose cryptanalysis). There are many other, cheaper ways, to attack the P2P network itself (such as Eclipse attacks).
On page 154 when discussing wealth disparity in Bitcoin they write, “First, some perspective. As a wealth-gap measure, this is a lousy one. For one, addresses are not wallets. The total number of wallets cannot be known, but they are by definition considerably fewer than the address tally, even though many people hold more than one.”
Finally. So the past several chapters I have mentioned I will discuss wallets at some length. Again, the authors for some reason uncritically cite the “wallet numbers” from Blockchain.info, Coinbase and others as actual digital wallets. Yet here they explain that these metrics are bupkis. And they are. It costs nothing to generate a wallet and there are scripts you can run to auto generate them. In fact, Zipzap and many others used to give every new user a Blockchain.info wallet por gratis.
And this is problematic because press releases from Xapo and Blockchain.info continually cite a number that is wholly inaccurate and distorting. For instance Wences Casares said in a presentation a couple months ago that there were 7 million users. Where did that number come from? Are these on-chain privkey holders? Why are journalists not questioning these claims? See also: A brief history of Bitcoin “wallet” growth.
On page 154 they write, “These elites have an outsize impact on the bitcoin economy. They have a great interest in seeing the currency succeed and are both willing and able to make payments that others might not, simply to encourage adoption.”
Perhaps this is true, but until there is a systematic study of the conspicuous consumption that takes place, it could also be the case that some of these same individuals just have an interest in seeing the price of bitcoin rise and not necessarily be widely adopted. The two are not mutually exclusive.
On page 155 and 156 they describe the bitsat project, to launch a full node into space which is aimed “at making the mining network less concentrated.”
Unfortunately these types of full nodes are not block makers. Thus they do not actually make the network less concentrated, but only add more propagating nodes. The two are not the same.
On page 156 they describe some of the altcoin projects, “They claim to take the good aspects of bitcoin’s decentralized structure but to get ride of its negative elements, such as the hashing-power arms race, the excessive use of electricity, and the concentration of industrialized mining power.”
I am well aware of the dozens various coin projects out there due to work with a digital asset exchange over the past year. Yet fundamentally all of the proof-of-work based coins end up along the same trend line, if they become popular and reach a certain level of “market cap” (an inaccurate term) specialized chips are designed to hash it. And the term “excessive” energy related to proof-of-work is a bit of a non-starter. Ignoring proof-of-stake systems, if it becomes less energy intensive to hash via POW, then it also becomes cheaper to attack. Either miners will add more equipment or the price has dropped for the asset and it is therefore cheaper to attack.
On page 157 regarding Litecoin they write that, “Miners still have an incentive to chase coin rewards, but the arms race and the electricity usage aren’t as intense.”
That’s untrue. Scrypt (which is used instead of Hashcash) is just as energy intensive. Miners will deploy and utilize energy in the same patterns, directly in proportion to the token price. The difference is memory usage (Litecoin was designed to be more memory intensive) but that is unrelated to electrical consumption.
Continuing, “Litecoin’s main weakness is the corollary of its strength: because it’s cheaper to mine litecoins and because scrypt-based rigs can be used to mine other scrypt-based altcoins such as dogecoin, miners are less heavily invested in permanently working its blockchain.”
This is untrue. Again, Litecoin miners will in general only mine up to the point where it costs a litecoin to make a litecoin. Obviously there are exceptions to it, but in percentage terms the energy usage is the same.
Continuing, “Some also worry that scrypt-based mining is more insecure, with a less rigorous proof of work, in theory allowing false transactions to get through with incorrect confirmations.”
This is not true. The two difference in security are the difficulty rating and block intervals. The higher the difficulty rating, the more energy is being used to bury blocks and in theory, the more secure the blocks are from reversal. The question is then, is 2.5 minutes of proof-of-work as secure as burying blocks every 10 minutes? Jonathan Levin, among others, has written about this before.
Small nitpick on page 157, fairly certain that nextcoin should be referred to as NXT.
On page 158 they write:
If bitcoin is to scale up, it must be upgraded sot hat nodes, currently limited to one megabyte of data per ten-minute block, are free to process a much larger set of information. That’s not technically difficult; but it would require miners to hash much larger blocks of transactions without big improvements in their compensation. Developers are currently exploring a transaction-fee model that would provide fairer compensation for miners if the amount of data becomes excessive.
This is not quite right. There is a difference between block makers (pools) and hashers (mining farms). The costs for larger blocks would impact block makers not hashers, as they would need to upgrade their network facilities and local hard drive. This may seem trivial and unimportant, but Jonathan Levin’s research, as well as others suggest that block sizes does in fact impact orphan rates.5 It also impacts the amount of decentralization within the network as larger blocks become more expensive to propagate you will likely have fewer nodes. This has been the topic of immense debate over the past several weeks on social media.
Also on page 158 they write:
The laboratory used by cryptocurrency developers, by contrast, is potentially as big as the world itself, the breadth of humanity that their projects seek to encompass. No company rulebook or top-down set of managerial instructions keeps people’s choice in line with a common corporate objective. Guiding people to optimal behavior in cryptocurrencies is entirely up to how the software is designed to affect human thinking, how effectively its incentive systems encourage that desired behavior
This is wishful thinking and probably unrealistic considering that Bitcoin development permanently suffers from the tragedy of the commons. There is no CEO which is both good and bad.
For example, directions for where development goes is largely based on two things:
how many upvotes your comment has on reddit (or how many retweets it gets on Twitter)
your status is largely a function of how many times Satoshi Nakamoto responded to you in email or on the Bitcointalk forum creating a permanent clique of “early adopters” whose opinions are the only valid ones (see False narratives)
This is no way to build a financial product. Yet this type of lobbying is effectively how the community believes it will usurp well-capitalized private entities in the payments space.
I’ve said it before and I will say it again. There is a reason why Developers should not be in control of product development priorities, naming, feature lists, or planning for a product. That is the job of the sales, marketing, and product development teams who actually interface with the customer. They are the ones who do the research and know what’s needed for a product. They are the ones who are supposed to decide what things are called, what features come next, and how quickly shit gets out the door.
Bitcoin has none of that. You’ve got a Financial product, being created for a financial market, by a bunch of developers with no experience in finance, and (more importantly) absolutely no way for the market to have any input or control over what gets done, or what it’s called. That is crazy to me.
Luke is a perfect example of why you don’t give developers control over anything other than the structure of the code.
They are not supposed to be making product development decisions. They are not supposed to be naming anything. And they definitely are not supposed to be deciding “what comes next” or how quickly things get done. In any other company, this process would be considered suicide.
Yet for some reason this is considered to be a feature rather than a bug (e.g., “what is your Web of Trust (WoT) number?”).
On page 159 they write, “The vital thing to remember is that the collective brainpower applied to all the challenges facing bitcoin and other cryptocurrencies is enormous. Under the open-source, decentralized model, these technologies are not hindered by the same constraints that bureaucracies and stodgy corporations face.”
So, what is the Terms of Service for Bitcoin? What is the customer support line? There isn’t one. Caveat emptor is pretty much the marketing slogan and that is perfectly fine for some participants yet expecting global adoption without a “stodgy” “bureaucracy” that helps coordinate customer service seems a bit of a stretch.
And just because there is some avid interest from a number of skilled programmers around the world does not mean public goods problems surrounding development will be resolved. For reference: there were over 5000 co-authors on a recent physics paper but that doesn’t mean their collective brain power will quickly resolve all the open questions and unsolved problems in physics.
Small nitpick on page 160, “Bitcoin was born out of a crypto-anarchist vision of a decentralized government-free society, a sort of encrypted, networked utopia.”
On page 162 they write, “Before we get too carried away, understand this is still early days.”
That may be the case. Perhaps decentralized cryptocurrencies like Bitcoin are not actually the internet in the early 1990s like many investors claim but rather the internet in the 1980s when there were almost no real use-cases and it is difficult to use. Or 1970s. The problem is no one can actually know the answer ahead of time.
And when you try to get put some milestone down on the ground, the most ardent of enthusiasts move the goal posts — no comparisons with existing tech companies are allowed unless it is to the benefit of Bitcoin somehow. I saw this a lot last summer when I discussed the traction that M-Pesa and Venmo had.
A more recent example is “rebittance” (a portmanteau of “bitcoin” and “remittance”). A couple weeks ago Yakov Kofner, founder of Save On Send, published a really good piece comparing money transmitter operators with bitcoin-related companies noting that there currently is not much meat to the hype. The reaction on reddit was unsurprisingly fist-shaking Bitcoin rules, everyone else drools.
With Yakov Kofner (CEO Save On Send)
When I was in NYC last week I had a chance to meet with him twice. It turns out that he is actually quite interested in Bitcoin and even scoped out a project with a VC-funded Bitcoin company last year for a consumer remittances product.
But they decided not to build and release it for a few reasons: 1) in practice, many consumers are not sensitive enough to a few percentage savings because of brand trust/loyalty/habit; 2) lacking smartphones and reliable internet infrastructure, the cash-in, cash-out aspect is still the main friction facing most remittance corridors in developing countries, bitcoin does not solve that; 3) it boils down to an execution race and it will be hard to compete against incumbents let alone well-funded MTO startups (like TransferWise).
That’s not to say these rebittance products are not good and will not find success in niches.
For instance, I also spoke with Marwan Forzley (below), CEO of Align Commerce last week. Based on our conversation, in terms of volume his B2B product appears to have more traction than BitPay and it’s less than a year old. What is one of the reasons why? Because the cryptocurrency aspect is fully abstracted away from customers.
Raja Ramachandran (R3CEV), Dan O’Prey (Hyperledger), Daniel Feichtinger (Hyperledger), Marwan Forzley (Align Commerce)
In addition, both BitX and Coins.ph — based on my conversations in Singapore two weeks ago with their teams — seem to be gaining traction in a couple corridors in part because they are focusing on solving actual problems (automating the cash-in/cash-out process) and abstracting away the tech so that the average user is oblivious of what is going on behind the scenes.
Markus Gnirck (StartupBootCamp), Antony Lewis (itBit) and Ron Hose (Coins.ph) at the DBS Hackathon event
On page 162 and 163 the authors write about the Bay Area including 20Mission and Digital Tangible. There is a joke in this space that every year in cryptoland is accelerated like dog years. While 20Mission, the communal housing venue, still exists, the co-working space shut down late last year. Similarly, Digital Tangible has rebranded as Serica and broadened from just precious metals and into securities. In addition, Dan Held (page 164) left Blockchain.info and is now at ChangeTip.
On page 164 they write, “But people attending would go on to become big names in the bitcoin world: Among them were Brian Armstrong and Fred Ehrsam, the founders of Coinbase, which is second only to Blockchain as a leader in digital-wallet services and one of the biggest processors of bitcoin payments for businesses.”
10 pages before this they said how useless digital wallet metrics are. It would have been nice to press both Armstrong and Ehrsam to find out what their actual KYC’ed active users to see if the numbers are any different than the dated presentation.
On page 165 they write:
“It’s a very specific type of brain that’s obsessed with bitcoin,” says Adam Draper, the fourth-generation venture capitalist…”
I hear this often but what does that mean? Is investing genetic? If so, surely there are more studies on it?
For instance, later on page 176 they write, “The youngest Draper, who tells visitors to his personal web site that his life’s ambition is to assist int he creation of an iron-man suit, has clearly inherited his family’s entrepreneurial drive.”
Perhaps Adam Draper is indeed both a bonafide investor and entrepreneur, but it does not seem to be the case that either can be or is necessarily inheritable.
On page 167, “The only option was to “turn into a fractional-reserve bank,” he said jokingly, referring tot he bank model that allows banks to lend out deposits while holding a fraction of those funds in reserve. “They call it a Ponzi scheme unless you have a banking license.”
Why is this statement not challenged? I am not defending rehypothecation or the current banking model, but fractional reserve banking as it is employed in the US is not a Ponzi scheme.
Also on page 167 they write, “First, he had trouble with his payments processor, Dwolla which he later sued for $2 million over what Tradehill claimed were undue chargebacks.”
A snarky thing would be to say he should have used bitcoin, no chargebacks. But the issue here, one that the authors should have pressed is that Tradehill, like Coinbase and Xapo, are effectively behaving like banks. It’s unclear why this irony is not discussed once in the book.
For instance, several pages later on page 170 they once again talk about wallets:
The word wallet is thrown around a lot in bitcoin circles, and it’s an evocative description, but it’s just a user application that allows you to send and receive bitcoins over the bitcoin network. You can download software to create your own wallet — if you really want to be your own bank — but most people go through a wallet provider such as Coinbase or Blockchain, which melded them into user-friendly Web sites and smart phone apps.
I am not sure if it is intentional but the authors clearly understand that holding a private key is the equivalent of being a bank. But rather than say Coinbase is a bank (because they too control private keys), they call them a wallet provider. I have no inside track into how regulators view this but the euphemism of “wallet provider” is thin gruel. On the other hand Blockchain.info does not hold custody of keys but instead provide a user interface — at no point do they touch a privkey (though that does not mean they could not via a man-in-the-middle-attack or scripting errors like the one last December).
