At 2 years old, this is already feeling dated, but it gives a detailed look at the start of the blockchain 'revolution' in progress. The authors' backgrounds in finance/economy give them a particular slant but it doesn't keep them from diving into the cultural and technological effects of blockchain technology. As expected, there are some interesting guesstimates as to where the new tech might take us, but given what blockchain can already do out of the box, so to speak, is pretty impressive.
Required reading for a baseline in blockchain, but you'll want to add some newer sources to your reading stack, probably including some blogs/news feeds to keep up. This tech is so new the changes are coming quick and heavy.
