My book
Why I Wrote Blockchain by Example in 2016
When I started writing Blockchain by Example in 2017, blockchain was gaining momentum, but practical learning resources were scarce. Most books and articles focused on the theory behind blockchain, leaving developers with few comprehensive guides to build real applications.My goal was to create the book I wished had existed when I started learning blockchain: a hands-on guide that takes readers from the fundamentals to complete, working projects.The book begins by explaining how Bitcoin works and even shows how to build your own forked cryptocurrency. From there, it explores Ethereum and smart contracts before diving into enterprise blockchain with Hyperledger Fabric, where readers build end-to-end business applications.Although the blockchain ecosystem has evolved considerably since the book was published, the core concepts, architectures, and development principles remain relevant. I hope this book continues to help developers understand not only what blockchain is, but how to build with it.