On page 171 they talk about Nathan Lands:
The thirty-year-old high school dropout is the cofounder of QuickCoin, the maker of a wallet that’s aimed directly at finding the fastest easiest route to mass adoption. The idea, which he dreamed up with fellow bitcoiner Marshall Hayner one night over a dinner at Ramen Underground, is to give nontechnical bitcoin newcomers access to an easy-to-use mobile wallet viat familiar tools of social media.
Unfortunately this is not how it happened. More in a moment.
Continuing the authors write, “His successes allowed Lands to raise $10 million for one company, Gamestreamer.”
Actually it was Gamify he raised money for (part of the confusion may be due to how it is phrased on his LinkedIn profile).
Next the authors state: “He started buying coins online, where her ran into his eventual business partner, Hayner (with whom he later had a falling-out, and whose stake he bought).”
One of the biggest problems I had with this book is that the authors take claims at face value. To be fair, I probably did a bit too much myself with GCON.
On this point, I checked with Marshall Hayner who noted that this narrative was untrue: “Nathan never bought my stake, nor was I notified of any such exchange.”
While the co-founder dispute deserves its own article or two, the rough timeline is that in late 2013 Hayner created QuickCoin and then several months later on brought Lands on to be the CEO. After a soft launch in May 2014 (which my wife and I attended, see below) Lands maneuvered and got the other employees to first reduce the equity that Hayner had and then fired him so they could open up the cap table to other investors.
QuickCoin launch party with Marshall Hayner, Jackson Palmer (Dogecoin), and my wife
With Hayner out, QuickCoin quickly faded due to the fact that the team had no ties to the local cryptocurrency community. Hayner went on to join Stellar and is now the co-founder of Trees. QuickCoin folded by the end of the year and Lands started Blockai.
On page 174 they discuss VCs involved in funding Bitcoin-related startups:
Jerry Yang, who created the first successful search engine, Yahoo, put money from his AME Ventures into a $30 million funding round for processor BitPay and into one of two $20 million rounds raised by depository and wallet provider Xapo, which offers insurance to depositors and call itself a “bitcoin vault.”
While they likely couldn’t have put it in this section, I think it would have been good for the authors to discuss the debate surrounding what hosted wallets actually are because regulators and courts may not agree with the marketing-speak of these startups.6
On page 177 they write about Boost VC which is run by Adam Draper, “He’d moved first and emerged as the leader in the filed, which meant his start-ups could draw in money from the bigger guys when it came time for larger funding rounds.”
It would be interesting to see the clusters of what VCs do and do not co-invest with others. Perhaps in a few years we can look back and see that indeed, Boost VC did lead the pack. However while there are numerous incubated startups that went on to close seed rounds (Blockcypher, Align Commerce, Hedgy, Bitpagos) as of this writing there is only one incubated company in Boost that has closed a Series A round and that is Mirror (Coinbase, which did receive funding from Adam Draper, was not in Boost). Maybe this is not a good measure for success, perhaps this will change in the future and maybe more have done so privately.
With every facet of our economy now dependent on the kinds of software developed and funded in the Bay Area, and with the Valley’s well-heeled communities becoming a vital fishing ground for political donations and patronage, we’re witnessing a migration of the political and economic power base away from Wall Street to this region.
I have heard variations of this for the past couple of years. Most recently I heard a VC claim that Andreessen Horrowitz (a16z) was the White House of the West Coast and that bankers in New York do not understand this tech. Perhaps it is and perhaps bankers do not understand what a blockchain is.
Either way we should be able to see the consequences to this empirically at some point. Where is the evidence presented by the authors?
Fast forwarding several chapters, on page 287 they write, “Visa, MasterCard, and Western Union combined – to name just three players whose businesses could be significantly reformed — had twenty-seven thousand employees in 2013.”
Perhaps these figures will dramatically change soon, however, the above image are the market caps over the past 5 years of four incumbents: JP Morgan (the largest bank in the US), MasterCard and Visa (the largest card payment providers) and Western Union, the world’s largest money transfer operator.
Will their labor force dramatically change because of cryptocurrencies? That is an open question. Although it is unclear why the labor force at these companies would necessarily shrink because of the existence of Bitcoin rather than expand in the event that these companies integrated parts of the tech (e.g., a distributed ledger) thereby reducing costs and increasing new types of services.
On page 185 they write, “Those unimaginable possibilities exist with bitcoin, Dixon says, because “extensible software platforms that allow anyone to build on top of them are incredibly powerful and have all these unexpected uses. The stuff about fixing the existing payment system is interesting, but what’s superexciting is that you have this new platform on which you can move money and property and potentially build new areas of businesses.”
Maybe this is true. It is unclear from these statements as to what Chris Dixon views as broken about the current payment system. Perhaps it is “broken” in that not everyone on the planet has access to secure, near-instant methods of global value transer. However it is worth noting that cryptocurrencies are not the only competitors in the payments space.
This chapter discussed “The Unbanked” and how Bitcoin supposedly can be a solution to banking these individuals.
On page 188 they discuss a startup called 37coins:
“It uses people in the region lucky enough to afford Android smartphones as “gateways” to transmit the messages. In return, these gateways receive a small fee, which provides the corollary benefit of giving locals the opportunity to create a little business for themselves moving traffic.”
This is a pretty neat idea, both HelloBit and Abra are doing something a little similar. The question however is, why bitcoin? Why do users need to go out of fiat, into bitcoin and back out to fiat? If the end goal is to provide users in developing countries a method to transmit value, why is this extra friction part of the game plan?
Last month I heard of another supposed cryptocurrency “killer app”: smart metering prepaid via bitcoin and how it is supposed to be amazing for the unbanked. The unbanked, they are going to pay for smart metering with money they don’t have for cars they don’t own. There seems to be a disconnect when it comes to financial inclusion as it is sometimes superficially treated in the cryptocurrency world. Many Bitleaders and enthusiasts seem to want to pat themselves on the back for a job that has not been accomplished. How can the cryptocurrency community bring the potential back down to real world situations without overinflating, overhyping or over promising?
If Mercedes or Yamaha held a press conference to talk about the “under-cared” or “under-motorcycled” they would likely face a backlash on social media. Bitcoin the bearer instrument, is treated like a luxury good and expecting under-electrified, under-plumbed, under-interneted people living in subsistence to buy and use it today without the ability to secure the privkey without a trusted third party, seems far fetched (“the under bitcoined!”). Is there a blue print to help all individuals globally move up Maslow’s Hierarchy of Financial Wants & Needs?
On page 189 they write:
“But in the developing world, where the costs of an ineffectual financial system and the burdens of transferring funds are all too clear, cryptocurrencies have a much more compelling pitch to make.”
The problem is actually at the institutional level, institutions which do not disappear because of the Bitcoin blockchain. Nor does Bitcoin solve the identity issue: users still need real-world identity for credit ratings so they can take out loans and obtain investment to build companies.
For instance on page 190 the authors mention the costs of transferring funds to and from Argentina, the Philippines, India and Pakistan. One of the reasons for the high costs is due to institutional problems which is not solved by Bitcoin.
In fact, the authors write, “Banks won’t service these people for various reasons. It’s partly because the poor don’t offer as fat profits as the rich, and it’s partly because they live in places where there isn’t the infrastructure and security needed for banks to build physical branches. But mostly it’s because of weak legal institutions and underdeveloped titling laws.”
This is true, but Bitcoin does not solve this. If local courts or governments do not recognize the land titles that are hashed on the blockchain it does the local residents no good to use Proof of Existence or BlockSign.
They do not clarify this problem through the rest of the chapter. In fact the opposite takes place, as they double down on the reddit narrative:
“Bitcoin, as we know, doesn’t care who you are. It doesn’t care how much money you are willing to save, send, or spend. You, your identity and your credit history are irrelevant. […] If you are living on $50 a week, the $5 you will save will matter a great deal.”
This helps nobody. The people labeled as “unbanked” want to have access to capital markets and need a credit history so they can borrow money to create a companies and build homes. Bitcoin as it currently exists, does not solve those problems.
Furthermore, how do these people get bitcoins in the first place? That challenge is not discussed in the chapter. Nor is the volatility issue, one swift movement that can wipe out the savings of someone living in subsistence, broached. Again, what part of the network does lending on-chain?
On page 192 they write, “They lack access to banks not because they are uneducated, but because of the persistent structural and systemic obstacles confronting people of limited means there: undeveloped systems of documentation and property titling, excessive bureaucracy, cultural snobbery, and corruption. The banking system makes demands that poor people simply can’t meet.”
This is very true. The Singapore conference I attended two weeks ago is just one of many conferences held throughout this year that talked about financial inclusion. Yet Bitcoin does not solve any of these problems. You do not need a proof-of-work blockchain to solve these issues. Perhaps new database or permissioned ledgers can help, but these are social engineering challenges — wet code — that technology qua technology does not necessarily resolve.
Also on page 192 they write, “People who have suffered waves of financial crises are used to volatility. People who have spent years trusting expensive middlemen and flipping back and forth between dollars and their home currency are probably more likely to understand bitcoin’s advantages and weather its flaws.”
This is probably wishful thinking too. Residents of Argentina and Ukraine may be used to volatility but it does not mean it is something they want to adopt. Why would they want to trade one volatile asset for another? Perhaps they will but the authors do not provide any data for actual usage or adoption in these countries, or explain why the residents prefer bitcoin instead of something more global and stable such as the US dollar.
On page 193 they write that, “In many cases, these countries virtually skip over legacy technology, going straight to high-tech fiber-optic cables.”
While there is indeed a number of legacy systems used on any given day in the US, it is not like Bitcoin itself is shiny new tech. While the libraries and BIPS may be new, the components within the consensus critical tech almost all dates back to the 20th century.
For instance, according to Gwern Branwen, the key moving parts that Bitcoin uses:
That’s not to say that Bitcoin is bad, old or that other systems are not old or bad but rather the term “legacy” is pretty relative and undefined in that passage.
On page 194 they discuss China and bitcoin, “With bitcoin, the theory goes, people could bypass that unjust banking system and get their money out of China at low cost.”
This is bad legal advice, just look at the problems this caused Coinbase with regulators a couple months ago. And while you could probably do it low-scale, it then competes with laundering via art sales and Macau junkets and thus expecting this to be the killer use-case for adoption in China is fairly naive.
On page 195 they write “Bitcoin in China is purely a speculator’s game, a way to gamble on its price, either through one of a number of mainland exchanges or by mining it. It is popular — Chinese trading volumes outstrip those seen anywhere else in the world.”
Two months ago Goldman Sachs published a widely circulated report which stated that “80% of bitcoin volume is now exchanged into and out of Chinese yuan.”
This is untrue though as it is solely based on self-reporting metrics from all of the exchanges (via Bitcoinity). As mentioned in chapter 1 notes above, the top 3 exchanges in China run market-making bots which dramatically inflate trading volume by 50-70% each day. While they likely still process a number of legitimate trades, it cannot be said that 80% of bitcoin volume is traded into and out of RMB. The authors of both the report and the book should have investigated this in more depth.
On page 196 they write, “This service, as well as e-marketplace Alibaba’s competing Alipay offering, is helping turn China into the world’s most dynamic e-commerce economy. How is bitcoin to compete with that?”
Next on page 196 they write, “But what about the potential to get around the controls the government puts on cross-border fund transfers?”
By-passing capital controls was discussed two pages before and will likely cause problems for any VC or PE-backed firm in China, the US and other jurisdictions. I am not defending the current policies just being practical: if you are reading their book and plan to do this type of business, be sure to talk to a legal professional first.
On page 197 they discuss a scenario for bitcoin adoption in China: bank crisis. The problem with this is that in the history of banking crisis’ thus far, savers typically flock to other assets, such as US dollars or euros. The authors do not explain why this would change. Now obviously it could or in the words of the authors, the Chinese “may warm to bitcoin.” But this is just idle speculation — where are the surveys or research that clarify this position? Why is it that many killer use-cases for bitcoin typically assumes an economy or two crashes first?
On page 198 they write, “The West Indies even band together to form one international cricket team when they play England, Australia, and other members of the Commonwealth. What they don’t have, however, is a common currency that could improve interisland commerce.”
More idle speculation. Bitcoin will probably not be used as a common currency because policy makers typically want to have discretion via elastic money supplies. In addition, one of the problems that a “common currency” could have is what has plagued the eurozone: differing financial conditions in each country motivate policy makers in each country to lobby for specific monetary agendas (e.g., tightening, loosening). Bitcoin in its current form, cannot be rebased to reflect the changes that policy makers could like to make. While many Bitcoin enthusiasts like this, unless the authors of the book have evidence to the contrary, it is unlikely that the policy makers in the West Indies find this desirable.
On page 199 they write, “A Caribbean dollar remains a pipe dream.”
It is unclear why having a unified global or regional currency is a goal for the authors? Furthermore, there is continued regional integration to remove some frictions, for instance, the ECACH (Eastern Caribbean Automated Clearing House) has been launched and is now live in all 8 member countries.
