Passes muster as an intro book, but not much beyond the first couple of chapters for those who have been in the space for a few years.
The intro chapter was the best part as it provided a concise history of digital currency initiatives that led to Satoshi's world-changing protocol in 2008-09.
David Chaum introduced eCash in the 80s, followed by Adam Back's HashCash in 1997, Wei Dai's b-money in 1998, and Nick Szabo's bit gold in the same year. Each was flawed in its own way - overly centralized, no Proof of Work node, no difficulty adjustment, etc. But it was only through these discarded attempts that Satoshi could find footing atop the shoulders of giants to see further than they had a decade or more earlier.
Boyapati gives a solid rundown of what qualities something needs to be considered money, with history the only piece bitcoin really lacks now, and with gold still ahead of fiat on all but portability and divisibility. (Bitcoin wins, but gold still outperforms fiat. An uncensorable 24/7 digitial protocol hard-capped at 21 million coins and running on thousands of nodes all over the world will outperform a shiny rock, but that shiny rock that is relatively scarce, nearly indestructible, and with 5,000 years of history will fare better than a piece of paper some bureaucrat can create more of by pressing a button)
We get a look at adoption timelines (bitcoin is playing out much like cell phones and the Internet) as well as how money transitions from a collectible to store of value to unit of account to medium of exchange. The book closes with some FUD-busting (centralization, nation state attacks, broken protocol, competitors) and that's it. Not a bad 90 minute read but not enough new material to give it 4 stars.
