Blockstream’s sidechain’s is announced

I just finished reading through the new sidechains paper (pdf).  The team has clearly been thinking of clever solutions to a multitude of challenges.

Below are my first thoughts which could change as more information is released and/or code is implemented.

The biggest issue they did not address (so far) is how to incentivize mining after block reward halvings, though that probably was not their intent.  Also, and again this is just day one, but it is also unclear if the IP will be released as open source and if someone could use that code to create Blockstream 2, 3, etc.?

My comments below each block quote:

Because the miners do not form an identifiable set, they cannot have discretion over the rules determining transaction validity. Therefore, Bitcoin’s rules must be determined at the start of its history, and new valid transaction forms cannot be added except with the agreement of every network participant.

Even with such an agreement, changes are difficult to deploy because they
require all participants to implement and execute the new rules in exactly the same way, including edge cases and unexpected interactions with other features.

How can this be done in a trustless manner? Mining was supposed to be anonymous.  If they are identifiable by good actors, then they’re also identifiable by bad actors and not-so-good actors.

One problem is infrastructure fragmentation: because each altchain uses its own technology stack, effort is frequently duplicated and lost. Because of this, and because implementers of altchains may fail to clear the very high barrier of security-specific domain knowledge in Bitcoin[Poe14c], security problems are often duplicated across altchains while their fixes are not. Substantial resources must be spent finding or building the expertise to review novel distributed cryptosystems, but when they are not, security weaknesses are often invisible until they are exploited. As a result, we have seen a volatile, unnavigable environment develop, where the most visible projects may be the least technically sound. As an analogy, imagine an Internet where every website used its own TCP implementation, advertising its customised checksum and packet splicing algorithms to end users. This would not be a viable environment, and neither is the current environment of altchains.

Non sequitur.  The same complaint could be leveled at German carmakers versus American carmakers with the fragmentation in something like unit of measurement (meters vs Imperial).  The auto industry did not collapse because of fragmentation.

In addition, there is fragmentation within Bitcoin itself, with different pools relaying different types of transactions (or censoring others).  A couple days ago Dominic Williams pointed this out (in a different email), that there are different payment processors and different wallets that are incompatible (you can send money between them, but you can’t open one wallet with another).

A second problem is that such altchains, like Bitcoin, typically have their own native cryptocurrency, or altcoin, with a floating price. To access the altchain, users must use a market to obtain this currency, exposing them to the high risk and volatility associated with new currencies. Further, the requirement to independently solve the problems of initial distribution and valuation, while at the same time contending with adverse network effects and a crowded market, discourages technical innovation while at the same time encouraging market games. This is dangerous not only
to those directly participating in these systems, but also to the cryptocurrency industry as a whole. If the field is seen as too risky by the public, adoption may be hampered, or cryptocurrencies might be deserted entirely (voluntarily or legislatively).

Why are floating prices considered a bad thing?  Besides, the issues in this paragraph are exactly the same problem bitcoin faces each day and a solution to risks/volatility is not addressed in this white paper.  See Ferdinando Ametrano’s paper as well as Robert Sams’ upcoming draft on Seigniorage Shares.

Our proposed solution is to transfer assets by providing proofs of possession in the transferring transactions themselves, avoiding the need for nodes to track the sending chain. On a high level, when moving assets from one blockchain to another, we create a transaction on the first blockchain locking the assets, then create a transaction on the second blockchain whose inputs contain a cryptographic proof that the lock was done correctly. These inputs are tagged with an asset type, e.g. the genesis hash of its originating blockchain.

This has me thinking about token history and fungibility.  Perhaps it could be argued that moving these coins to a sidechain is an act of “mixing.”  Are atomic swaps a form of mixing?

Also, if the proof-of-burn effectively means “deposits” (from one chain to another) and value transfer is taking place, is this impacted by regulations such as 12 U.S. Code § 1831t – Depository institutions lacking Federal deposit insurance

This is true for almost all aspects of Bitcoin: a user running a full node will never accept a transaction that is directly or indirectly the result of counterfeiting or spending without proving possession. However, trustless operation is not possible for preventing double spending, as there is no way to distinguish between two conflicting but otherwise valid transactions. Instead of relying on a centralised trusted party or parties to take on this arbitration function like Bitcoin’s predecessors, Bitcoin reduces the trust required — but does not remove it — by using a DMMS and economic incentives.

It is still unclear what the additional economic incentives will be in the Blockstream/sidechains model.  Is it just the fees in section 6.1, such as the clever time-shifting mentioned later on?

This gives a boost in security, since now even a 51% attacker cannot falsely move coins from the parent chain to the sidechain. However, it comes at the expense of forcing sidechain validators to track the parent chain, and also implies that reorganisations on the parent chain may cause reorganisations on the sidechain. We do not explore this possibility in detail here, as issues surrounding reorganisations result in a significant expansion in complexity.

What are the costs of running and maintaining this validator?

No reaction. The result is that the sidechain is a “fractional reserve” of the assets it is storing from other chains. This may be acceptable for tiny amounts which are believed to be less than the number of lost sidechain coins, or if an insurer promises to make good on missing assets. However, beyond some threshold, a “bank run” of withdrawals from the sidechain is likely, which would leave somebody holding the bag in the end. Indirect damage could include widespread loss of faith in sidechains, and the expense to the parent chain to process a sudden rush of transactions.

