I finished this book the same evening it arrived. The high-level overview was just what I was looking for. While a web search of the topic would have eventually yielded the same information, this book was better organized and more comprehensive. The print edition had some weird formatting errors and typos, but nothing so bad as to detract from its usefulness. I’m ready to dive into a more meaty book now, but I’m glad I got something that could teach me the basics quickly. I can speak with confidence about mining, hashing and proof of work/stake; I know some basic history of the technology; and I see the potential and challenges of blockchain as it applies to currencies and other applications. Not bad for a couple of hours of reading!

About the author
You get what you pay for
In the Amazon description of the book, you will see about 15 high level blockchain related questions. This book feels like the author Googled each of these questions and just copied and pasted content from the first link. This book is riddled with typos and lacks basic formatting and typesetting which makes the whole book feel like someone threw it together in an afternoon on Microsoft Word. Given this author has published about a dozen books in the last 2 years while working a fulltime tech job, that's very likely what happened here.Instead of buying this book, I would recommend just googling all of the questions listed in the Amazon description as you will get the same information without all the typos. If you actually want a book which ties together all the different concepts of blockchain and cryptocurrencies together, I'd recommend checking out a book called Blockchain Bubble or Revolution instead of this one.What I liked about Bubble or Revolution is that given it just came it a few months ago, it is hyper current and relevant and covers things like Facebook's Libra project, what Walmart is doing with blockchain, etc. Given Blockchain Technology Explained came out in 2017, it definitely feels stale and incomplete at this point. I also felt like Bubble or Revolution did a great job explaining both the how and the why questions of blockchain while Blockchain Technology purely focused on the how.To sum up, if you want the most cost effective option for learning about blockchain, just google the questions listed in this book's Amazon description. If you want to learn by reading a book, pay a couple bucks more and buy Blockchain Bubble or Revolution to get a more thorough and up to date synopsis of how blockchain technology works and where it's going.