On page 203 they spoke to Patrick Byrne from Overstock.com about ways Bitcoin supposedly saves merchants money. They note that, “A few weeks later, Byrne announced he would not only be paying bitcoin-accepting vendors one week early, but that he’d also pay his employee bonuses in bitcoin.”
Except so far this whole effort has been a flop for Overstock.com. According to Overstock, in 2014 approximately 11,100 customers paid with bitcoin at both its US and international websites. Altogether this represented roughly $3 million in sales which when coupled with low margin products (based on the top 10 list of things sold on Overstock) is an initiative that Stone Street Advisors labeled “distracting” (see slides 21, 32, 33, 37, 58).
This continues onto page 204, “As a group of businesses in one region begins adopting the currency, it will become more appealing to others with whom they do business. Once such a network of intertwined businesses builds up, no one wants to be excluded from it. Or so the theory goes.” Byrne then goes on to describe network effects and fax machines, suggesting that this is what will happen with bitcoin.
In other words, a circular flow of income. The challenge however goes back to the fact that the time preferences of individuals is different and has not lended towards the theory of spending. As a whole, very few people spend and suppliers typically cash out to reduce their exposure to volatility. Perhaps this will change, but there is no evidence that it has so far.
On page 206 they talk to Rulli from Film Annex (who was introduced in the introduction):
With bitcoin, “you can clearly break down the value of every single stroke on the keyboard, he says.
And you cannot with fiat?
Continuing the authors talk about Rulli:
He wanted the exchange to be solely in bitcoin for other digital currencies, with no option to buy rupees or dollars: “The belief I have is that if you lock these people into this new economy, they will make that new economy as efficient as possible.”
What about volatility? Why are marginalized people being expected to hold onto an asset that fluctuates in value by more than 10% each month? Rulli has a desire to turn the Film Annex Web site “into its own self enclosed bitcoin economy.” There is a term for this: autarky or closed economy.
Continuing Rulli states, ‘If you start giving people opportunities to get out of the economy, they will just cut it down, whereas if the only way for you to enrich yourself is by trading bitcoins for litecoins and dogecoins, you are going to become an expert in that… you will become the best trader in Pakistan.”
This seems to be a questionable strategy: are these users on bitLanders supposed to be artisans or day traders? Why are marginalized people expected to compete with world-class professional traders?
On page 210 the second time the term “virtual currency” is mentioned, this time by the Argentinian central bank.
On page 213 they write, “With bitcoin, it is possible to sen money via a mobile phone, directly between two parties, to bypass that entire cumbersome, expensive system for international transfers.”
What an updated version to the book should include is an actual study for the roundtrip costs of doing international payments and remittances. This is not to defend the incumbents, but rebittance companies and enthusiasts on reddit grossly overstate the savings in many corridors.7 And it still does not do away with the required cash-in / cash-out steps that people in these countries still want and need.
On page 216 they write about the research of Hernando de Soto who discusses the impediments of economic development including the need to document ownership of property. Unfortunately Bitcoin does not currently solve this because ultimately the recognition of a hash of a document on a blockchain comes down to recognition from the same institutions that some of these developing countries lack.
Continuing on page 217 they write that, “Well, the blockchain, if taken to the extent that a new wave of bitcoin innovators believe possible, could replace many of those institutions with a decentralized authority for proving people’s legal obligations and status. In doing so, it could dramatically widen the net of inclusion.”
How? How is this done? Without recognized title transfers, hashing documents onto a chain does not help these people. This is an institutional issue, not one of technology. Human corruption does not disappear because of the existence of Bitcoin.
On page 219 they write, “Like everything else in the cryptocurrency world, the goal is to decentralize, to take power out of the hands of the middleman.”
By recreating the same middleman, depository institutions, yet without robust financial controls.
On page 220 and 221 they mention “basic encryption process” and “standard encryption models” — I believe that it is more accurately stated as cryptographic processes and cryptographic models.
On page 222 they define “Bitcoin 2.0” / “Blockchain 2.0” and put SatoshiDice into that bucket. Ignoring the labels for a moment, I don’t think SatoshiDice or any of the other on-chain casino games are “2.0” — they use the network without coloring any asset.
One quibble with Mike Hearn’s explanation on page 223 is when he says, “But bitcoin has no intermediaries.” This is only true if you control and secure the privkey by yourself. In practice, many “users” do not.
On page 225 they write, “Yet they are run by Wall Street banks and are written and litigated by high-powered lawyers pulling down six- or seven-figure retainers.”
Is it a crime to be able to charge what the market bears for a service? Perhaps some of this technology will eventually reduce the need for certain legal services, but it is unclear what the pay rate of attorneys in NYC has in relation with Bitcoin.
Also on page 225 a small typo: “International Derivatives and Swaps Association (ISDA)” — need to flip Derivatives and Swaps.
On page 226, 227, 229 and 244: nextcoin should be called NXT.
On page 227 they write, “Theses are tradable for bitcoins and other cryptocurrencies on special altcoin exchanges such as Cryptsy, where their value is expected to rise and fall according to the success or failure of the protocol to which they belong.”
There is a disconnect between the utility of a chain and the speculative activity around the token. For instance, most day traders likely do not care about the actual decentralization of a network, for if they did, it would be reflected in prices of each chain. There are technically more miners (block makers) on dozens of alternative proof-of-work chains than there in either bitcoin or litecoin yet market prices are (currently) not higher for more decentralized chains.
On page 228 they write that:
“Under their model, the underlying bitcoin transactions are usually of small value — as low as a “Satoshi” (BTC0.00000001). That’s because the bitcoin value is essentially irrelevant versus the more important purpose of conveying the decentralized application’s critical metadata across the network, even though some value exchange is needed to make the communication of information happen.”
Actually in practice the limit for watermarked coins typically resides around 0.0001 BTC. If it goes beneath 546 satoshi, then it is considered dust and not included into a block. Watermarked coins also make the network top heavy and probably insecure.8
On page 209, the third time “virtual currency” is used and comes from Daniel Larimer, but without quotes.
On page 230 they discuss an idea from Daniel Larimer to do blockchain-based voting. While it sounds neat in theory, in practice it still would require identity which again, Bitcoin doesn’t solve. Also, it is unclear from the example in the book as to why it is any more effective/superior than an E2E system such as Helios.
On page 238 they write, “It gets back to the seigniorage problem we discussed in chapter 5 and which Nakamoto chose to tackle through the competition for bitcoins.”
I am not sure I would classify it as a problem per se, it is by design one method for rewarding security and distributing tokens. There may be other ways to do it in a decentralized manner but that is beyond the scope of this review.
On page 239 they discuss MaidSafe and describe the “ecological disaster” that awaits data-center-based storage. This seems a bit alarmist because just in terms of physics, centralized warehouses of storage space and compute will be more efficient than a decentralized topology (and faster too). This is discussed in Chapter 3 (under “Another facsimile”).
Continuing they quote the following statement from David Irvine, founder of MaidSafe: “Data centers, he says, are an enormous waste of electricity because they store vast amounts of underutilized computing power in huge warehouse that need air-condition and expensive maintenance.”
Or in other words: #bitcoin
On page 242 they mention Realcoin whose name has since been changed to Tether. It is worth pointing out that Tether does not reduce counterparty risk, users are still reliant on the exchange (in this case Bitfinex) from not being hacked or shut down via social engineering.
On page 244, again to illustrate how fast this space moves, Swarm has now pivoted from offering cryptocurrency-denominated investment vehicles into voting applications and Open-Transactions has hit a bit of a rough patch, its CTO, Chris Odom stepped down in March and the project has not had any public announcements since then.
If you missed it, the last few weeks on social media have involved a large debate around blockchain stability with respect to increasing block sizes. During one specific exchange, several developers debated as to “who was in charge,” with Mike Hearn insisting that Satoshi left Gavin in charge and Greg Maxwell stating that this is incorrect.
This ties in with the beginning of page 247, the authors write about Gavin Andresen, “A week earlier he had cleared out his office at the home he shares with his wife, Michele – a geology professor at the University of Massachusetts — and two kids. He’d decided that a man essentially if not titularly in charge of running an $8 billion economy needed something more than a home office.”
Who is in charge of Bitcoin? Enthusiasts on reddit and at conferences claim no one is. The Bitcoin Foundation claims five people are (those with commit access). Occasionally mainstream media sites claim the Bitcoin CEO or CFO is fired/jailed/dead/bankrupt.
The truth of the matter is that it is the miners who decide what code to update and use and for some reason they are pretty quiet during all of this hub bub. Beyond that, there is a public goods problem and as shown in the image above, it devolves into various parties lobbying for one particular view over another.
The authors wrote about this on page 247, “The foundation pays him to coordinate the input of the hundreds of far-flung techies who tinker away at the open-licensed software. Right now, the bitcoin community needed answers and in the absence of a CEO, a CTO, or any central authority to turn to, Andresen was their best hope.”
It is unclear how this will evolve but is a ripe topic of study. Perhaps the second edition will include other thoughts on how this role has changed over time.
On page 251 they write, “Probably ten thousand of the best developers in the world are working on this project,” says Chris Dixon, a partner at venture capital firm Andreessen Horowitz.
How does he know this? There are not 10,000 users making changes to Bitcoin core libraries on github or 10,000 subscribers to the bitcoin development mailing list or IRC rooms. I doubt that if you added up all of the employees of every venture-backed company in the overall Bitcoin world, that the amount would equate to 2,000 let alone 10,000 developers. Perhaps it will by the end of this year but this number seems to be a bit of an exaggeration.
Continuing Dixon states, “You read these criticisms that ‘bitcoin has this flaw and bitcoin has that flaw,’ and we’re like ‘Well, great. Bitcoin has ten thousand people working hard on that.”
This is not true. There is a public goods problem and coordination problem. Each developer and clique of developers has their own priorities and potential agenda for what to build and deploy. It cannot be said that they’re all working towards one specific area. How many are working on the Lightning Network? Or on transaction malleability (which is still not “fixed”)? How many are working on these CVE?
On page 254 they discuss Paul Baran’s paper “On Distributed Communications Networks,” the image of which has been used over the years and I actually used for my paper last month.
On page 255 the fourth usage of “virtual currency” appears regarding once more, FinCEN director Jennifer Shasky. Followed by page 256 with another use of “virtual currency.” On page 257 Benjamin Lawsky was quoted using “virtual currency.” Page 259 the term “virtual currency” appears when the European Banking Authority is quoted. Page 260 and 261 sees “virtual currency” being used in relation with NYDFS and Lawsky once more. On page 264 another use of “virtual currency” is used and this time in relation with Canadian regulations from June 2014.
On page 265 they mention “After the People’s Bank of China’s antibitcoin directives…”
I am not sure the directives were necessarily anti-bitcoin per se. Rather they prohibited financial institutions like banks and payment processors from directly handling cryptocurrencies such as bitcoins. The regulatory framework is still quite nebulous but again, going back to “excessive” in the introduction above, it is unclear why this is deemed “anti-bitcoin” when mining and trading activity is still allowed to take place. Inconsistent and unhelpful, yes. Anti? Maybe, maybe not.
Also on page 265 they mention Temasek Holdings, a sovereign wealth fund in Singapore that allegedly has bitcoins in its portfolio. When I was visiting there, I spoke with a managing director from Temasek two weeks ago and he said they are not invested in any Bitcoin companies and the lunchroom experiment with bitcoins has ended.
On page 268 the authors discuss “wallets” once more this time in relation with Mt.Gox: “All the bitcoins were controlled by the exchange in its own wallets” and “Reuters reported that only Karpeles knew the passwords to the Mt. Gox wallets and that he refused a 2012 request from employees to expand access in the event that he became incapacitated.”
On page 275 the authors use a good nonce, “übercentralization.”
On page 277 they write, “While no self-respecting bitcoiner would ever describe Google or Facebook as decentralized institutions, not with their corporate-controlled servers and vast databases of customers’ personal information, these giant Internet firms of our day got there by encouraging peer-to-peer and middleman-free activities.”
In the notes on the margin I wrote “huh?” And I am still confused because each of these companies attempts to build a moat around their property. Google has tried 47 different ways to create a social network even going so far as to cutting off its nose (Google Reader, RIP) to spite its face all with the goal of keeping traffic, clicks and eyeballs on platforms it owns. And this is understandable. Similarly Coinbase and other “universal hosted wallets” are also trying to build a walled garden of apps with the aim of stickiness — finding something that will keep users on their platform.
On page 277 they also wrote that, “Perhaps these trends can continue to coexist if the decentralizing movements remains limited to areas of the economy that don’t bleed into the larger sectors that Big Business dominates.”
What about Big Bitcoin? The joke is that there are 300,027 advocacy groups in Bitcoinland: 300,000 privkey holders who invested in bitcoin and 27 actual organizations that actively promote Bitcoin. There is probably only one quasi self-regulating organization (SRO), DATA. And the advocacy groups are well funded by VC-backed companies and investors, just look at CoinCenter’s rolodex.