Who determines insurance of a blockchain?  Will FDIC or similar bodies have jurisdictional grounds as described in the above USC citation (not a joke, Blockstream founders are not anonymous nor most large farm & pool operators)?

As miners provide work for more blockchains, more resources are needed to track and validate them all. Miners that provide work for a subset of blockchains are compensated less than those which provide work for every possible blockchain. Smaller-scale miners may be unable to afford the full costs to mine every blockchain, and could thus be put at a disadvantage compared to larger, established miners who are able to claim greater compensation from a larger set of blockchains.

We note however that it is possible for miners to delegate validation and transaction selection of any subset of the blockchains that they provide work for. Choosing to delegate authority enables miners to avoid almost all of the additional resource requirements, or provide work for blockchains that they are still in the process of validating. However such delegation comes at the cost of centralising validation and transaction selection for the blockchain, even if the work generation itself remains distributed. Miners might also choose instead to not provide work for blockchains that they are still in the process of validating, thus voluntarily giving up some compensation in 360 exchange for increased validation decentralisation.

How can that be done trustlessly?  How does that deal with the issues Dave Hudson talked about with respect to IHPP in general?  Until IHPP is changed or modified, Hudson’s models will remain valid.

By using a sidechain which carries bitcoins rather than a completely new currency, one can avoid the thorny problems of initial distribution and market vulnerability, as well as barriers to adoption for new users, who no longer need to locate a trustworthy marketplace or invest in mining hardware to obtain altcoin assets.

This doesn’t seem to be addressing several other reasons for why alts exist: who will pay independent developers wanting to build on sidechains? What about non-SHA-based hardware (like scrypt or X11)?  What is to prevent someone from forking “sidechains” code and creating a similar business?

An alternate mechanism for achieving block rewards on the sidechain is demurrage, an idea pioneered for digital currency by Freicoin (http://freico.in). In a demurring cryptocurrency, all unspent outputs lose value over time, with the lost value being recollected by miners. This keeps the currency supply stable while still rewarding miners. It may be better aligned with user interests than inflation because loss to demurrage is enacted uniformly everywhere and instantaneously, unlike inflation; it also mitigates the possibility of long-unspent “lost” coins being reanimated at their current valuation and shocking the economy, which is a perceived risk in Bitcoin. Demurrage creates incentives to increase monetary velocity and lower interest rates, which are considered (e.g. by Freicoin advocates and other supporters of Silvio Gesell’s theory of interest[Ges16]) to be socially beneficial. In pegged sidechains, demurrage allows miners to be paid in existing already valued currency.

I am not sure Freicoin is a particularly good example here because in practice few participants want an asset to always lose value (what investors actively demand demurrage?).  Maybe this is reflected in its lack of adoption (thus far).  Perhaps that will change, perhaps Freicoin will grow over the course of the next few years. But this also touches on the issue of whether or not these “coins” are commodities or a currency in the first place (I have argued they are informational commodities).

The point about reanimation is an interesting one (and good) because of the uncertainties of “zombie” coins (as John Ratcliff calls them) that jump back onto the market.

Also, while the experimentation use-cases in section 5.1.1 seem to have some active demand (as measured by crowdsales and hype this past year) they could also (IANAL) lead to legal issues that these 2.0 projects are having with respect to unregistered securities (see the SEC with its Howey test).  This is a legally risky area as discussed by these lawyers.  Also, if users can create digital tokens pegged to real world assets — if these are non-deliverable, does this turn that chain into a large “bucket shop“?

Co-signed SPV proofs. Introducing signers who must sign off on valid SPV proofs, watching for false proofs. This results in a direct tradeoff between centralisation and security against a high-hashpower attack. There is a wide spectrum of trade-offs available in this area: signers may be required only for high-value transfers; they may be required only when sidechain hashpower is too small a percentage of Bitcoin’s; etc. Further discussion about the usefulness of this kind of trade-off is covered in Appendix A.

Who will maintain these?  No Free Lunch.

Fintech in the news #1

I am retiring the previous list name “Cryptocurrency in the news” because I think that fintech (financial technology) is a more accurate, all encompassing term for this space.  There are other possible names like “dapps” (decentralized applications) however I prefer fintech because decentralization may not be what the market chooses as an end game.

Traffic analysis from Sarah Meiklejohn

Sarah Meiklejohn is a researcher now at UCL.  She is probably best known for her authorship of one of the best research papers in the digital currency space: A Fistful of Bitcoins: Characterizing Payments Among. Men with No Names.

She recently gave a presentation covering this paper (which admittedly has older data) and talks about some of the new privacy projects like CoinJoin which she says had a noticeable impact on a heuristic used in the study.  The Q/A session at the end also has some good comments.

Cryptocurrency in the news #30

When digital archeologists peruse Reddit in 20 years, to look at what happened to the Bitcoin community, it is posts like this pumper that will serve as a case study — an exhibit of how false information was used to promote adoption.  As shown in the comments, the Klarna Group is not in fact adopting Bitcoin.  It is unclear who is behind these type of posts, but it is unfortunately very common.

Thoughts on the 2.0 space

I recently became a mentor for Koinify, a venture-backed company based in Mountain View. CoinDesk reached out and asked several questions related to the startup and published a few of the comments in a story, “Crypto 2.0 Roundup: The Overstock Effect, Counterparty Debates and a Crypto iTunes.

Readers may be interested in a few more of my thoughts below.  Disclosure: there is no financial compensation for the mentor role.  Furthermore, I am also an advisor for Hyperledger and head of business development at Melotic.

