Skills Required for Blockchain Developer from Scratch

If you’re looking to become a blockchain developer, there are a few skills required for blockchain developer which you should know.

First, blockchain is still a relatively new technology, so there aren’t as many jobs in this field as there are in more established tech fields.

However, demand and salary of blockchain developers is growing rapidly, so now is a great time to get started in this field.

Second, because blockchain is such a new technology, there is no one “standard” way to develop for it. This means that you’ll need to be comfortable learning new things and experimenting as you go.

There are a few different programming languages that are commonly used for developing blockchain applications, so you’ll need to choose one (or more) to focus on.

If you’re interested in becoming a blockchain developer, then you should keep reading this article to know the skills required for blockchain developer.

7 Skills Required For Blockchain Developer

Command Line

While getting used to command line is essential for any budding software developer. At first it can be seen like geeky but once you get used to it, let me tell you, you won’t even work without it.

The best place to start is by learning on a Unix or a Linux command line interface and if you have a Mac the CLI is Unix based so the built in terminal is great to start and if you are using a Windows machine try using segment Linux emulator.

Do remember that main point for learning a command line interface is to learn how to interact with computer using commands rather than point and click interface.

JavaScript

JavaScript is a primarily an internet language. It’s supported by evey web browser available and most web pages have at least some JavaScript running on them. It’s a client side scripting language so the code is sent to the client that is web browser which performs the computation that is in contrast to PHP.

For example where the computation is done on the server and the resulting markup is sent to the client. Want to learn Java script for free then read our post Top 10 Free JavaScript Courses.

NodeJS

NodeJS is an open source cross platform javascript runtime environment that executive the javascript code outside the web browser. NodeJS enables developers to write server side application with javascript.

The breadth of the framework which runs on nodejs allows any form of application to be created and be deployed on top of a node and not many people know this but many blockchain frameworks are built on top of nodejs.

Blockchain Basics

Once you’re familiar with the first three steps, it’s time to jump into blockchain technology and learn the basics. Try learning answer to the questions lile What is blockchain? How does it work? What are the consensus mechanisms? What is a node? What is a smart contact? etc.

Understanding the basics of these questions is vital to create useful blockchain application.

So by now you’ve got some coding experience but don’t know where to start with blockchain. To become a blockchain developer you need to gain some blockchain specific skills. These are the skills needed to start developing solutions on blockchain and more specifically the ethereum ecosystem.

Solidity

Solidity is an object-oriented programming language for writing smart contracts. It is used for implementing smart contracts on various blockchain platforms most probably ethereum.

If you have experience with javascript, c++ or any other modern object-oriented language, the syntax of solidity will be easy to pick up as it is heavily influenced by these languages.

Do note that smart contracts are immutable by that I mean that it is an object whose state cannot be modified after it is created. So instead of incrementally improving your smart contract with new releases, once a smart contract is deployed it cannot be changed.

Web3.js

Web3.js is a collection of libraries that allows you to interact with local or remote ethereum node, using a HTTP or IPC connection. Web3.js bridges the gap between the traditional internal and the decentraziled world.

It’s used to connect an ethereum blockchain to a client browser usually through a browser extension like metamask. Unfortunately the most common web browsers don’t support web3 out of the box, which is the reason for having to use metamask for this purpose.

The web3 library is easily installed into javascript object and allows your decentralized application to run and retrieve information to and from a blockchain defined by the user.

Truffle Suit

The truffle suit gets developers from idea to decentralized application as comfortably as you can think. Truffle is a framework which facilitates the development, testing and deployment of full-stack decentralised applications.

It comes with a few amazing parts to it which include
Framework: It provides a great development environment where you can write and deploy smart contracts within minutes. It’s testing framework is also easy to use with a choice of both solidity and javascript to test your smary contracts with.
Ganache: It allows you to start a local blockchain in your development environment with just two clicks and makes developing decentralized applications on your machine extremely easy.

Conclusion: Skills required for Blockchain Developer

A blockchain developer is responsible for developing and implementing distributed ledger technology-based solutions to business problems. They work with clients to understand their requirements and then design, build, test and deploy blockchain applications.

Blockchain developers must have a strong understanding of distributed ledger technology, cryptography and smart contract development. They should also be able to build and maintain web applications.
