A blockchain is a distributed ledger that is replicated across multiple nodes and enables immutable, transparent and cryptographically secure record-keeping of transactions. The blockchain technology is the backbone of cryptocurrencies, and it has applications in finance, government, media and almost all other industries. Mastering Blockchain, Second Edition has been thoroughly updated and revised to provide a detailed description of this leading technology and its implementation in the real world. This book begins with the technical foundations of blockchain technology, teaching you the fundamentals of distributed systems, cryptography and how it keeps data secure. You will learn about the mechanisms behind cryptocurrencies and how to develop applications using Ethereum, a decentralized virtual machine. You will also explore different other blockchain solutions and get an introduction to business blockchain frameworks under Hyperledger, a collaborative effort for the advancement of blockchain technologies hosted by the Linux Foundation. You will also be shown how to implement blockchain solutions beyond currencies, Internet of Things with blockchain, blockchain scalability, and the future scope of this fascinating and powerful technology.

Blockchain 101

If you are reading this book, it is very likely that you already have heard about blockchain and have some fundamental appreciation of its enormous potential. If not, then let me tell you that this is a technology that has promised to positively alter the existing paradigms of nearly all industries including, but not limited to IT, finance, government, media, medical, and law.

This chapter serves an introduction to blockchain technology, its technical foundations, the theory behind it, and various techniques that have been combined together to build what is known today as blockchain.

In this chapter, we first describe the theoretical foundations of distributed systems. Next, we address the precursors of Bitcoin by which blockchain technology was introduced to the world. Finally, we introduce you to blockchain technology. This approach is a logical way to understanding blockchain technology, as the roots of blockchain are in distributed systems. We will cover a lot of ground quickly here, but don't worry—we will go over a great deal of this material in much greater detail as you move through the book.