  • As of today, Koinify is probably the only serious venture-backed startup that solely focuses on building decentralized applications and decentralized autonomous corporations (DACs).   It is also setting some ‘best-practices’ in transparency that has been largely missing in this community.  You will see that soon with Koinify’s following announcements.
  • The biggest problem in the altcoin/decentralize app space is that virtually all of them lack any original utility, are blatant scams or simply cannot fulfill the paper-based promises of their vocal promoters.  In short, virtually all digital asset projects have thus far been overpromised and underdelivered, including, arguably Bitcoin itself and we see that with a dearth of mainstream end user adoption for any of them.  What I’d like to help provide Koinify is the knowledge of the past, to avoid the pitfalls of other projects.  To accomplish this, Melotic is looking to provide liquidity to unique curated assets, potentially those incubated at Koinify.  Thus, this is a mutually beneficial partnership.
  • I have been following the growing list of distributed computing and computational consensus proposals.  Beyond the annual academic Dijkstra Prize, the nascent digital currency space has been fast in proposals but slow in actual production-level roll-outs.  To be frank, I have been fairly disappointed with both the quality of product and traction of 2.0 projects in general, especially given the community euphoria in the first quarter when I did research for Great Chain of Numbers.  However, with that said, if something like Bitcoin is allowed to be given a 5-6 year “grace period” I think it is only fair for a similar runway to be given to other proposals as well.  Furthermore, there are economic trade offs depending on the level of trust and consensus required, but shoving everything onto one ledger, some kind of jack-of-all-trades Houdini ledger, is a bit like the clown car at a circus.  It can be filled with a cornucopia of clowns and coins (and clowncoins) but the economic incentives might not align with the duct tape holding it together. Consequently, the community has evolved and created several new potential methods for untrusted nodes on a public network to arrive at consensus, to the point where consensus-as-a-service is becoming its own commoditized subindustry.  In the future, this will likely be abstracted away and developers will be able to fine tune and granularize the level of centralization and trust they want to expose their users to.  Another big development that I am increasingly paying attention to is the regulatory and compliance arena, which many people seem to want to ignore and handwave away.  It is not going to disappear and structuring your project, company and even ledger in a way that reduces your personal liabilities will be an ongoing concern from now on.  There is no point in being a martyr when there are many other areas to push the envelope on in this expanding space.
  • A few weeks ago I gave a presentation covering a number of factors as to why Bitcoin protocol development has plateaued in the past year and as a result how most of the innovation has effectively been outsourced to the altledger ecosystem.  Here a steady stream of both old and new entrepreneurs and developers are toying with variables that cannot be touched with Bitcoin itself due to its current development cycle.  A friend compared the speed at which this industry moved with dog years and this is particularly true in the altledger space.  As a result, a new ledger can be forked, tweaked and spun up that incorporates the latest ideas in this space.  Most do fail and will likely fail in the future, but that’s the nature of iteration in technology.  The biggest challenges for Koinify is on boarding high quality decentralized apps that bring the utility and value that is now expected by the community.   On the one hand creating a platform that allows access to something like cryptosecurities such as Overstock.com sounds neat, yet it is a hundred year old idea (equity) married to a different type of database (a blockchain). On the other hand, the decentralized app economy that Koinify is attempting to create is in fact has a different form, yet still pragmatic enough given existing technology.  Market participants want to experiment, poke, prod and have choices — this effervescent vitality is attractive and I am excited to try and help out.

Cryptocurrency in the news #29

Turns out about 15 months ago, someone had already figured out how the mining costs of hash-based proof of work moved relative to the market prices of tokens, see “Why Bitcoin will never be a good store of value” by Stefan Loesch.  One common retort to Loesch’s argument is that at some point in the future, for some reason, users will one day start paying higher tx fees.  This is unlikely because it is a collective action problem.  Why would people pay several orders of magnitude more to have the same exact service?

A new feature/dashboard that I came across is CoinGecko — has some interesting metrics to look at.

Explaining trading volumes in China

CoinDesk recently reached out to me to ask and see if I had any views on the divergent Bitcoin trading volumes between China relative to the rest of the world.  The piece they ran included a few of my comments as well as some from several other traders and exchange operators, “China’s Market Dominance Poses Questions About Global Bitcoin Trading Flows.”

Readers may also be interested in a few other comments I provided them, a few of which are slightly edited (removed some names and numbers):

  • I should preface this by saying that the OTC/off-chain liquidity/inventory is something that is not being factored into most of the overall discussion on trade volume.  I know that all the mining farms in China have liquidity partners (usually with the big three exchanges) and I could introduce you to one in particular who might be willing to talk on the record, or at least give you color.  The reason I mention this is because if you can some how dig up the OTC/dark inventory numbers, the aggregate volume might actually be larger in USD than RMB (at least, that would be my guess).
  • To answer your first two questions I think it bears mentioning that there really hasn’t been any new VC-backed exchange that has setup in the US in the past 6 months or so (itBit moved its SG operations to NYC).  Perhaps once the legal issues are more defined this can change.
  • In addition to having no fees on trades, I think this short comment on reddit describes some of the internal structural differences at the Chinese exchanges for question #3.
  • They’re busily trying to answer question #4 with a variety of value-added services like margin trading and issuing of derivative products as well as integrating with API services and even building out support for mining contracts (BTCChina apparently just acquired a mining pool/farm to do just that).
  • As far as your last question, I think it would be fair to say that public/open consumer-based exchanges are centered in China, but based on the OTC numbers that I hear throughout each month, USD is still probably bigger.  For instance, BitPay sells around XXXX BTC a day to its liquidity partners. That’s usually more than ______ does (at least this past summer).  Their daily sales are chopped/sliced up and sold to liquidity partners.  Charlie Shrem briefly touched on this a week or so ago.

