In previous post, we have a single Blockchain and the only way to access it is through API from a single server. It is centralized and not good because this API totally controls the whole Blockchain with all data inside it. Today we will build a decentralized Blockchain network that has many different instances of the API. So instead of just having our Blockchain hosted on a single centralized node, it is hosted across a decentralized network which will be very powerful because of the security: we don’t have to trust only one single entity.

The WebSocket protocol provides new capability for web applications: full-duplex, two-way communication. So in the system where the client and server need to exchange data at high frequency and with low latency, WebSocket is the best solution. In this tutorial, we’re gonna create a Spring Boot Application that uses WebSocket protocol to communicate with Angular 5 Client.
