I'm amazed at Mastering Ethereum's breadth, scope, and accessibility... I highly recommend it for your shelf.

Mastering Bitcoin is the canonical reference that made Bitcoin and blockchain technology accessible to a broad audience, and Mastering Ethereum does the same for the Ethereum world computer.

Mastering Ethereum is a fantastically thorough guide, from basics to state of the art practices in smart contract programming, by two of the most eloquent blockchain educators.

Mastering Ethereum will become a must read in the future, as Ethereum is going to be as ubiquitous as TCP/IP. It will become a necessary layer under which decentralized, trustless technologies live and thrive.

Hudson JamesonCommunity Organizer - Ethereum Foundation

Mastering Ethereum is the perfect book for anyone who wants to learn more about Ethereum, whether you're looking to test the waters or dive straight into the deep end. Between Gavin Wood's technical knowledge of Ethereum's inner workings and Andreas M. Antonopoulos' ability to make complex subjects approachable, you get the best of both worlds with this book. I only wish it had been around when I first started diving into Ethereum.