On page 280 they write, “Embracing a cryptoccurency-like view of finance, it has started an investment program that allows people invest directly in the company, buying notes backed by specific hard assets, such as individual stores, trucks, even mattress pads. No investment bank is involved, no intermediary. Investors are simply lending U-Haul money, peer-to-peer, and in return getting a promissory note with fixed interested payments, underwritten by the company’s assets.”
This sounds a lot like a security as defined by the Howey test. Again, before participating in such an activity be sure to talk with a legal professional.9
On page 281 they use the term “virtual currencies” for the 11th time, this time in reference to MasterCard’s lobbying efforts in DC for Congress.
On page 283 a small typo, “But here’s the rub: because they are tapped” — (should be trapped).
On page 283 they write, “By comparison, bitcoin processors such as BitPay, Coinbase, and GoCoin say they’ve been profitable more or less from day one, given their low overheads and the comparatively tiny fees charged by miners on the blockchain.”
This is probably false. I would challenge this view, and that none of them are currently breaking even on merchant processing fees alone.
In fact, they likely have the same user acquisition costs and compliance costs as all payment processors do.
For instance, in October 2014, Brian Armstrong and Fred Ehrsam, co-founders of Coinbase, did a reddit AMA. At the 21:12 minute mark (video):
Q: Is Coinbase profitable or not, if not, when?
A: It’s happened to be profitable at times, at the moment it’s not; we’re not burning too much cash. I think that the basic idea here is to grow and by us growing we help the entire ecosystem grow — without dying. So not at the moment but not far.
It’s pretty clear from BitPay’s numbers that unless they’ve been operating a high volume exchange, they are likely unprofitable.
Why? Because, in part of the high burn rate. What does this mean?
Last week Moe Levin, former Director of European Business Development at BitPay, was interviewed by deBitcoin, below is one detailed exchange starting at 1:57m:
Q: There was a lot of stories in the press about BitPay laying off people, can you comment on that?
A: Yea, what happened was we had a high burn rate and the company necessarily needed to scale back a little bit on how many people we hired, how many people we had on board, how much we sponsored things. I mean things were getting a little bit out of hand with sponsorships, football games and expansion — more care needed to be put on how and where we spent the money.
Q: Can you elaborate on the burn rate? Tim Swanson wrote a piece on BitPay in April, published this piece about the economy, the BitPay economy. Posted this piece on the burn rate and actual figures, have you read that piece? Can you comment on that?
A: Yes, it is especially hard for a company to build traction when they start off. Any start up is difficult to build traction. It’s doubly hard, the hardness is amplified when a company enters a market with competitors that have near unlimited resources because the other companies can either blow you out of the water or have better marketing strategies or they can do a ton of different things to make your startup more irrelevant. Standard in any company but it is doubly difficult when you enter a market like that. In the payments industry, forget about Bitcoin for a second, in the payments industry and the mobile commerce, ecommerce, company-to-company payments industry there are massive players with investments and venture backed companies in the billions. Competing at that stage is tricky and it necessarily requires a burn rate that is much higher than the average startup because of how you need to compete in this space. What is also important is that the regulation costs a lot of money for the startups in the Bitcoin economy. It’s the perfect storm of how a startup will be hit with a ton of expenses early on and that can hurt the growth of a company. Even though a lot of the money that went into it was growth capital it takes a while to get the balance right between spending and growing.
On page 284 they write, “That leads us to one important question: What happens to banks as credit providers if that age arrives? Any threat to this role could be a negotiating chip for banks in their marketing battle with the new technology.”
This is a good question and it dovetails with the “Fedcoin” discussion over the past 6 months.10
On page 285 they write, “With paper money they can purchase arms, launch wars, raise debt to finance those conflicts, and then demand tax payments in that same currency to repay those debts.”
This is a common misconception, one involving lots of passionate Youtube videos, that before central banks were established or fiat currencies were issued, that there was no war or “less war.” On page 309 they quote Roger Ver at a Bitcoin conference saying, “they’ll no longer be able to fund these giant war machines that are killing people around the world. So I see bitcoin as a lever that I can use to move the world in a more peaceful direction.”
Cryptocurrencies such as Bitcoin will not end wars for the same reason that precious metals did not prevent wars: the privkey has no control over the “wet code” on the edges. Wars have occurred since time immemorial due to conflicts between humans and will likely continue to occur into the future (I am sure this statement will be misconstrued on reddit to say that I am in support of genocide and war).
On page 286 they write, “Gil Luria, an analyst at Wedbush Securities who has done some of the most in-depth analysis of cryptocurrency’s potential, argues that 21 percent of U.S. GDP is based in “trust” industries, those that perform middlemen tasks that blockchain can digitize and automate.”
In looking at the endnote citation (pdf) it is clear that Luria and his team is incorrect in just about all of the analysis that month as they rely on unfounded assumptions to both adoption and the price of bitcoin. That’s not to say some type of black swan events cannot or will not occur, but probably not for the reasons laid out by the Wedbush team. The metrics and probabilities are entirely arbitrary.
For instance, the Wedbush analysts state, “Our conversation with bitcoin traders (and Wall Street traders trading bitcoin lead us to believe they see opportunity in a market that has frequent disruptive news flow and large movements that reflect that news flow.”
Who are these traders? Are they disinterested and objective parties?
For instance, a year ago (in February 2014), Founders Gridasked 50 Bitcoin “experts” what their bitcoin price predictions were over the next year. The end result — all but a couple were completely, very wrong (see this spreadsheet for a line-by-line itemization). Later, in May 2014, CoinTelegraph asked (video) more than 30 Bitcoin “experts” as to what their bitcoin predictions were for the end of 2014. Once again, all but a couple were completely, very wrong.
Or in short, no one has a very good track record of predicting either prices or adoption. Thus it is unclear from their statements why a cryptocurrency such as Bitcoin will automatically begin performing the tasks that comprise 21% of US economic output based on “trust.”
On page 288 they write, “So expect a backlash once banks start shutting back-office administrative centers in midtown Manhattan or London’s Canary Wharf when their merchant customers start booking more customer sales via cryptocurrency systems to avoid the 3 percent transaction fees.”
I think there is a lot of conflation here. For starters, back-offices could be reformed with the integration of distributed ledgers, but probably not cryptocurrency systems (why would a trusted network need proof-of-work?). Secondly, the empirical data thus far suggests that it doesn’t matter how many merchants adopt cryptocurrencies as payments, what matters is consumer adoption — and thus far the former out paces the latter by several an enormous margin. Third, that 3% is broken down and paid to a variety of other participants not just Visa or MasterCard. Fourth, the US economy (like that of Europe and many other regions) is consumer driven — supply does not necessarily create its own demand.
There is one more point, but first the authors quote Chris Dixon from Andreessen Horowitz, “On the one hand you have the bank person who loses their job, and everyone feels bad about that person, and on the other hand, everyone else saves three percent, which economically can have a huge impact because it means small businesses widen their profit margins.”
There are two reasons for why it could be temporarily cheaper to use Coinbase:
1) VC funding and exchange activity subsidizes the “loss-leader” of payment processing;
2) because Coinbase outsources the actual transaction verification to a third party (miners), they are dependent on fees to miners staying low or non-existent. At some point the fees will have to increase and those fees will then either need to be absorbed by Coinbase or passed on to customers.
On page 290 they quote Larry Summers, “So it seems to me that the people who confidently reject all the innovation here [in blockchain-based payment and monetary systems] are on the wrong side of history.”
Who are these people? Even Jeffrey Robinson finds parts of the overall tech of interest. I see this claim often on social media but it seems like a strawman. Skepticism about extraordinary claims that lack extraordinary proof does not seem unwarranted or unjustified.
On page 292 they write, “But, to borrow an idea from an editor of ours, such utopian projects often end up like Ultimate Frisbee competitions, which by design have no referees — only “observers” who arbitrate calls — and where disputes over rule violations often devolve into shouting matches that are won by whichever player yells the loudest, takes the most uncompromising stance, and persuades the observer.”
This is the exact description of how Bitcoin development works via reddit, Twitter, Bitcoin Talk, the Bitcoin Dev mailing list, IRC and so forth. This is not a rational way to build a financial product. Increasing block sizes that impact a multi-billion dollar asset class should not be determined by how many Likes you get on Facebook or how often you get to sit on panels at conferences.
Final chapter (conclusion):
On page 292 they write, “Nobody’s fully studied how much business merchants are doing with bitcoin and cryptocurrencies, but actual and anecdotal reports tend to peg it at a low number, about 1 percent of total sales for the few that accept them.”
My one quibble is that they as journalists were in a position to ask payment processors for these numbers.
Fortunately we have a transparent, public record that serves as Plan B: reused addresses on the Bitcoin blockchain.
As describedin detail a couple weeks ago, the chart above is a log scale measuring the amount of bitcoins that both BitPay (in green) and Evolution (in red) received starting January 16, 2014. The drop off at the end in March 2015 is related to the exit scam that Evolution underwent (and the drop off for BitPay is related to a limitation in WalletExplorer’s data).
As we can see here, based on the clusters labeled by WalletExplorer, on any given day BitPay processes about 1,200 bitcoins (the actual number is probably about 10% higher).
The chart above are self-reported transaction numbers from Coinbase. While it is unclear what each transaction can or do represent, in aggregate it appears to be relatively flat over the past year.11 Perhaps that will change in the future.
On page 295 they write, “Volatility in bitcoin’s price will also eventually decline as more traders enter the market and exchanges become more sophisticated.”
As Christopher Hitchens once remarked, that which can be asserted without evidence, can be dismissed without evidence. Those making a positive claim (that volatility will decline) are the party that needs to prove this and they do not in this book. Perhaps volatility will somehow disappear, but not for the non-technical reasons they describe.
At the bottom of page 295 they write, “Even so, we will go out on a limb here and argue that encryption-based, decentralized digital currencies do have a future.”
Again, there is no encryption in cryptocurrencies, only cryptographic primitives. Also, as described in the introductory notes above, virtual currencies are not synonymous with digital currencies.
Also on page 295 they write, “Far more important, it solves some big problems that are impossible to address within the underlying payment infrastructure.”
Yes, there are indeed problems with identity and fraud but it is unclear from this book what Bitcoin actually solves. No one double-spends on the Visa network. No one has, publicly, hacked the Visa Network (which has 42 firewalls and a moat). The vulnerabilities and hacks that take place are almost always at the edges, in retailers such as Home Depot and Target (which is unfortunately named). This is not to say that payment rails and access to them cannot be improved or made more accessible, but that case is not made in this book.
On page 296 they write, “Imagine how much wider the use of cyptocurrency would be if a major retailer such as Walmart switched to a blockchain-based payment network in order to cut tens of billions of dollars in transaction costs off the $350 billion it sends annually to tens of thousands of suppliers worldwide.”
Again this is conflating several things. Walmart does not need a proof-of-work blockchain when it sends value to trusted third parties. All the participants are doxxed and KCY’ed. Nor does it need to convert fiat -> into a cryptocurrency -> into fiat to pay retailers. Instead, Walmart in theory, could use some type of distributed ledger system like SKUChain to track the provenance of items, but again, proof-of-work used by Bitcoin are unneeded for this utility because parties are known.
Also, while the authors recognize that bitcoins currently represent a small fraction of payments processed by most retailers, one of the reasons for why they may not have seen a dramatic improvement in their bottom line because people — as shown with the Wence Casares citation above (assuming the 96% figure is accurate) — do not typically purchase bitcoins in order to spend them but rather invest and permanently hold them. Perhaps that may change in the future.
On page 297 they write, “But now bitcoin offers an alternative, one that is significantly more useful than gold.”
That’s an unfounded claim. The two have different sets of utility and different trade-offs We know precious metals have some use-value beyond ornamentation, what are the industrial usages of bitcoin? In terms of security vulnerabilities there are trade-offs of owning either one. While gold can be confiscated and stolen, to some degree the same challenge holds true with cryptocurrencies due to its bearer nature (over a million bitcoins have been lost, stolen, seized and destroyed).12 One advantage that bitcoin seems to have is cheaper transportation costs but that is largely dependent on subsidized transaction fees (through block rewards) and the lack of incentives to attack high-value transactions thus far.
On page 300 they write, “As you’ll know from having read this book, a bitcoin-dominant world would have far more sweeping implications: for one, both banks and governments would have less power.”
That was not proven in this book. In fact, the typical scenarios involved the success of trusted third parties like Coinbase and Xapo, which are banks by any other name. And it is unclear why governments would have less power. Maybe they will but that was not fleshed out.
On page 301 they write, “In that case, cryptocurrency protocols and blockchain-based systems for confirming transactions would replace the cumbersome payment system that’s currently run by banks, credit-card companies, payment processors and foreign-exchange traders.”
The authors use the word cumbersome too liberally. To a consumer and even a merchant, the average swipeable (nonce!) credit card and debit card transaction is abstracted away and invisible. In place of these institutions reviled by the authors are, in practice, the very same entities: banks (Coinbase, Xapo), credit-card companies (Snapcard, Freshpay), payment processors (BitPay, GoCoin) and foreign-exchange traders (a hundred different cryptocurrency exchanges). Perhaps this will change in the future or maybe not.
