Foundations of Blockchain

By: Koshik Raj

Overview of this book

Blockchain technology is a combination of three popular concepts: cryptography, peer-to-peer networking, and game theory. This book is for anyone who wants to dive into blockchain from first principles and learn how decentralized applications and cryptocurrencies really work. This book begins with an overview of blockchain technology, including key definitions, its purposes and characteristics, so you can assess the full potential of blockchain. All essential aspects of cryptography are then presented, as the backbone of blockchain. For readers who want to study the underlying algorithms of blockchain, you’ll see Python implementations throughout. You’ll then learn how blockchain architecture can create decentralized applications. You’ll see how blockchain achieves decentralization through peer-to-peer networking, and how a simple blockchain can be built in a P2P network. You’ll learn how these elements can implement a cryptocurrency such as Bitcoin, and the wider applications of blockchain work through smart contracts. Blockchain optimization techniques, and blockchain security strategies are then presented. To complete this foundation, we consider blockchain applications in the financial and non-financial sectors, and also analyze the future of blockchain. A study of blockchain use cases includes supply chains, payment systems, crowdfunding, and DAOs, which rounds out your foundation in blockchain technology.

Financial blockchain projects

In this section, our goal is to explore a few of the early financial implementations of blockchain in the financial domain by categorizing them.

Cryptocurrencies

The concept of blockchain has evolved since it was first introduced in Bitcoin. Although Bitcoin's underlying technology has been applied in several different fields, cryptocurrency has been recognized as the true application of the blockchain technology. Many projects have since been created, some imitating Bitcoin's implementation and others solving issues in the existing implementation.

Although many cryptocurrencies can be found that possess similar properties to Bitcoin, they don't necessarily solve the same problems...