Tim, why don’t you send yourself to a provably unspendable address?

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.”

On putting the theft at Mt. Gox into perspective:

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.

On the continual problem surrounding the ‘circular flow of income‘:

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.”

On volatility:

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.”

Cryptocurrency in the news #28

Much like “The Singularity” was en vogue 10 years ago for a slew of reasons that haven’t really materialized (i.e., “an idea before its time”), it is equally unclear how or why blockchains + the Internet of Things has been receiving so much attention. For instance, IBM recently published: “Device democracy: Saving the future of the Internet of Things.”

Let’s be quite clear: yes this technology could develop to work as stated in the next decade.  However, it is unclear why Ethereum, which has still not launched despite 8 months of non-stop marketing, is being cited as the test bed.  I am skeptical that when it does launch, that its economic model will be able to fuel the use-cases that everyone seems to throw at it.

In the meantime, other stories this past week:

The Continued Existence of Altcoins, Appcoins and Commodity coins

False analogies in Bitcoinland plus Alibaba

Saw two analogies used today that are inaccurate.

Writing at Forbes, Eric Mu interviewed Jake Smith, better known as “The Coinsman.”  Jake was responding to a comment I wrote last month:

Tim Swanson, the author of The Anatomy of a Money-like Informational Commodity, recently said that you missed the “unseen calculation, the economics of extracting and securing rents on this ledger unit, which consume scarce resources from the real economy.” – Do you think he is wrong?

I think attacking mining from an environmental point of view is quite silly, because pretty much everything in the modern era relies on resource consumption, and for the vast majority of those things society has decided that the trade-off is worth it. I think Bitcoin is one of the most valuable and revolutionary inventions the world has ever seen, so even if it is using a lot of electricity I don’t think that’s a valid criticism against it. The internet uses vastly more electricity than Bitcoin, no one is bashing the internet for using resources.

Swanson’s quote would also imply that Bitcoin is not part of “the real economy”. I would say that by virtue of its existence, it is.

Further, Bitcoin’s value is derived in part from the fact that it is difficult to create.

The biggest problem with the analogy above, which is commonly used by Bitcoin advocates, is that it is not an apple’s to apple’s comparison.  In this instance, Bitcoin acts as a distributed Excel workbook, a spreadsheet application that uses the internet to distribute itself.  Thus it is incorrect to equate it with the much broader umbrella that is the entirety of the internet.

This same problem happens when people claim that Bitcoin can and/or will replace the banking system.  For instance, last month Jake interviewed Nan Xiaoning, CEO of Bitocean:

I think Satoshi had a lot of foresight in this regard. He wasn’t a dummy, I’m sure he considered different ways of distributing coins.

Some people say that bitcoin wastes a lot of electricity. But the banking industry surely uses more resources than bitcoin does. But bitcoin is a peer-to-peer system. I think using resources to guarantee its security and stability is the way it should be.

Another inaccurate analogue/comparison.  Bitcoin’s protocol does not provide any of the functionality of the banking system beyond a security lock box (that should not be confused with a distinctly different term, a savings account) and a corresponding ledger of access and usage (the debate over whether or not someone “owns” a privkey corresponding to a UTXO it is still being argued over by lawyers globally).  The current protocol does not natively allow for lending, saving, notary, underwriting debt and equity or setting of interest rates (among many other services real banks actually provide).

In both cases above the examples above miss the forest from the trees.  As Robert Sams pointed out a few days ago, the proof of work mechanism used in Bitcoin was designed to make Sybil attacks expensive.  The verification process is a marginally trivial task and can be handled (and in practice actually is handled) by mining pools via small computers such as a Pi-based box.

How specialized is the hashing (not verification) process?  A good comment on reddit yesterday noted that:

Rather than taking the whole header, they mine using something called a midstate. Due to the nonce being at the end of the header, the software hashes up to just before the nonce, and then sends that (called a “midstate”) to the mining chip. The mining chip then only needs to add a nonce, do the end of a SHA256 round, and then one more, and then check if the result is good enough. Rather than returning data, they just return nonces which look to be valid.

Instead, a more accurate way to look at this issue is from the spectrum of centralized to decentralized (which was also discussed by the Hyperledger team in an interview a couple days ago).

Centralized tools and services have certain vulnerabilities (e.g., single point of failure and potential abuse) but its cost basis is different than say, a decentralized entity.  The economics of both need to be accounted for (and are) when rolling out a new system internally (this is called the Total Cost of Ownership).

On the other end, decentralized systems are less vulnerable to some of the same issues that centralized systems are, yet to make them less vulnerable in fact requires consuming scarce resources that centralized solution do not have to (because they are trusted networks).  In the case of Bitcoin, bitcoin miners (or technically hashers) effectively destroy (or “burn”) a corresponding amount of energy (technically exergy) to protect the network from Sybil attacks on an untrusted network.  This is a real cost that cannot be ignored yet as shown above, is often handwaved away.