On page 305 they write about a “Digital dollar.” Stating, “Central banks could, for example, set negative interest rates on bank deposits, since savers would no longer be able to flee into cash and avoid the penalty.”
This is an interesting thought experiment, one raised by Miles Kimball several months ago and one that intersects with what Richard Brown and Robert Sams have discussed in relation to a Fedcoin.
On page 306 they write about currency reserves, “we doubt officials in Paris or Beijing are conceiving of such things right now, but if cryptocurrency technology lives up to its potential, they may have to think about it.”
This is wishful thinking at best. As described in Chapter 13, most proponents of a “Bitcoin reserve currency” are missing some fundamental understanding of what a reserve currency is or how a currency becomes one.
Because there is an enormous amount of confusion in the Bitcoin community as to what reserve currencies are and how they are used, it is recommended that readers peruse what Patrick Chovanec wrote several years ago – perhaps the most concise explanation – as it relates to China (RMB), the United Kingdom (the pound) and the United States (the dollar):
There are four main factors that set the Pound and the Dollar apart as viable and attractive reserve currencies. Each was necessary. They were liquid. They were available. And they were perceived as safe. I’m going to run through each of these conditions in turn. I will consider how they applied to the Pound and the Dollar, and to what extent they are satisfied by China’s Renminbi.
(1) Necessity. The fundamental purpose of a reserve currency is to settle external obligations. The greater quantity and variety of obligations a particular currency can settle, the more useful it is as a reserve currency. The currency of a country that produces little of note and lacks funds to lend or invest is not nearly as useful as one whose home economy produces many goods and services desired around the world, serves as an important source of capital, and has many commercial partners who also find its currency relevant to meeting their own obligations. This idea — that the dominant reserve currency derives its status from its connection with the dominant national economy in an interconnected world – is what underlies Roubini’s reasoning that the Renminbi may be next in line to replace the Dollar.
But this conclusion misses something important. A reserve currency must not only be capable of settling obligations in connection with a heavy-weight economy. It must be required to. Because if you can settle those obligations, as sizeable and important as they may be, using your own currency — or the currency of another leading economy — there is no reason to hold that country’s currency as a reserve. That is precisely the case today with China.
It is unclear how or why some Bitcoin advocates can suggest that bitcoins will ever be used as a reserve currency when there is no demand for the currency to meet external trading obligations let alone in the magnitude that these other currencies do (RMB, USD, GBP).
On page 307 they write:
Under this imagined Bretton Woods II, perhaps the IMF would create its own cryptocurrency, with nodes for managing the blockchain situated in proportionate numbers within all the member countries, where none could ever have veto power, to avoid a state-run 51 percent attack.
Proof-of-work mining on a trusted network is entirely unnecessary yet this type of scenario is propagated by a number of people in the Bitcoin space including Adam Ludwin (CEO of Chain.com) and Antonis Polemitis (investor at Ledra Capital). Two months ago on a panel at the Stanford Blockchain event, Ludwin predicted that in the future governments would subsidize mining. Again, the sole purpose of mining on a proof-of-work blockchain is because the actors cannot trust one another. Yet on a government-run network, there are no unverified actors (Polemitis has proposed a similar proof-of-work solution for Fedcoin).
Again, there is no reason for the Fed, or any bank for that matter, to use a Bitcoin-like system because all parties are known. Proof-of-work is only useful and necessary when actors are unknown and untrusted. The incentive and cost structure for maintaining a proof-of-work network is entirely unnecessary for financial services institutions. Furthermore, maintaining anonymous validators while simultaneously requiring KYC/AML on end users is a bit nonsensical (which is what the Bitcoin community has done actually). Not only do you have the cost structures of both worlds but you have none of the benefits. If validators are known, then they can be held legally responsible for say, double spending or censoring transactions.
Robert Sams recently noted the absurdity of this hydra, why permissionless systems are a poor method for managing off-chain assets:
The financial system and its regulators go to great lengths to ensure that something called settlement finality takes place. There is a point in time in which a trade brings about the transfer of ownership–definitively. At some point settlement instructions are irrevocable and transactions are irreversible. This is a core design principle of the financial system because ambiguity about settlement finality is a systemic risk. Imagine if the line items of financial institution’s balance sheet were only probabilistic. You own … of … with 97.5% probability. That is, effectively, what a proof-of-work based distributed ledger gives you. Except that you don’t know what the probabilities are because the attack vectors are based not on provable results from computers science but economic models. Do you want to build a settlement system on that edifice?
Though as shown by the NASDAQ annoucement, this will likely not stop people from trial by fire.
Bertha Benz, wife of Karl Benz, is perhaps best known for her August 1886 jaunt through present day Baden-Württemberg in which she became the first person to travel “cross-country” in an automobile — a distance of 106 kilometers.
It is unclear what will become of Bitcoin or cryptocurrencies, but if the enthusiasm of the 19th century German countryside echoed similar excitement as reddit sock puppets do about magic internet money, they must have been very disappointed by the long adoption process for horseless carriages to overtake horses as the primary mode of transportation. For instance, despite depictions of a widely motorized Wehrmacht, during World War II the Teutonic Heer army depended largely on horses to move its divisions across the battlefields of Europe: 80% of its entire transportation was equestrian. Or maybe as the popular narrative states: cryptocurrencies are like social networks and one or two will be adopted quickly, by everyone.
So is this book the equivalent to a premature The Age of Automobile? Or The New Age of Trusted Third Parties?
Its strength is in simplicity and concision. Yet it sacrifices some technical accuracy to achieve this. While it may appear that I hated the book or that each page was riddled with errors, it bears mentioning that there were many things they did a good job with in a fast-moving fluid industry. They probably got more right than wrong and if someone is wholly unfamiliar with the topic this book would probably serve as a decent primer.
Furthermore, a number of the incredulous comments that are discussed above relate more towards the people they interviewed than the authors themselves and you cannot really blame them if the interviewees are speaking on topics they are not experts on (such as volatility). It is also worth pointing out that this book appears to have been completed around sometime last August and the space has evolved a bit since then and of which we have the benefit of hindsight to utilize.
You cannot please everyone
For me, I would have preferred more data. VC funding is not necessarily a good metric for productive working capital (see the Cleantech boom and bust). Furthermore, VCs can and often are wrong on their bets (hence the reason not all of them outperform the market).13 Notable venture-backed flops: Fab, Clinkle, DigiCash, Pets.com and Beenz. I think we all miss the heady days of Cracked.com.
Only two charts related to Bitcoin were used: 1) historical prices, 2) historical network hashrate. In terms of balance, they only cited one actual “skeptic” and that was Mark Williams’ testimony — not from him personally. For comparison, it had a different look and feel than Robinson’s “BitCon” (here’s my mini review).
Both Michael and Paul were gracious to sign my book and answer my questions at Google and I think they genuinely mean well with their investigatory endeavor. Furthermore, the decentralized/distributed ledger tent is big enough for a wide-array of views and disagreement. While I am unaware of any future editions, I look forward to reading their articles that tackle some of the challenges I proposed above. Or as is often unironically stated on reddit: you just strengthened (sic) my argument.
Note: I contacted Rulli who mentioned that the project has been ongoing for about 10 years — they have been distributing value since 2005 and adopted bitcoin due to what he calls a “better payment solution.” They have 500,000 registered users and all compete for the same pot of bitcoins each month.

Additional calculations from Dave Hudson:
– Current Bitcoin network capacity: approximately 320 PH/s (320 x 10^15)
– Best case power efficiency (shipping today): approximately 0.5 J/GH (0.5 x 10^-9 J/H)
Likely power efficiency: approximately 1.0 J/GH (1 x 10^-9 J/H) = 2 x best case
– Best case power usage (sustained): 320 x 10^15 x 0.5 x 10^-9 = 160 x 10^6 W = 160 MW
Likely power efficiency: 160 x 2 = 320 MW
– Best case power usage per day: 160 x 24 = 3840 MWh = 3.84 GWh
Likely power usage per day: 320 x 24 = 7680 MWh = 7.68 GWh
– Best case power usage per year: 3.84 x 365 = 1401.6 GWh = 1.4 TWh
Likely power usage per year: 7.68 x 365 = 2803.2 GWh = 2.8 TWh
The best case example would represent the entire Bitcoin network using the best possible hardware and doesn’t account for any cooling or any other computers used in the Bitcoin network. As such it represents an impossible best version of a network of this size. The likely example is probably closer as there is older hardware still in use and most data centers need cooling of some sort.
The US Energy Information Administration estimated the US power generation capacity for 2012 at 1051 GW so the 320 MW number would represent 0.03% of the total electricity supply for the US. Assuming that we take the 320 MW figure then that would put Bitcoin at about 10% of Ireland’s electricity supply. [↩]
Jeffrey Robinson is the author of over 20 books This past week he published a new book that looks at the history and some characters of the Bitcoin ecosystem called “BitCon: The Naked Truth About Bitcoin.” Earlier this summer he contacted me and asked me several questions, the answers of which appear in several spots in the book.
If you are tired of the continuous pumping on reddit, Twitter and conferences you will likely enjoy his challenges to cliche arguments.
For instance he pointed out that all the wars in the 16th, 17th and 18th century were not funded by central banks therefore it is unlikely that in the event Bitcoin did somehow take over the world, it probably would not make war disappear. The term he uses to identify “true believers” that make such argument is Planet-Bitcoin — a place where this vocal group of people reside. Speaking of which, probably the best quip throughout the book was at the end when a “true believer” calls him a “currency denier.” Is that a thing now?
Two errors that stood out that I noticed: the Icelandic government actually ignored auroracoin entirely (it was just some random people that did the “airdrop”). The other part is he stated, “So much so that amateurs have been thrown overboard by mining pools who can afford the ever-increasingly gigantic […]” Technically these are farms not pools.
Two economic terms that are frequently glossed over by many digital currency advocates:
Recreating a circular flow of income when there are already dozens of competing currencies (e.g., USD, euro, yen) that currently fulfill this task will always be an ongoing hurdle for Bitcoin-like digital currencies.
Regarding my last quote in the book, I should point out that Ripple may not necessarily be a “better” protocol, it just solves different needs in different circumstances. Though for some of the purposes for which Bitcoin is being shoe horned for, Ripple may be a better solution of the two. However this is an empirical issue, we cannot know a priori and a TCO analysis should be undertaken by each enterprise. As far as the fate of Bitcoin — that it can survive because its big holders will subsidize it — perhaps this could be the case, but it is also hard to say how long “whales” or big holders will be willing to subsidize any chain. It is also unclear how many coins that purported whales actually control still (versus how much they have cashed out) — I have heard all sorts of ownership numbers and if you add them all up, they total more than 13.2 million coins that have been mined so someone at these conferences is embellishing.
A taste of quotes
While the user adoption, merchant adoption and transactional volume numbers will likely change in the coming weeks and months, it is a quick read and below are some choice quotes that stuck out to me.
On first-movers and fads:
The Dot-Com boom, and subsequent bust, of the 1990s rewrote that script. So did Betamax, mood rings, semi-automatic transmissions, floppy disks, 8-Track, Amphicars, Apple Lisa, WebTV, IBM PCjr, Zune, and the Segway.
On the externalizing the costs of mining:
Some miners even employ methods that are not exactly “cricket.” There was one in Holland who literally stole the electricity he needed to run 21 rigs. He eventually got caught. (source)
Regarding the continually misquoted numbers pulled from Coinometrics, Robinson asks co-founder Jonathan Levin for clarification:
“[…] It was right around the December price increase, so there was lots of stuff going on in the press about bitcoin, and all over social media, as well. Everyone was using social media to promote bitcoin Black Friday. It was a massive promotion and it paid off with big sales. But the numbers I’ve got for that period worked out at around 5%. So when you’re talking about comparing PayPal and Western Union with bitcoin the rest of the time, then only about 3% are for goods and services. That puts you at one-hundredth of any other network.” A good reason why, Levin says, might be because, “Bitcoin is terribly inefficient. It’s all about decentralized trust. But if you don’t need to have decentralized trust, updating a spreadsheet in a bank is far more efficient. The cost of updating the ledger is more expensive with bitcoin and takes much longer than any system in the world.” With bitcoin verifications taking up to 10 minutes, he asks, “What happens with Visa? How quickly do they reconcile their database? Instantaneously. Bitcoin introduces the ability to cut out the middleman. That’s fine. But the paradigm is that while the blockchain technology offers decentralization, it doesn’t give you a more efficient system.” That’s not bitcoin’s only “bragging rights” problem. According to Levin, “There is no correlation with the increase of merchants allowing customers to pay with bitcoin and the amount of bitcoins being used for transactions. It’s linear.”
On his use of imagery:
The New York Post’s Sunday business editor Jonathon Trugman wittily describes bitcoin as, “The Tinkertoy crypto-currency,” likening it to, “A modern-day game of three-card monte, with a little Sudoku thrown in, just to add a touch of mystique.”
