The mathematical foundations of blockchains and cryptocurrencies are rooted in an area of Mathematics called cryptography (or cryptology). In this chapter and the three chapters that follow, we will examine these mathematical foundations. Even though I am not going to present the mathematical theory in a rigorous lemma-theorem-corollary style, I am going to present the theory in a lucid and understandable manner. The goal is to provide you with a clear understanding of the underlying mathematical concepts and theory. This deep exposure will be more than sufficient ...
