Blockchain 101
It is very likely that if you are reading this book, 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, the IT, finance, government, media, medical, and law sectors, by making them more efficient, trustworthy, and transparent.
This chapter introduces blockchain technology, its technical foundations, the theory behind it, and various technologies that have contributed to building what is known today as blockchain. The theoretical foundations of distributed systems are described first. Next, the precursors of Bitcoin are presented. Finally, blockchain technology is introduced. This approach is a logical way of understanding blockchain technology, as the roots of blockchain are in distributed systems and cryptography. We will be covering 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 throughout the book.
In this chapter, we’ll focus on:
- The growth of blockchain technology
- Distributed systems
- The history of blockchain
- Introducing blockchain
- Types of blockchain