If it turns out to be true that $ 400 million has been stolen, it’s more than the sum total of all the bank robberies in the US for the past seven years.
Regarding the hype of adoption and ATMs in Canada:
However, the Canadian Payments Association reported in April 2014 that while Canada is estimated to account for as much as 4% of bitcoin’s global transactions – ranking it number two in the world, behind the United States but ahead of China – the volume of bitcoin transactions represents a mere 0.01% of Canada’s total debit and credit-based transactions.
“[…] not just that his is the largest company to do that, but a fast check of Google reveals there are actually more piano tuners just in Canada than there are businesses anywhere in the world of any size, keeping bitcoins on their books.
Dr Yanis Varoufakis, a political economist at the University of Texas and the University of Athens, says speculative demand for bitcoin outstrips transactional demand, “By a long mile. Bitcoin transactions don’t go beyond the first transaction. The people who have accepted bitcoins don’t use them to buy something else. It gets back to the circular flow of income. When Starbucks not only accepts bitcoins but pays their workers in bitcoins and pays their suppliers in bitcoins, when you go back four of five stages of productions using bitcoin, then bitcoin will have made it. But that isn’t happening now and I don’t think that will happen.” Because it isn’t happening now, he continues, and because so many more people are speculating on bitcoin rather than transacting with it, “Volatility will remain huge and will deter those who might have wanted to enter the bitcoin economy as users, as opposed to speculators. Thus, just as bad money drives out good money, Gresham’s famous law, speculative demand for bitcoins drives out transactional demand for it.”
On the odds that Bitcoin will supplant the state:
Professor Stephen Mihm, who teaches economic, cultural and intellectual history of 18th and 19th century America at the University of Georgia, is convinced that bitcoin will not survive, because it cannot survive. He’s written, “Anyone who thinks that bitcoin will triumph, has to believe that it will succeed where earlier generations of private currencies failed, that bitcoin will, improbably, manage to overthrow more than centuries’ worth of accumulated state power, jealously guarded and ruthlessly enforced. That’s a preposterous fantasy, and a dangerous one if you’re an investor. Indeed, people who believe that governments of the world will let a stateless crypto-currency usurp their hard-won monetary prerogatives aren’t forecasting the future. They’re living in the past.”
More on whether or not it will supplant the state:
He says, another reason why bitcoin won’t be the one is because, “The misguided notion that you can free government from currency. Governments regulate money. They put certain constraints on it that you have to follow. So the technology that evolves must be ready to accommodate that. Most commerce will still be done in dollars. Currency is backed by the full faith and credit of a government. Bitcoin is backed by the full faith and credit of wasted computer time.” Seeing The Faithful, “Like a tribe,” he likes to think that their enthusiasm will, somehow, someday, “Help make progress towards a more rational digital currency. But, ultimately the providers of those currencies are probably going to be governments.” At this point, Borenstein argues, “No one should see blockchain technology as an end to a means. No one should look on it as a single achievement. Instead, it should be seen as a point on a spectrum. We may be long gone when bitcoin finally dies, but that doesn’t mean it’s been a success.”
David Yermack, a professor at New York University’s Stern School of Business, and director of the Pollack Center for Law and Business, believes that bitcoin resembles a speculative investment similar to the Internet stocks of the late 1990s. Writing in the MIT Technology Review, he summed up bitcoin’s problems this way: “During 2013 its volatility was three to four times higher than that of a typical stock, and its exchange rate with the dollar was about 10 times more volatile than those of the euro, yen, and other major currencies. Bitcoin’s dollar price exhibits no correlation with the dollar’s exchange rates against other currencies. Nor does it correlate with the value of gold. With a currency whose value is so untethered, it is nearly impossible to hedge against risk.”
Even if volatility subsided and bitcoin somehow found a place as a global payment system, because there can only ever be 21 million bitcoins, Yermack pointed out, it is inherently deflationary. “A fixed money supply is incompatible with a growing economy. Workers would have to accept pay cuts every year, and prices for goods would gradually fall. Such conditions might lead to public unrest reminiscent of the late 19th century’s free-silver and populist movements — an ironic consequence of a currency known for its futuristic cachet.
On the talk of losing purchasing power over the past century:
Levine shrugs that off. “Talk of 1913 dollars is completely meaningless. You need a small amount of consistent inflation because the effects of deflation are so awful. Why is everyone holding onto their bitcoins instead of spending them or lending them? Because they think it will be worth more. Back in the 1800s, people put cash in the mattress because nobody was managing the currency and there were no credible markets, except in Britain. These days, only a nitwit puts cash in the mattress.” He throws back at them the classic dilemma that the Founding Father’s faced in the 18th century – the bankers versus the farmers. “Historically, the bankers wanted hard money, which meant gold, so that their dollar denominated assets would become ever more valuable. The farmers, who were always in debt, wanted cheap money, which in the 1800s meant silver, because they wanted some inflation so they could pay off all their loans. This argument starts with Hamilton and basically doesn’t end until we get off the gold standard. Bitcoin is a world where everybody wants to be a banker and nobody admits he’s a farmer.”
Is it similar to how the internet evolved?
I then asked Borenstein what he thought about The Faithful’s often quoted comparison – that the birth and development of bitcoin mirrors the birth and development of the Internet. He wasn’t having any of it. “The Internet was designed by the most open process known to man, there’s not even an organization behind it. Thousands of people are responsible for making the Internet work through endless sessions of technical minutiae where everybody agrees to do something the same way. That does not sound like bitcoin. There may be all sorts of similarities that don’t matter. The same language, the same open source modules, but I don’t see it as being anything at all like the same.” While he remains hopeful that, one day, we will see widespread use of digital currencies, he confidently predicts, “Bitcoin won’t be it. The technology must be configured in such a way as to meet the national, political and social goals of the people who are going to run that currency. You could lay that universal framework at the software level, the systems that will inevitably be out there, to make them interchangeable. If that happens, I doubt that bitcoin’s code will be very useful.”
On hype and irrational exuberance:
Tech guru John Dvorak described it perfectly in one of his columns: “The amount of money squandered during the Dot-Com era because of ‘paradigm shifts’ and ‘new economies’ is staggering. People actually believed that all retailing would be online and that all groceries would be delivered to the home as they were in the 1920s, despite changes that make delivery impractical. Who cares about reality?”
On the wisdom of trying to short exuberance:
Referring to bubbles as “spontaneous optimism,” John Maynard Keynes pointed out, “The market can stay irrational longer than you can stay solvent.”
On the difficulty of creating other derivative products:
His answer to the first question is no. His answer to the second is yes. Bitcoin mining is very expensive, he explains, and most miners barely break even. Then, because the technology is designed to produce fewer and fewer bitcoins, he is concerned with who’s going to pay for verifying each transaction? “Eventually, as the supply of bitcoin diminishes, those fees will increase to cover the cost of authenticating the transactions, and will become competitively close to the fees for international bank wires. The arithmetic is really simple. I don’t see any way around it.” Levine shares Krugman’s doubts about bitcoin as a currency – “For a while I thought it was like Pet Rocks without the rocks” – but now he wonders, “Would you be willing to take out a mortgage written in bitcoin? The volatility suggests no one would. And, what does it say about bitcoin as a currency when nobody is willing to do anything with it besides a spot transaction?”
On MintChip and building things before there is enough demand for it:
The idea of electronic payment systems has been around for a while, but it wasn’t until 1990 that it actually got off the ground. That’s when Dr. David Everett in the UK invented the first “electronic purse.” His system was called Mondex. Developed with National Westminster Bank, it was a revolutionary idea for its day. The cash was your smart card and you spent it at point of sale terminals. For a while it got a lot of attention, then eventually, fizzled out. Everett was severely disappointed.
“I’m afraid it was way before it’s time. Just too early. In hindsight, there was nothing really broken about payment systems at the time. The Internet didn’t really exist yet. Mobile phones didn’t really exist yet. The focus we had was paying at point of sale. It was very good for the merchant, but in the end it was not so for the consumer who argued, why would I bother?” A world expert on payment systems, coding theory and cryptography for the protection of data, Everett is CEO of the Smart Card Group, technical director of Smart Card News and a man who says that his mission in life is still electronic cash. “I am an enormous believer in electronic cash.” When the Canadians asked him to help them design MintChip, he jumped at the opportunity. “MintChip was almost ten years after Mondex and I was convinced about that one too.” The idea that a Mint would produce electronic cash, “Just seemed so logical,” he says. “That’s what mints do. They mint cash.” As technical architect for the project, Everett was looking to reproduce the ease would want to do, so now you’re into merchants. Maybe a big retail chain. Say Walmart. The cost of managing cash for them is quite high, and credit and debit cards carry with them transaction fees. For big merchants, electronic cash is ideal. Here’s a way of handling payments at a fractional cost of handling cash. Walmart Dollars would work very well and if they did it, everyone would follow.” Ideally, he says, whatever the next stage is, it would not be linked to a bank account or a debit card. “We need to be unconnected. In that sense it is like bitcoin because bitcoin is unconnected. But what I want to see is a real electronic object representing cash. That’s very different from bitcoin.” For him, bitcoin is, “A new form of gold. It is electronic gold. Whereas Mondex and MintChip is equivalent to real currency, a real pound or a real dollar. I think there are a lot of nice things in the bitcoin technology, but I don’t think it’s very good for cash. It doesn’t really lend itself to immediate payments. I’m surprised bitcoin has gone as far as it has.”
On the faux news that Mastercard would be adding support for bitcoin as well as a recent patent filing:
[…] assured me Mastercard wasn’t doing anything of the kind. He explained, the application was filed to protect Mastercard’s intellectual property and did not indicate any commitment to bitcoin. “There is no obligation to ever build anything that a patent application covers.” JP Morgan had done a similar thing with a payments’ patent, putting bitcoin in there, and The Faithful reacted in kind. A spokesperson for Morgan gave me much the same answer as Mastercard. Now I brought it up with Borenstein. A man who still spends a large part of every day working on patents, he says that neither company has any intention of ever accepting bitcoins. Instead, he suggests, they harbor more sinister intentions. “Every patent has to describe all the different storage technologies it might reside on. Which really means, they’re arming themselves for a possible war. Just in case bitcoin ever poses a real threat. They’ll do what they can to wipe them out.”
Over the past four years I have had a chance to live and work throughout China. This was done in the capacity as an instructor, teacher and professor at a variety of colleges and schools across the country. Along the way I have met numerous fellow travelers, international teachers and businesspersons who have worked across the wide expanse of China’s educational systems.
I say systems because there is a cornucopia of private international schools, public schools, specialized Montessori schools and a seemingly infinite amount of training centers called bǔxíbān (companies and institutions that typically offer after-school programs such as EFL, GRE, GMAT, art, business and math training). These all exist to meet the demand of an extraordinarily large population that culturally values formalized schooling for educational attainment.
For example, in 2006 there were an estimated 16.7 million students studying at 336,200 elementary schools and 21.2 million students studying at 361,300 junior high schools (the reason for the relative decline and difference in the cohort sizes has to do with the one-child policy).123 More than 9 million high school seniors take the national college examination (gaokao) each year, the top percentage of which typically then study overseas.4 And approximately 8 million college students now graduate each year in China, a rate that has quadrupled since 2002.5
In addition, as I mention below, there are a number of extra-curricular training centers called bǔxíbān that cater to the growing domestic demand for foreign educational services. For instance, in 2011 more than 20,000 Chinese high school students took the SAT as part of their quest to study overseas.67 With 58,196 test-takers from the mainland, one in five people who took the GMAT in 2011 was from China – a 45% increase from the previous year (and up from 11,000 in 2008).89 Both tests are conducted entirely in English. New Oriental Education – among many other training centers – alone trains and tests up to 200,000 students a year in standardized tests like TOEFL and SAT.1011
In January 2009, then-Premier Wen Jiabao stated that there were roughly 300 million English learners in China. For perspective, there are 600 times more Chinese studying English than Americans who study Mandarin.12 From primary school through the first two years of college, nearly every student in China is required to take English. One of the subjects tested during the gaokao, the annual national college entrance exam, is English. And with great commitment comes great costs. In 2002 the estimated price tag on EFL education was $1.4 billion and according to a 2009 McKinsey & Company report, “China’s foreign-language business is worth $2.1 billion annually.”13 As I mention below, this is substantially lower (5x) than their peers such as Japan and South Korea.
Who teaches these EFL courses? According to People’s Daily, approximately 100,000 foreign teachers and experts are recruited each year to work on the mainland.1415 But before jumping on a plane and starting a new EFL division of your company overseas consider that not only would you need various licenses to start up a new firm, but that the EFL market is already sorting the wheat from the chaff.16 For example, a large number of nation-wide EFL providers including: Disney English, Wall Street English and English First (EF) are owned and operated by foreign companies. EF is actually the world’s largest EFL company, with 34,000 employees and more than 500,000 paying students globally. New Oriental Education and Ambow Education were both founded by Chinese nationals.17 They rank among the top EFL providers in China and are even traded on the NYSE.