[Note: as an aside, most miners, mining farms and mining manufactures do not pay for their capex or opex in bitcoins, nor is this likely going to change anytime soon.  Instead they must rely on and permaborrow the unit of account of fiat (typically a USD or RMB) to effectively measure and allocate resources.  This unit of account issue -- wherein economic activity within the Bitcoin world is measured with the unit of account that is fiat to create this network -- was also broached by Robert Sams several months ago.]

Furthermore, as I mentioned in chapter 8, if the TCP/IP analogy was correct then the marginal revenue for ISPs would split in half every 4 years.  And that through competition the marginal cost of protecting and sending packets would equal the marginal value of those packets.  This would not be an effective way to run a business let alone design a network topology.

In the real world, the marginal costs of running an ISP, which is centralized, have to be less than the marginal revenue otherwise they go bankrupt as they could not pay for overhead.  So yes, in fact, ISPs do try to actually mitigate the leakage, wastes and otherwise inefficiencies in its own internal network and they do this through a myriad of ways.

Bitcoin’s existence is on the other side of the spectrum.  Bitcoin was purposefully designed to make it cost prohibitive to spam ownership change on a public, untrusted network — the complete opposite in organization that an ISP is designed to operate as.  The average person would likely see this as inefficient, but that is because up until the past decade — with the advent of Bittorrent and other distributed systems — the public at large was unfamiliar with how these systems are designed.  And as Sams pointed out, using the word “efficient” versus “inefficient” may not be the most accurate terminology, because each model has different attack vectors they have to account for.

Thus again, it is not about being pro or anti proof-of-work.  Rather it is acknowledging that proof of work requires a certain economic model that have real costs that scale with token value and in the case of Bitcoin, is not environmentally “greener” than some centralized solutions (e.g., ApplePay).

The case of Alibaba

Over the past couple of days some Bitcoiners have recently claimed that the recent dip in market prices for bitcoins is because of the Alibaba IPO; “Alibaba’s US IPO May Have Crashed the Bitcoin Price.”

Not only does this show that several vocal Bitcoiners are unfamiliar with how real IPOs work (underwriters typically represent the lion’s share of additional equity ownership and the date is fixed weeks and months ahead of time) but that it illustrates how some Bitcoiners like to blame people and go on a witch hunt when prices decline but then reassure themselves that they are investment geniuses when prices trend northerly.

In point of fact, the Alibaba IPO was not a surprise to anyone, the investors are all large financial institutions and not hoi polloi.  The IPO was oversubscribed and not even well heeled, well connected HNWIs could get into an allotment — only banking institutions were able to because of the enormous demand.  And none of those institutions are: 1) large bitcoin holders and 2) needed to sell bitcoins to raise funds to buy Alibaba shares.

Perhaps this will change in the future, but that is not the case in this instance (be sure to also check out Izabella Kaminska’s lively twitter feed).

Why do prices fluctuate #2?

Yesterday CoinDesk asked for my take on the current downtrend in market prices.  Incidentally, nearly a month ago, this same question was sent to me (here was my response then).  I sent them a statement and they published a couple of the comments in a new article, “Downward Pressures Persist as Bitcoin’s Price Declines to Near $400.”

Readers may be interested in a few of the other comments I mentioned to CD below:

Charlie Shrem made some interesting comments about OTC liquidity earlier today.  However, the fact that merchants and some miners are not dealing with exchanges directly, does not mean they cannot move the price.  That is what we are seeing now — it may not matter how many people are “buying off-chain” or “off-market” because no one wants to lose money.

And in other cases, an OTC buyer can affect exchange via “buy pressure.”  If he begins buying directly from an OTC provider, avoiding an exchange, the exchange loses its buy wall thus affecting price.  The sell pressure forces the price down and once a large buyer goes “off-market,” he is weakening the buy pressure.  If all the buyers and sellers are “off-market,” we can say that exchange price and price discovery is distorted.  As my friend Raffael Danielli recently said, “Information is never off-chain and ultimately information makes the price.”  Consequently today information spreads very quickly and if a broker can make money because he facilitates “off-chain” transaction and knows “better” what the real price is then game theory dictates he should take advantage off this (investment banks do the same with OTC).

So in addition to partnership agreements, they probably also sell somewhere else to mitigate exposure to this volatility.  In addition, many miners have to finance their operations and at current prices of $410, roughly $1.6 million is created every day via block rewards and it has to go somewhere.  Fewer people buying?  Down we go.

People are always rationalizing things in a down turn.  Maybe an early adopter bought a house or car and cashed out a couple of million worth the past couple of days.  Or maybe some of the dev teams that recently raised funds via crowdsales need to sell in order to fund development.  Just because the ticker price says $410 doesn’t mean every bitcoin in the world is worth $410.  It is temporal and the public market is still very illiquid, so start cashing out and see what happens to market prices.  Again, it is only as valuable as another party is willing to pay for it.  And in theory, it will only stop once the marginal cost of creating new coins equals the current price (MV=MC), which Robert Sams wrote about earlier this week..  Though in practice, some miners can operate at loss to recover at least some funds — however it would be in their best interest to simply turn off their equipment instead and buy bitcoins with the expectation of price appreciation.  It also depends on how much they’re leveraged at places like Paymium, BTCJam and Bitfinex.

Does Smart Contracts == Trustless Multiparty Monetary Computation?

My friend, Zaki Manian, who is working on a very interesting project called SKUChain (discussed in chapter 16), thinks we should reframe how we perceive or rather how we should define ‘smart contracts.’

