Learn Blockchain Programming with JavaScript

By: Eric Traub

Overview of this book

Learn Blockchain Programming with JavaScript begins by giving you a clear understanding of what blockchain technology is. You’ll then set up an environment to build your very own blockchain and you’ll add various functionalities to it. By adding functionalities to your blockchain such as the ability to mine new blocks, create transactions, and secure your blockchain through a proof-of-work you’ll gain an in-depth understanding of how blockchain technology functions. As you make your way through the chapters, you’ll learn how to build an API server to interact with your blockchain and how to host your blockchain on a decentralized network. You’ll also build a consensus algorithm and use it to verify data and keep the entire blockchain network synchronized. In the concluding chapters, you’ll finish building your blockchain prototype and gain a thorough understanding of why blockchain technology is so secure and valuable. By the end of this book, you'll understand how decentralized blockchain networks function and why decentralization is such an important feature for securing a blockchain.

A quick review

With the completion of the previous chapter, we are done building our blockchain. If you think about how much you have accomplished throughout the entirety of this book, it's pretty impressive.

We started with nothing, and from there, we built a blockchain data structure, followed by an API to interact with it. We then turned our API into a decentralized blockchain network, and synchronized the data across the entire network running on multiple different nodes.

We then created a consensus algorithm to make sure that the data on all of our nodes was synchronized and legitimate. Finally, we built a block explorer to explore our blockchain through a user interface. Throughout this entire book, we have built a lot of functionalities, as well as an awesome blockchain prototype.

One important thing that you must be aware of is that, throughout this book, we have...
