Welcome to Blockchain For Dummies! If you want to find out what blockchains are and the basics of how to use them, this is the book for you. Many people think blockchains are difficult to understand. They might also think that blockchains are just about cryptocurrencies like Bitcoin, but they’re are so much more. Anyone can master the basics of blockchains.
In this book, you find helpful advice for navigating the blockchain world and cryptocurrencies that run them. You also find practical step-by-step tutorials that will build your understanding of how blockchains work and where they add value. You don’t need a background in programming, economics, or world affairs to understand this book, but I do touch on all these subjects because blockchain technology intersects all of them.