In his view:

Here is my proposal.

We stop calling the idea ” smart contracts” and we start calling the idea “Trustless Multiparty Monetary Computation”. That should also tell the lawyers that we don’t really need them here at the moment….

Programming Language researchers use the term “contracts” as a way of formally reasoning about multi-part or distributed computation. But PL researchers also understand that this is idea has deep formal connections with reasoning about the relationship between people and organizations.

Here is the relevant prior art.

Got an email asking me more about the War of Spanish Succession related to gold.  My point on that panel wasn’t so much that France only used gold, but their finances were directly tied to specie (technically the French livre was in two forms: silver écu and gold Louis d’or; see also Livre tournois).  The reason I brought it up at all is because of the meme today, that Bitcoin would somehow prevent war because it neutralizes the states ability to expand its money supply, etc..  It won’t though.  Probably a better historical example are European countries from mid-19th century which adopted some form of a gold standard, yet then went on to wage a global war eventually dropping the peg altogether.  Be sure to read a new article from The Economist that discusses this, “Not floating, but flailing.”

Thanks to Izabella Kaminska (follow her on Twitter) and Zaki Manian for a couple links.

Also, be sure to check out Izabella’s thread today on Coinbase.  Based on a conversation with one lawyer I had two weeks ago it looks like a big legal challenge for Coinbase (and others in their vertical) is that they’re acting as depository institutions without having gone through the necessary “Safety & Soundness” tests which opens them up to legal action from a variety of state/federal agencies.

A panel on smart contracts with industry developers and educators

Earlier today I participated in a virtual panel covering smart contracts called, “Let’s Talk Smart Contracts.”

The panel included: Adam Krellenstein (Counterparty), Oleg Andreev (CoreBitcoin), Pamela Morgan (Empowered Law), Stefan Thomas (Codius, Ripple Labs), Stephan Tual (Ethereum), Tim Swanson (Of Numbers), Yurii Rashkovskii (Trustatom) and it was moderated by Roman Snitko with Straight.

Below are some transcribed notes of my own statements.

Introduction starting at 09:06:

Hey guys, great to be here.  Thanks for the invite, thanks for organizing this.  So I’m here because you guys needed another white guy from Europe or something like that (that’s a joke).  So the definition I have of smart contracts, I have written a couple books in this space, and the definition I use is a smart contract is “a proposed tool to automate human interactions: it is a computer protocol – an algorithm – that can self-execute, self-enforce, self-verify, and self-constrain the performance of a contract.”  I think I got most of that definition from Nick Szabo’s work.  For those of you who are familiar with him, look up some of his past writings.  I think that the primary work he is known for is the paper, “Formalizing and Securing Relationships on Public Networks.”  And he is basically considered the [intellectual] grandfather of this space.  I’m here basically to provide education and maybe some trolling.

From 22:02 -> 24:15

I think I see eye-to-eye with Adam here.  Basically the idea of how we have a system that is open to interpretation, you do have reversibility, you do have nebulousness.   These are things that Nick Szabo actually discussed in an article of his called “Wet code and dry” back in 2008.  If you look back at some of the earlier works of these “cypherpunks” back in the ’90s, they talked about some of these core issues that Oleg talked about in terms of being able to mitigate these trusted parties.  In fact, if you look at the Bitcoin whitepaper alone, the first section has the word “reverse” or “reversibility” around 5 times and the word “trust” or “trusted” appears 11 times in the body of the work.  This was something that whoever created Bitcoin was really interested in trying to mitigate the need for any kind of centralized or third party involved in the process of transactions to reduce the mediation costs and so forth.

But I suppose my biggest criticism in this space, it is not pointed to anyone here in particular, is how we have a lot of “cryptocurrency cosplay.”  Like Mary Sue Bitcoin.  I’m not sure if you guys are familiar with who Mary Sue is: she is this archetype who is this kind of idealized type of super hero in a sense.  So what happens with Bitcoin and smart contracts is that you have this “Golden Age” [of Comics] where you had the limited ideas of what it could do.  Like Superman for example, when he first came out he could only jump over a building and later he was pushed to be able to fly because it looks better in a cartoon.  You have only a limited amount of space [time] and it takes too long to jump across the map.  So that’s kind of what I see with Bitcoin and smart contracts.  We can talk about that a little bit later, just how they have evolved to encompass these attributes that they’re probably not particularly good at.  Not because of lack of trying but just because of the mechanisms of how they work in terms of incentives for running mining equipment and so on.  So, again we can talk about that later but I think Adam and Oleg have already mentioned the things that are pretty important at this point.

40:18 -> 41:43

I’m the token cynic, huh?  So actually before I say anything, I would like to mention to the audience other projects that you might be interested in looking at: BitHalo; NotaryChains is a new project that encompasses some of these ideas of Proof of Existence created by Manuel Araoz, he is the one who did POE.  NotaryChains is a new project I think that sits on top of Mastercoin.  The issue that people should consider is that proof of existence/proof of signature: these are just really hi-tech forms of certification.  Whether or not they’re smart contracts I guess is a matter of debate.

There is another project: Pebble, Hyperledger, Tezos, Tendermint, Nimblecoin.  With Dogethereum their project is called Eris which apparently is the first DAO ever.  A DAO for the audience is a decentralized autonomous organization, it’s a thing apparently. SKUChain is a start-up in Palo Alto, I talk about them in chapter 16.  They have this interesting idea of what they call a PurchaseChain which is a real use-case for kind of updating the process from getting a Letter of Credit to a Bill of Lading and trying to cut out time and mediation costs in that process.  There are a few others in stealth mode.  So I really don’t have a whole lot to add with cynicism at this point, we can go on and come back to me in a little bit.

