I got this book recently to use it as a guide for our Blockchain development. I can say it is encyclopedia covering all the major areas of Blockchain. In short Types of blockchain, Decentralization, Smart Contracts, Crytopgraphy & Security. Applications, Bitcoin & Alt coins. A detailed content on Ethereum & its development. Information on notable coins & projects trending in the market ( not changing trends). Resourceful book for all types of Blockchain enthusiasts.
This book is really a Blockchain Bible. It not only covers the Blockchain but, in the initial parts, it provides an in-depth conceptual understanding of the Bitcoin and underlying crypto maths that drives this technology. Some readers who might want to focus on Blockchain and its use cases will be a bit disappointed with the extensive coverage of Bitcoin and Altcoins. I feel that this coverage could have been kept a bit more concise. But given the fact that this is a very new technology, the author has tried to do justice to all facets of it and that's why I say, it is actually a Bible. Also, the cryptocurrency community around Bitcoin and Altcoin is very volatile and opinionated so everything that the Author has said about the cryptocurrency might be subjected to criticism. But the blockchain coverage is very good and I would recommend this book to anyone who wants to complete low down about the technology as well as the underlying fundamental concepts that drive it.
