Explore the essentials of blockchain technology with JavaScript to develop highly secure bitcoin-like applications
Key Features
- Develop bitcoin and blockchain-based cryptocurrencies using JavaScript
- Create secure and high-performant blockchain networks
- Build custom APIs and decentralized networks to host blockchain applications
Book Description
Learn Blockchain Programming with JavaScript begins by giving you a clear understanding of what a blockchain 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 mine new blocks, creating transactions, and securing your blockchain, you'll gain an in-depth understanding of how a blockchain functions.
As you make your way through the chapters, you'll learn to build an APIserver to interact with your blockchain and understand how to host this server on a decentralized network. You'll also learn about the consensus algorithm and use it to verify data and keep network nodes synchronized. In the concluding chapters, you'll build your own blockchain prototype in code and gain a thorough understanding of how blockchain technology actually works and why is it so secure and valuable.
By the end of this book, you will have understood how decentralized blockchain networks function and why decentralization is such an important feature for securing blockchain.
