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.

Building the /register-nodes-bulk endpoint

The next endpoint that we are going to build is our register-nodes-bulk endpoint; this is the final endpoint that we need to build. These three endpoints that we have been working on will all work together to create our decentralized blockchain network.

Before we start building the endpoint, let's try to understand what the register-nodes-bulk endpoint does. Whenever a new node gets broadcast to all the other nodes inside of the network, we want to take all of the nodes that are already inside of the network and send that data back to our new node so that the new node can register and recognize all of the nodes that are already present inside of the network.

The register-nodes-bulk endpoint will be accepting data that contains the URLs of every node that is already present in the network. Then, we're simply going to register...
