A Guide on How to Build a Blockchain with Javascript

Although JavaScript is now the most widely used programming language worldwide, it is not usually the first language that comes to mind for building a blockchain. This could be because JavaScript is frequently regarded as a front-end technology, despite the continuous development and use of Node.js. Lisk changes everything about that misconception and empowers Javascript developers to build powerful blockchains.

The goal of this article is to teach you how to build Javascript Blockchains with the Lisk SDK. By the end, you will be able to utilize it to build your own blockchain application using JavaScript.
