This is a self-published book and looks it, with strange spacing, sometimes odd grammar, poor copy editing, and a rather wooden style. So why in the world would I rate it so highly? Well, because it is, in fact, precisely what it says it is. This is a no-frills explanation of what blockchain technology is all about and how it relates to many topics, cryptocurrency, to be sure, but also the many other uses to which this fascinating technology can put. I am a rank amateur (and if you asked me to tell you the actual coding behind blockchain, I wouldn't even know where to begin). But the theory fascinates me and I admire many of the non-currency applications. Journalism in particular could benefit from both the decentralized authority implied by blockchain and the ability to have verifiable, uncensorable stories where they cannot be touched.
I found some of Norman's enthusiasm for the potential of blockchain to be a bit naive, however. I understand how voting, for instance, could someday be made more verifiable through this technology, but the idea that entrenched powers are suddenly going to be overthrown and the voting process ceded to technocrats and miners is a bit far-fetched. At one point he writes, "True popular democracy would permanently change the way government functions, giving control of laws and policies to the population". Well, yes, perhaps, but blockchain cannot magically bring this about. The world is a bit more complicated than that.
I also find questionable his enthusiasm for increased productivity and less need for government magically coming to pass through the use of blockchain. I find it particularly amusing that these technological freedom fighters are one of the major consumers of electricity in the world, a utility the infrastructure of which is paid for and maintained largely through tax dollars.
Still, the muddy philosophical musings aside, when Norman sticks to the facts of what this technology does and how it goes about it, it is fascinating, clear, and understandable. No small feat with something this complex and multifaceted. Well worth a read, if you go in for this sort of thing.
