A tutorial 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 when building a blockchain. This may be because JavaScript is often seen 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. At the end, you will be able to use it to build your own blockchain application using JavaScript.

If you are a JavaScript developer new to blockchain

Are you a JavaScript developer interested in learning about blockchain but not sure where to start? You should read the blog post first Blockchain in JavaScriptwhich will give you an overview of some of the fundamental and major benefits of using JavaScript for blockchain development.

Once you’re done with that, you can start with some of our free Javascript-based blockchain application tutorials listed below. In addition, there are several educational courses and some guidance for deploying your own blockchain application concept.

Javascript Blockchain Tutorials

The Lisk SDK makes it easy to understand the intricacies of the blockchain network and related modules. Already, several tutorials are available for developers who want to understand blockchain in JavaScript.

All of these tutorials, which range in difficulty from beginner to intermediate, can be completed in 4 hours or less. Additionally, they are built on ideas that are applicable to real-world use cases and problems found in the blockchain industry.

Dashboard App and Hello World Tutorial

The first Lisk SDK the tutorial offered to developers shows how to create a “Hello World” application in keeping with the traditions of software development. Users will learn how to perform the following tasks from this tutorial:

• Initialize a basic blockchain application
• Creation of custom modules
• Custom plugin creation
• Blockchain Application Configuration
• Using Lisk Dashboard
• Unit Test modules and assets

NFT App Tutorial

NFTs are becoming increasingly popular in the crypto industry. As a result, a number of projects such as Colecti, Enevti and RGB are already under development on the Lisk network around the existing NFT concept. In addition, the upcoming Lisk SDK v6 will support a standardized NFT module.

Users can learn how to do the following by going through Lisk’s Non-fungible Token (NFT) Tutorial:

• Create an NFT-compatible blockchain application.
• Create a custom module to produce and buy NFTs.
• Create a custom plugin with additional NFT-related features.

Guidance for the Social Recovery System (SRS).

The worry of losing your money is a common problem among all cryptocurrency users. A user can lose access to their passphrase under a variety of circumstances, including accidents and theft. This social recovery system aims to alleviate some of these concerns.

Users will be able to perform the following tasks using Lisk’s Social Recovery System (SRS) guide:

• Create an account recovery tool.
• Establish a recovery configuration.

Lisk Name Service (LNS) Guide

Many blockchain applications want to use a domain name service, comparable to DNS or the Ethereum Name Service (ENS). The Lisk Name Service (LNS) training enables the development of a service where users can register .lsk domains for a predetermined period of time (1-5 years).

Users will be able to do the following after completing the Lisk Name Service (LNS) tutorial:

• Create a service that enables decentralized DNS
• Create domains with .lsk
• Configure TXT and CNAME records

Blockchain course for JavaScript

In addition to just the relevant blockchain application tutorials, we have also suggested courses to take. These blockchain courses can be the foundation of your knowledge. Listed here are a few different options specifically dealing with JavaScript in the Blockchain.

Learn Blockchain by Creating Your Own in JavaScript – Udemy

This course offers an in-depth method for learning blockchain in JavaScript. There are several video lectures about it. The content is divided into the following eight parts:

• Introduction
• Constructing a blockchain
• Blockchain access via API
• Build a blockchain network
• Coordinate the network
• Consensus
• Explore the blockchain
• Conclusion

This course will teach you how to use JavaScript to create your own decentralized blockchain network. Along the way, you will also have picked up and made use of a number of important blockchain concepts, including cryptography, algorithms, network broadcasts and much more.

An installation of Node.js and practical knowledge of JavaScript are requirements for this course.

Build a DEX with JavaScript: Start programming at Moralis Academy

Do you want to learn blockchain with JavaScript, but have little or no programming knowledge? Try this Moralis Academy course. The course begins by covering all the basics of HTML, CSS and JavaScript.

Once you’ve learned the basics of programming, you can use these skills to interface with pre-existing blockchain platforms such as 1inch and Coinpaprika. Afterwards, you will be guided through each step needed to create your own JavaScript-based decentralized exchange (DEX).

Coursera – Program for blockchain base with Javascript

This one-hour course is taught exclusively in Spanish, as the title suggests. The user will create a simple blockchain application using Node.js in this tutorial for JavaScript beginners. A brief introduction to blockchain technology precedes the definition and programming of blocks, followed by the programming and testing of an application.

Implement your own custom blockchain idea

After completing Lisk guides and perhaps a Blockchain in JavaScript Course, you will now create your own blockchain. Before you start developing, you should read How to build a blockchain to explore all your options and learn basic starting points.

Then take a look at JavaScript Web3 Projectsfor example, if you need some ideas on what to construct for your blockchain application.