59:41 -> 1:02:35

The go to deficiency guy, huh?  They’re not really saying anything particularly controversial, these things are fundamentally — at least from an engineering perspective — could be done.  The problem though I think runs into is what Richard Boase discussed in — if listeners are interested — he went to Kenya and he did a podcast a few weeks ago on Let’s Talk Bitcoin #133.  I really recommend people listen to it.  In it he basically talks about all of these real world issues that run into this idealized system that the developers are building.  And as a result, he ended up seeing all of these adoption hurdles, whether it was education or for example tablets: people were taking these tablets with bitcoin, and they could just simply resell it on a market, the tablet itself was worth more than they make in a year basically; significant more money.  He talked about a few issues like P2P giving, lending and charity and how that doesn’t probably work like we think it does.

I guess the biggest issue that is facing this space, if you want issues, is just the cost benefit analysis of running these systems.  There is a cost somewhere to run this stuff on many different servers, there is different ways to come up with consensus for this: for example, Ripple, Stellar, Hyperledger, they’re all using consensus ledgers which require a lot less capital expenditures.  But when you end up building something that requires some kind of mining process itself, that costs money.  So I think fundamentally in the long-run it won’t be so much what it can do but what can it economically do.

So when you hear this mantra of let’s decentralize everything, sure that’s fine and dandy but that’s kind of like Solutionism: a solution looking for a problem.  Let’s decentralize my hair — proof of follicle — there is a certain reductio ad absurdum which you come to with this decentralization.  Do you want to actually make something that people are actually going to use in a way that is cheaper than an existing system or we just going to make it and throw it out there and think they’re going to use it because we designed [wanted] it that way.  So I think education is going to be an issue and there are some people doing that right now: Primavera De Fiillipi, she’s over at Harvard’s Berkman Center — she’s got something called the Common Accord program.  And also Mike Hearn; listeners if you’re interested he’s made about 7 or 8 use-cases using the existing Bitcoin blockchain including assurance contracts — not insurance contracts — assurance contracts.  And he’s got a program called Lighthouse which hopes to build this onto the actual chain itself.  So there are things to keep in mind, I’m sure I’ll get yelled at in a minute here.

1:23:58 -> 1:28:10

Anyone listening to this wanting to get involved with smart contracts: hire a lawyer, that’s my immediate advice.  I will preface by saying I don’t necessarily agree with policies that exist and so on; I don’t personally like the status quo but there is no reason to be a martyr for some crusade led by guys in IRC, in their little caves and stuff like that.  That’s not towards anyone here in this particular chat but you see this a lot with “we’re going to destroy The Fed” or “destroy the state” and the reality is that’s probably not going to happen.  But not because of lack of trying but because that’s not how reality works.

Cases right now are for example: DPR, Shavers with the SEC, Shrem now with the federal government, Karpeles [Mt. Gox] went bankrupt.  What’s ended up happening is in 2009, with Bitcoin for example, you started with a system that obviated the need of having trusted third parties but as users started adopting it you ended up having scams, stolen coins, people losing coins so you ended up having an organic growth of people wanting to have insurance or some way to mediate these transactions or some way to make these things more efficient.  And I think that it will probably happen — since we’re guessing, this is speculative — I think that this will kind of happen with smart contracts too.  That’s not to say smart contracts will fail or anything like that.  I’m just saying that there will probably just be a few niche cases initially especially since we don’t have much today, aside I guess from Bitcoin — if you want to call it a smart contract.

What has ironically happened, is that we have created — in order to get rid of the middlemen it looks like you’ve got to reintroduce middlemen.  I’m not saying it will always be the case.  In empirical counter-factual it looks like that’s where things are heading and again obviously not everyone will agree with me on that and they’ll call me a shill and so on.  But that’s kind of where I see things heading.

I have a whole chapter in a book, chapter 17.  I interviewed 4 or 5 lawyers including Pamela [Morgan] of different reasons why this could take place.  For example, accredited investor — for those who are unfamiliar just look up ‘accredited investor.’  If you’re in the US, in order to buy certain securities that are public, you need to have gone through certain procedure to be considered a ‘sophisticated investor.’  This is one of the reasons why people do crowdsales outside of the US — Ethereum — because you don’t want to have to interact with the current legal system in the US.  The reason I mention that is because you end up opening yourselves to lawsuit because chains — like SWARM — cannot necessarily indemnify users.  That’s legal terminology for being able to protect your users from lawsuits from third parties; they just do not have the money, the revenue to support that kind of legal defense.  Unlicensed practice of law (UPL) is another issue.  If you end up putting up contracts on a network one of the issues could be, at least in the US, are bar associations.  Bar associations want to protect their monopoly so they go after people who practice law without a license.  I’m not saying it will happen but it could happen.

My point with this is, users, anyone listening to this should definitely do your due diligence, do your education.  If you plan to get involved with this space either as an investor or developer or so on, definitely at least talk to a lawyer that has some inkling of of an idea [on this].  The ones I recommend, in addition to Pamela here are: Ryan Straus, he is a Seattle-based attorney with Riddell Williams; Austin Brister and James Duchenne they’re with a program called Satoshi Legal; and then Preston Byrne, who’s out in London and he’s with Norton Rose Fulbright.

