How to build a Decentralized Blockchain Network in Javascript

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.