So like all business startups, be sure to do a SWOT (strengths, weaknesses, opportunities, threats) analysis and identify what your company can provide that is not already being serviced. Even with these well-funded incumbents, a case could be made that entrepreneurs (both foreign and domestic) can still create a profitable business model, catering to specific niches (e.g., first-contact health care providers, hospitality managers, financial and securities traders, lawyers and paralegals).18
While some have argued that EFL might be bubble activity, there is arguably a lot of organic, bottom-up support for this drive into English. For instance, according to Jun Liu, English professor at the University of Arizona, as of 2007 about “40,000 foreign companies have been set up within China and employ 25 million people.”19 As a consequence a lot of the day-to-day operations are conducted in English, such as emailing, accounting, finance and sales. And this outward push from within organizations can be illustrated by firms such as Air China – the third largest carrier in China – which has introduced an incentive program for its employees to learn English from a large TEFL provider. Similar incentive programs exist at foreign-owned multinationals such as Eli Lilly, Metro (a large German supermarket chain) and Intel. On a governmental level, in a bid to help tourists and foreigners, one such firm – English First – was even hired to teach taxi drivers and volunteers during the Shanghai 2010 Expo; they were also the official trainers for the 2008 Beijing Olympics.
And with a goal of becoming distinguishable and eventually an international brand, most businesses and large SOEs have adopted English names such as China Unicom, Lenovo, Agricultural Bank of China, China National Petroleum, State Grid and China Railway.2021 As I mention later in Chapter 12, this push outward presents an opportunity for US companies and institutions to help market and educate Chinese firms looking to do business overseas. On this note, in June 2012, Shaun Rein, the author of “The End of Cheap China,” made the case that China will continue to need American education and American educators.22 He makes a persuasive call for US-based educational entrepreneurs as well as educational companies and institutions to set up shop on the mainland. And if you do not, someone, perhaps even your competition will.
What you and your firm can do
For perspective, South Korea, which invests more on EFL education than any other country, collectively spends between $10-$15 billion a year on EFL education; one 2005 estimate put the figure even higher, 1.9% of GDP (approximately $16 billion).23 And with a number of domestic programs similar to its neighbors, Japan spends about $8 billion a year on EFL.24 Thus with a population ten times the size of Japan and a GDP six times the size of South Korea, there is a lot of potential room for EFL growth in China, which as noted above, spent $2.1 billion on EFL in 2009.
How much do these programs at a language center typically cost? I spoke with a high level Chinese manager in charge of operations at a large EFL training center in Pudong, Shanghai who has had 20 years of experience working at Disney English, Wall Street English, EF, Web English and Huapu (the latter two are Chinese-owned and managed). According to her, “ten years ago it was a seller’s market as there were relatively few language centers and as a consequence they could charge enormous tuition fees, upwards of 400,000 RMB [$64,000] a year primarily because there was and still is a large demand for authentic face-to-face experiences. In return the centers provided one-on-one intensive training with laowai – native English speakers – for hours each day. Today, because the market has matured over the past decade, the average high-end language package now costs about 30-40,000 RMB [$4,800-$6,400] annually in larger cities like Shanghai and Beijing – which is still a somewhat high amount considering the annual wages for most urban residents is less than $9000 a year. Yet, there still a number of firms such as RISE and baite (百特英语) that specialize in providing English-only, total immersion environments for their customers – at a substantial cost.”
One of the ongoing issues that any service provider in any country must continuously deal with is figuring out the right price point for attracting potential customers. Online education is one way to create flexible rates; as a consequence several EFL programs are now available at substantially lower costs compared with ten years ago (e.g., 500 RMB per month). Another example is while the value of an EFL package is subjective based on each individual’s preferences, there are ways to make repayment easier.25 Take for instance, payment plans. At some language centers they are now allowing customers to pay by installment. And according to this same source, even though 10-20,000 RMB [$1,600-$3,200] a year is now considered a “reasonable sweet spot” in the mind of the typical middle class worker in a Tier 1 city; some of these consumers still would like flexibility and assistance and thus providing month-to-month billing allows them to achieve a win-win compromise.
Catering to specific clientele
In November 2012 I spoke with Cathy Su, a six-year marketing veteran at English First (EF) and Fujian native, about education-related business opportunities in China. According to Su, “parents will go to great lengths to sacrifice themselves for their child’s educational future. For example, in order to send their children overseas, many are essentially price inelastic. Some are willing to invest and spend substantial amounts in order to help their children get an overseas education. They do this for multiple reasons, yet in every case, the students all need both coaching and training to prepare for standardized tests like the SAT, GMAT and TOEFL in order to matriculate overseas.”
While there are cultural components (such as li or 禮) to this seeming inelasticity one of the key issues that Chinese families currently face is as Charles Zhang (the founder of internet giant Sohu) recently explained in an interview,
“I believe the US system is definitely better than the Chinese system. First of all, China just has way too many people. The entire system becomes very competitive and thus opportunities are limited. Education in China is not education; it is selection. Of course, the biggest selection process is the national college entrance exam, the Gaokao. The Chinese system naturally must prepare children to study for this inevitable exam, but the preparation is the complete destruction of creativity.”26
Zhang’s comments were similarly echoed by Paul French, the Chief China Market Strategist at Mintel who recently noted that, “[t]here simply aren’t enough places at enough good universities for all the Little Emperors capable of attending and passing the required exams.”27 Little Emperors (八零後) are single children born and raised under the one-child policy. And due to this confluence of scarcity and demographic pressures, this ultra-competitive labor market has motivated parents to push their only child to accumulate other degrees and certificates (see below). For example, according to a report from Mintel, “three-quarters of middle-class Chinese parents expect their child to earn a postgraduate degree, while only 32% said they would be happy if their child stopped at the undergraduate level.”28
This sentiment was similarly noted by Wendy Bao, with whom I also spoke in November 2012. She is originally from Zhejiang and has worked throughout EF over the past 10 years in positions such as a product manager, market analyst and in business intelligence. According to Bao, “Chinese parents care more about education for kids than themselves. Or rather, if there was an investment decision between the two, Chinese parents will invest more in their children’s education and extracurricular activities because they see their progeny as more important than their own personal achievements.”
Such sacrifice is illustrated by the family of Wu Caoying, who now attends a three-year polytechnical school. Growing up in Shaanxi province, she is the only child of her parents. Her father works in a coal mine, earning $500 a month and her mother earns $12 a day “tying little plastic bags one at a time around 3,000 young apples on trees, to protect them from insects.”29 Together they have scrimped and saved for their daughters education and spend more than 50% of their monthly earnings so that their daughter could attend a boarding school during high school and can now matriculate to the polytech. In return, Caoying is expected to help take care of her parents after they retire.
While part of the education-centric ethic stems from various Confucian teachings (e.g., xiushen or修身) that most Chinese are taught from a young age another reason why foreign degrees are sought is that this highly competitive labor market has led to credentialism (e.g., obtaining a certificate or degree merely to collect it for your resumé and CV).30 As a consequence Cathy Su also thinks that because of this education ethic, that in addition to traditional EFL training there is essentially an insatiable demand for niche services such as SAT coaching. This may be especially true since the middle class is expected to grow from 300 million today to an estimated 600 million by 2020.31 And as I noted in Chapter 6, with a growing middle class comes growing disposable incomes. Furthermore, wealthier Chinese families are increasingly looking to send their children abroad in part because of the hyper competitive domestic climate and due to the perceived creativity-friendly environment at Western institutions. For example, a 2012 report from Hurun regarding high net worth individuals (there are approximately 2.7 million HNWI in China), “85% plan to send their children abroad for education.”3233
And what do these Chinese students do after completing their degrees? While many of them obtain permanent residency, others return to the mainland (see ‘brain drain’ in Chapter 19) as future innovators and policy makers. For instance, several of the largest internet companies in China were founded by Chinese nationals who attended US institutions for college and graduate school. Charles Zhang (Sohu) graduated from MIT; Robin Li (Baidu) graduated from SUNY Buffalo; Joseph Chen (Renren) graduated from University of Delaware, Stanford and MIT; Gary Wang (Tudou) graduated from Johns Hopkins and the College of Staten Island; James Liang (Ctrip) graduated from Georgia Institute of Technology; Victor Koo (Youku) graduated from Stanford and UC Berkeley; and numerous executives in the management teams at Sina and Tencent attended a US college. In addition many others at Alibaba attended other Western institutions or joint ventures like the China Europe International Business School, the first business school to offer an MBA on the mainland.3435 Harvard has several programs designed specifically to educate and facilitate information exchange with future Chinese policy makers. One of its programs called China’s Leaders in Development brings in “50 to 60 official each year.”36 Its Kennedy School has trained 150 Chinese officials since its program began in 1998. All told about half of the 668 Chinese students in the 2012-2013 school year at Harvard are enrolled in the Graduate School of Arts and Sciences.37
In fact, while the legal issues are still being sorted out, there may be opportunities for both non-profit and for-profit traditional brick-and-mortar schools in larger mainland cities. For example, many Chinese families are faced with a dilemma in terms of educational options on the mainland. On the one hand they can send their children – or usually the only child – to public schools. While some of the public schools are opening special classes for students wanting to study abroad (SAT, AP, A-level prep), public schools are usually considered substandard due to lack of funding and rote memorization learning methods. Another viable choice is for families to try and help send their kin overseas yet this is financially cumbersome to most middle-class families.38 A third option is private schools, yet there are currently very few private schools on the mainland, thus the other two options above place many families in an uncomfortable bind (e.g., they would like their children to receive the best education possible but have limited choices).
This may be changing however. Two years ago Wellington School, a 150-year old British school, was replicated in Beijing.39 For £15,000 a year ($23,800), Beijing parents can now send their children to this new school based on the British public school system. Oxford International College (unrelated to Oxford University) charges up to $41,700 a year in its private schools located on the mainland and also emulate the British education system.40 And while it take some time before such imports are more widely accepted, the only other alternative currently is international schools, though while relatively popular, they are also both very exclusive (you typically need to have a foreign passport to be eligible) and prohibitively expensive ($10,000-$35,000 a year).41 Yet the trend towards international schools is growing. According to Reuters, there are now 338 such schools (up from just 22 twelve years ago) whom collectively enroll 184,073 students.42
Or conversely perhaps your firm can help place Chinese students in American schools. For example, according to the Association of Boarding Schools, “about 5,600 students from China [are] enrolled in its 285 member schools in the US this academic year [2012-2013].”43 According to the US Department of Homeland Security, in 2010-2011 the amount of Chinese students studying at private schools in the US was 6,725, up from 65 in 2005.44 In terms of costs, some international programs like Leman Manhattan Preparatory School in Manhattan cost $68,000 a year (30 out of the 40 international students at Leman are currently from China).45 Other boarding schools in the New York metro area cost an average of $46,875 a year. As a consequence, the opportunities for foreign experts and entrepreneurs looking to wade into both sides of the market may be viable, even for administrative tasks.
For instance, US institutions and organizations collectively spend $980 billion annually on education, twice as much as China.4647 Due to a variety of factors including large spending per capita, US institutions continue to attract foreign talent. For example, there were 765,000 foreign nationals studying in the US in 2011 – including 158,000 Chinese (there are now 194,000 Chinese studying in the US).4849 And according to the US Department of Commerce, these foreign students contributed $22.7 billion to the economy and many stay after graduation (Chinese students alone added $5 billion to the US economy in 2012).50 Thus in an effort to improve both the quantity and quality of its graduates as well as raise its standing on league tables and rankings, every level of the Chinese government is implementing plans to invest ever larger sums of funds into education; including recruiting foreigners (for comparison, 24,000 Americans studied in China in 2011).51
Yet, with the administrative, marketing and teaching prowess gained from over six decades of being at the top of the international educational marketplace, managers and entrepreneurs at US institutions could conceivably capitalize on their skill bases and leverage them in China’s expanding market.5253 A year ago, in March 2012, Stanford University opened the doors to a new joint venture, Stanford Center at Peking University making it one of the first permanent higher education facilities to open on a Chinese campus.54 NYU has set up the first Sino-US joint venture university that will award a double bachelor’s degree (from both the local Shanghai branch and NYU in Manhattan). Classes began in the fall of 2012 and students from the mainland will pay 100,000 RMB ($15,948) a year to attend.55 And Julliard, the performing arts conservatory, is building a campus in Tianjin (southeast of Beijing) catering to students aged 8 to 18.56
At the same time however, enthusiasm should be tempered as a joint Yale University – Peking University undergraduate program “collapsed” this past July due to “high expenses, low enrolment and weaknesses in its [Yale] Chinese-language programme.”57 Similarly, Duke University’s venture with Wuhan University has run into several major problems. The construction of the new Duke Kunshan joint campus has been delayed five times over the past three years due to “slow” and “shoddy” workmanship.58 Thus success in this segment is not necessarily a foregone conclusion.
