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.

Introduction to RxJS – Extensions for JavaScript Reactive Streams

Reactive Extensions for JavaScript (RxJS) is a precise alternative for callback or Promise-based libraries. It treats any ubiquitous source of events in the exact same manner, whether it is reading a file, making an HTTP call, clicking a button, or moving the mouse. RxJS is built on top of the pillars of functional and reactive programming, as well as a few popular design patterns such as Observer and Iterator.
