Interesting to see the footnote at the end about enterprise/consortium blockchain systems. I designed one of the more popular one of those. If you've got questions Paul feel free to email me. Naturally I'm very biased, but I wouldn't say they were all developed merely so companies could have a blockchain strategy. Certainly just keeping up with the Joneses was a motivation for some of the middle/upper executives who sponsored some of the apps built on those platforms, just like it is for AI now, and was for XML back in the day. But there were also actual real business problems worked out in detail, with people who genuinely wanted to solve them and saw a chance to use blockchain hype as a Schelling point to coordinate large numbers of companies to collaborate better. And real apps have been developed and shipped on these, that provide at business value. It'd probably be interesting to write about some of these systems from a purely technical perspective, as a decentralised database engine, because the underlying protocols and designs are pretty interesting and (at least in Corda's case) quite powerful too.
