| About |
Learn Blockchain Programming with JavaScript begins by giving you a clear understanding of what a blockchain technology is. You’ll then set up an environment to build your very own blockchain and learn to 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 will 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 network functions and why decentralization is such an important feature for securing a blockchain. |