1:52:20 -> 1:54:43

Guys look, I understand that sounds cool in theory and it’s great to have everything in the background, but the reason you have to see these “shrink wrapped” EULAs [end user license agreements] and TOSs [terms of service] is because people were hiding stuff inside those agreements.  So if you hide what’s actually taking place in the contract you end up making someone liable for something they might not actually agree to.  So I’m not sure, I think it’s completely debatable at this point.  If we’re trying to be transparent, then you’re going to have to be transparent with the terms of agreement.

I should point out by the way, check out Mintchalk.com, it’s run by guys named James and Aaron in Palo Alto, they’re doing contract building.  ACTUS is a program from the Stevens Institute, they’re trying to come with codified language for contracts.  Mark S. Miller, he’s got a program over at Google, he does something with e-rights.

I mention all of this because, we already have a form of “polycentric law” if you will in terms of internationally with 200 different jurisdictions vying for basically jurisdiction arbitrage.  Ireland and the Netherlands have a tax agreement that Facebook, Google, Pfizer they take advantage of.  It’s this Double Irish With a Dutch Sandwich.  In fact my own corporation is incorporated in Delaware because of the legal arbitrage [opportunities].  Obviously smart contracts might add some sort of new wrinkle to that, but people who are listening to this, don’t expect to be living in some Galt’s Gulch tomorrow or something like that.

For example, when you have something that is stolen, there is something called Coinprism which is a colored coin project.  They can issue dividends on stock.  The cool thing with that is, “hey, you get to decentralize that.”  The double-edged side of that is if that when that get’s stolen: people steal stuff like bitcoins and so forth, what happens to the performance of that dividend?  If the company continues paying that dividend in knowing that the person had been stolen from: if somebody stole from me and I tell the company, “hey, it was stolen” and they continue paying, then I can sue them for continuing to pay a thief.  If they stop paying then it defeats the purpose of decentralization because anonymity is given up, identity has taken place.  Obviously this moves into another area called “nemo dat” it’s another legal term talking about what can be returned to the rightful owner, that’s where the term “bona fide” comes from.  Anyways, I wanted to get that out there.  Be wary of disappearing EULAs, those have a purpose because people were being sued for hiding stuff in there.

2:10:05 -> 2:12:23

So I think everybody and all these projects are well-intentioned and have noble goals but they’re probably over-hyped in the short-run, just like the Segway was.  It eventually leads to some kind of burnout, or over-promise and under-delivering.  I’m not saying this will happen, I’m just saying it could happen.  I actually think the immediate future will be relatively mundane, such as wills and trusts kind of like Pamela was talking about.

One particular program is in Kenya there is something called Wagenitech which is run by Robin Nyaosi and he is wanting to help farmers move, manage and track produce to market to bypass the middleman.  That doesn’t seem like something really “sexy,” that doesn’t seem like the “Singularity” kind of thing that everyone likes to talk about.  But that is needed for maybe that particular area and I think we might see more of that along with PurchaseChain, NotaryChains, some of these things that we already do with a lot of the paperwork.

Again, blockchains and distributed ledgers are pretty good at certain things, but not everything.  It has real limitations that vocal adopters on the subreddit of Bitcoin like to project their own philosophical views onto it and I think that it does it a very big disservice to this technology long-term.  For example, LEGO’s can be used to make a car but you wouldn’t want to go driving around in one.  A laptop could be used as a paper weight but it’s not particularly cost effective to do that.  And so what I think we’ll end up running into a tautology with smart contracts, it’s going to be used by people who need to use them.  Just like bitcoin is.  So what we’re going to have is a divergence between what can happen, this “Superman” version of Bitcoin and smart contracts, versus the actual reality.

So for example, people say it’s [Bitcoin] going to end war.  You had the War of Spanish Succession, there was a Battle of Denain, a quarter million people fought that in 1712 and it was gold-based [financed by specie].  Everyone that says bitcoin is going to destroy fiat, if the state exists as it does today there’s always going to be these institutions and types of aggression.  I do think smart contracts do add collateral and arbitration competition and it does take away the problem of having trust in the system itself, but the edges are the kryptonite.  And always will be.  So we need to focus on education and creating solutions to real actual problems today with the actual technology and not just some hypothetical “Type 2″ civilization where we are using [harvesting] the Sun for all of our energy.

Cryptocurrency in the news #23

Closing tabs.

A few interesting stories, the first of which is from The Economist, “The dollar’s sterling work.”  One notable passage from the article is, “people exaggerate the importance of the yuan. Just $0.3 trillion of Chinese assets are open to foreign investors, compared to $56 trillion of American ones. That makes the yuan a poor candidate for a global reserve currency.”

As I explored in chapter 13, Bitcoin adopters who continue to claim bitcoin will become a reserve currency usually do not understand how or what foreign currency reserves are.  The Chinese RMB, not bitcoins, has a more probable future as a reserve currency and as discussed by The Economist and others cited in chapter 13 (such as Patrick Chovanec), this is not going to happen anytime soon for the RMB, if ever.

I also recommend reading through “Inside Visa’s Data Center” published last year to give you an idea of the quality and security of their network.  Significantly different (42 firewalls, mirrored center in Midwest) than the cartoon caricature that some vocal “decentralize the worlders” claim it as.

Thanks to Izabella Kaminska and others for a couple of the links.
