About 10 days ago I had the pleasure of speaking at Blockchain University (hosted over at PwC) regarding distributed ledgers (permissioned and permissionless).  One of the slides was intentionally taken out of context by a user on reddit and unsurprisingly the subsequent /r/bitcoin thread covering it involved a range of ad hominem attacks that really missed what was being discussed at the actual talk: what are the characteristics of a blockchain.

I will likely write a post on this topic at length in the next couple of days.  In the meantime, below is the video which incidentally pre-emptively answered a few of the questions from that thread.

Also, for those curious to know who were asking the good questions in the audience, this included: Jeremy Drane (PwC), Christopher Allen (co-creator of the TLS standard) and Nick Tomaino (Coinbase) among others.