Another role that foreign administrators may be able to utilize is that of an agent, or admissions consultant. According to one estimate, “8 out of every 10 Chinese undergraduate students use an agent to file their applications.”59 These agents in turn will help candidates fix their admissions essays, find the best references to write recommendation letters and otherwise guide clients through a streamlined process to foreign-based colleges.60 Maybe you and your company can utilize your expertise to work with new clientele.
However, as touched on above, the mainland education industry can also be tricky. For example, in order to be granted a license, certifications have to be recognized by the Ministry of Education.61 Online-awarded degrees and certifications are typically not accredited by the Ministry. As a consequence you may have to set up a physical brick-and-mortar office in order to do business within the Chinese marketplace. In addition, alternative certification programs such as Microsoft’s MCSE, Cisco’s CCNA, Huawei’s HANA and others like Certified Nutritionist are increasingly prevalent – so as long as they are recognized by what the Ministry deems as a legitimate institutional authority.
For instance, what if your company trains and educates workers in an ISO management process in the US? If you wanted to expand into China you may need to reinvent your firm on the mainland by creating a brick-and-mortar office location before you can legally market within China. A consequence for failing to do so would be the trials faced – according to a source at the company – by the University of Phoenix, which despite its 35 years of history, was originally not seen as a legitimate degree awarding institution in China.
National Quality Assurance (NQA) is one of the largest ISO registrars in the world and an Accredited Certification Body (ACB) that coordinates with regional sub organizations to train, audit and certify organizations and companies in ISO 9000 family of quality management certifications. SNQA is the organization in charge of verifying, confirming and auditing ISO 9001, ISO 13485, TL9000, BRC-CP and several other standards on the mainland.62 In January 2013 I spoke with Jason Jia, who is managing the new Wuhan, Hubei office for SNQA. Jia is originally from Anhui but has spent the last 3 years working in sales for SNQA. He noted that, “there are long-term opportunities for foreign ISO experts that can provide to mainland firms such as training and auditing services. However one of the challenges facing these same companies is that communication issues are usually a big problem. In addition, the maintenance and foreign labor overhead expenditures relative to local labor are usually cost prohibitive and as a consequence the daily maintenance fees are typically so high that most Chinese firms cannot afford it. For example, we as a certification organization pay the auditor company a daily training and on-site verification fee and this quickly adds up when taking into account the relatively higher per hour costs charged by foreign companies.”
One lively human resource area within the education labor market provides large compensation packages yet has relatively few candidates: if you have internationally recognized awards, Chinese institutions will hire Western superstar teachers to improve their table rankings.63 For example, three years ago Jiao Tong University in Shanghai scored a coup, recruiting French virologist Luc Montagnier, who discovered HIV and subsequently received the Nobel Prize in 2008. Another case is, Rao Yi, who grew up in China but spent 22 years at Northwestern University before being lured back to become the dean of Life Sciences at Peking University.64 All told, the Chinese national government in a project dubbed the “1,000 talents program” (see more below in Chapter 15) is offering perks and bonuses up to $150,000 in an attempt to lure “foreign-educated Chinese scientists, academics, financial experts, and M.B.A.s.”65 And according to Wang Huiyao, head of the Center for China and Globalization, approximately 15,000 individuals have come to the mainland through this program.66
At the same time, if your goal is acting as an intermediary and talent recruiter, expectations should be tempered with a dose of reality. For example, Pat Sullivan, an accountant and chairman of international recruiting at Young Harris College told me in March 2013 that there are a number of obstacles created by current US immigration policies, which put numerous roadblocks in the way of foreign students seeking to study in the United States. According to her, “The paperwork required for US Visas, health certificates, assurances of financial solvency, and other forms are always more time consuming than one would expect. Planning for the arrival of foreign students must begin months in advance and requires the active participation and assistance of the host educational institution.”
Consequently, for those entrepreneurs looking to open up a new seminar or class room system, several questions need to be answered: where will you find customers who are willing and able to pay? How will you build, manage and incentivize a sales force team to convert leads into customers? Who will teach and design the curriculum for the courses? Where will these seminars and courses be held?
In terms of taxes, there is one other challenge for foreign-owned companies that is not entirely unique to the EFL industry, yet should be recognized and addressed. As mentioned above, each province has its own legal requirements for business licenses and certifications.67 For example, in Shanghai, in addition to a college degree a foreign teacher is required to have at least 2 years of previous teaching experience as well as a TEFL certificate from an authorized institution. On the business end, due to relatively strict capital controls (e.g., individuals are limited to $50,000 in transfers annually) it can be relatively complex to repatriate your profits and assets from schools as there are also numerous taxes, tariffs and levies that do and do not apply specifically to educational companies. While not explicitly discouraged, creative accounting, subcontracting and the “Hong Kong shuffle” (see Chapter 10) have become increasingly popular tactics by EFL firms to reduce tax liabilities.6869 Thus it is recommended that you speak with an attorney or tax expert before you invest in a new EFL program.
In terms of educational activities irrespective of being indoors or outdoors, according to its September 2012 report, Distimo noted that the popularity of English-based apps in China for the iPhone still remains very high.70 It is the 2nd largest installed language for apps overall and thus foreign entrepreneurs – including those in the education industry – may be able to turn this embedded built-in language base to their advantage. Because the userbase is already largely familiar with Romanization, that is one less problem to be concerned with. You might consider creating online virtual EFL classrooms based on apps for smartphones and tablets or rolling out cloud-based video courses that can be viewed by anyone with an internet connection.
In fact, one point Wendy Bao explained to me was that online classes and programs like Khan Academy will be the future of education. Khan Academy is a popular non-profit educational organization that focuses on making micro lessons on a variety of topics and has delivered more than 200 million lessons online.71 In Bao’s words, “while online courses may have a slower uptake in China due to a limited – yet growing – telecommunication infrastructure, because of their inherent flexibility for being offered and accessed throughout a wide variety of time slots, this will enfranchise rural and urban students who can now utilize global knowledge databases. These same students – who due to their inland locations and schools lacking the funds would otherwise not have access to experts including foreign instructors whose language skills are highly sought after and could be substantially cheaper via telepresence.”
Yet again, one challenge, as Bao mentioned, is that the telecom infrastructure is still relatively limited in bandwidth. For example, as I note later in Chapter 15, according to their Q3 2012 speed survey, ChinaCache, the largest domestic content delivery network (CDN),notes that while the overall speeds are a little slower than previous speed rankings, Shanghai currently leads the country in average speeds at roughly 3.44 Mb/s and Beijing is 10th at around 2.5 Mb/s.7273 Akamai Technologies (a global content delivery network provider) ranked China’s average internet-connection speed at 94th globally, at 1.6 Mb/s.74 In addition, depending on the regulatory and monitoring issues discussed in Chapter 20 with the Great Firewall, quality of service and bandwidth may decline as you leave the larger Tier 1 cities. Thus entrepreneurs should take these factors into account while making a business plan.
In December 2012 I spoke with Eric Azumi, vice-president of information systems at EF. According to him “the online market is just now beginning to be tapped.75 There have been limitations that continue to be overcome including computational and bandwidth issues that arise in every country but especially in China. Voice recognition services similar to Siri will probably be the next technology incorporated into this segment and eventually, as the online industry matures, it will be commoditized. What I mean by that is that at some point all competitors will have very similar software stacks in terms of features and functionality, yet there is always room for value-added services – especially as more direct-teacher training is replaced with mobile learning.”
Azumi gives as an example, the technical changes over the past 15 years as online classrooms evolved from text-only, to incorporate audio, then video via telepresence (e.g., webcams) and as he predicts in the near-term, real-time voice recognition. Yet again even with all of these competitive forces with large, well-funded, experienced incumbents he thinks that “because of the relatively low barriers to entry just about anyone can still set up an educational center in China and elsewhere, especially if they cater to niche groups or provide a unique environment such as how coffee shops in Japan have been turned into English conversation centers that provide both relaxed and informal way of improving language skills. And because people by-and-large still insist on face-to-face time, the general acceptance of online education will take time to diffuse here and around the globe. Furthermore even with the advent of on-demand instructional services there are still many opportunities for traditional schools in 2nd & 3rd Tier cities which are still nascent markets that have not been exploited yet.” These technological challenges and opportunities related to cloud computing are further expanded on in Chapter 13.
Yet for those willing to face these technical challenges, the financial rewards could be lucrative. According to one recent estimate, up to 380 million people in China will “need high-quality education and training resources across the country” from 2012 to 2017.76 And a large percentage (~30%) of these people are expected to utilize online services and tools, creating a potential market worth an estimated $11 billion in revenue. However, to temper any get-rich-quick enthusiasm, the amount of investment into Chinese education companies fell to $46 million in 2012, less than a quarter of the previous year.77 Why? David Chen of AngleVest – a venture capital group focusing on angel rounds – noted that “the timeframe for growing an education business can be drawn-out, and a challenge for fund managers who have to achieve returns by a specific date.”78 Thus once again, while there is potential revenue there is also required patience for returns on investment.
Takeaway: The education market in China has the potential to be both large and profitable. However, gone are the days when you could merely jump on an airplane, get off and instantly set-up a market-leading company. The industry has become increasingly competitive with both professionalized workforces and various rules and regulations such as licensing and certification guidelines. But as long as the Chinese economy and population continue to grow, there should be continued opportunities for entrepreneurs and companies who have done their due diligence. This chapter does not discuss guanxi, a cultural phenomenon involving personal connections within the hiring and deal making process in all Chinese business transactions. But that is a very complex topic worthy of several copious volumes and touched on in Chapter 10.
More specifically, “Despite a 40% increase in population since 1976 the number of primary school students has gone down by 33%, from 150 million to 100 million, and there were half as many primary schools in 2010 as there were in 2000.” See 停止计划生育政策的紧急呼吁 from Eduzx.net [↩]
Currently there are no SAT test centers on the mainland due to restrictions by the government. Thus students wanting to take the SAT must go elsewhere, typically Hong Kong. See ”洋高考”来势凶猛国内高校面临挑战 from Sohu [↩]
This growth in GMAT testing and overseas matriculation is one of the reasons why US institutions that provide MBAs have grown from 26,000 to more than 168,000 annual graduates from 1970 to 2009. There are a number of mainland based MBA schools as well including the top ranked Cheung Kong Graduate School of Business in Beijing. See Is the MBA Obsolete from Forbes, China Best Business School Leadership MBA from Forbes and Game Changers: Guanghua Cai from Fortune [↩]
As I note in Chapter 14, through the mass consumption of Western entertainment, the Romanization and Latinization of both mainland businesses and cultures continues. And yet this is not the only area in which Western culture is absorbed on the mainland. According to Yasmin Haskell, “The Chinese already appreciate the importance of these sources [European sinologists]. Several years ago they were sending local students on scholarships to learn Latin at European universities. Today, as I am reliably informed by a senior American colleague, they are training up thousands of Chinese teachers of classics – not the Chinese classics of Confucius and Lao Tzu, that is, but those of ancient Greece and Rome.” See We must look to an ancient tongue to understand Asia from The Australian [↩]
Another on-going long-term opportunity for brand marketers is working with these large SOEs as they internationalize and go abroad. While they typically dominate their specific market segments domestically (in part because of their monopolistic privilege) they have had uphill challenges in expanding abroad. See BCG: Chinese State-Owned Firms Not So Muscular Abroad from The Wall Street Journal [↩]
As one of my Chinese mentors in Singapore explained, the cultural component should not be overlooked or downplayed. There is a Confucian virtue called xiushen (修身 or self-cultivation, improvement, rectification) which has been enshrined at a deep cultural level across the Chinese populace that Western education, especially at tertiary levels, and particularly in the fields of science, technology, management, marketing and finance will probably see strong demand for years to come. This is not simply a calculation concern (to improve one’s income potential), but even more so a cultural phenomenon. [↩]
Some of these new “special” programs (preparatory courses often taught by foreigners) are called “American-Chinese cooperation programs” and are being implemented at public schools, yet they also have their own admissions hurdles. For example, they all require their own entrance examination and some of these programs charge up to 100,000 RMB ($15,000). See “洋高考”来势凶猛国内高校面临挑战 from Sohu [↩]
It is not just US colleges that have benefited from this international student pool. According to an Al Jazeera report, “British universities receive more students from China than any other country outside of the European Union.” There were 67,235 Chinese international students in the 2010-2011 cohort in the UK. See Chinese students choosing to study abroad from Al Jazeera [↩]
Prior to World War II, the leading institutions of both the sciences and social studies were in German-speaking countries. German, not English, was the lingua franca of the academic world for nearly a century. [↩]
While there are many genuine applicants, foreign admissions consultants should be aware that considerable amounts of fraud have taken place in this subindustry. In fact, one report in 2011 based on a survey of 250 Beijing high school students matriculating to the US “concluded that 90 percent of Chinese applicants submit false recommendations, 70 percent have other people write their personal essays, 50 percent have forged high school transcripts and 10 percent list academic awards and other achievements they did not receive.” See A Chinese Education, for a Price from The New York Times, The China Conundrum from The New York Times and Busted: Fraud in China by Tom Melcher [↩]
