How to Become a Blockchain Developer in 2022

Blockchain technology of distributed ledger has revolutionized and redefined a large number of businesses, sectors, and industries. The technology opens a new gate to tech enthusiasts or any individual wanting to build their career as a blockchain developer in 2022.

Blockchain is a shared, immutable ledger to record transactions and track assets in a business network. An asset can be tangible (a house, car, cash, land) or intangible (intellectual property, patents, copyrights, branding). Virtually anything of value can be tracked and traded on a blockchain network, reducing risk and cutting costs for all involved. Blockchains use distributed ledger technology by creating network nodes.

Blockchains are an integral part of the backend when it comes to provide crypto services. Individual nodes are created to keep the encrypted information of the cryptocurrency forming a thread like structure. These nodes combine and create a blockchain. The entire connectivity is done using distributed ledgers.

To become a blockchain developer, you can take up an online course that will provide a deeper understanding of blockchains including detailed information about the working of  Ethereum, IPFS, Hyperledger, and R3 Corda.

To explore more about becoming a competitive Blockchain developer, let’s dive in to discover the detailed knowledge.

Why Should I Learn Blockchain Technology?

Why should I learn Blockchain

Becoming a blockchain developer is a rewarding, and exhilarating choice to start your career. For learning blockchain technology, you must have a strong passion for learning Blockchain, its ecosystem, and how it works. Ultimately, the answer to the question is “ Why should you become a blockchain developer? – must be clear in mind. The experts give the following reasons to choose blockchain development:

  • Less Competition in the Job Market
  • Higher Salaries with a better understanding of the Crypto Market
  • Take the first movers’ advantage
  • You can start building your Blockchain applications

Here are some tips to start with:

  • Start learning the fundamentals and the process of the way blockchains operate.
  • Ethereum and dApps are the starting points. Front-end and Backend development resources will help you develop a better understanding of the blockchain rabbit hole
  • Learning Smart Contracts, Solidity, and Resources
  • Other tools that help in creating, managing, and organizing blockchains

Knowledge about Web 2.0

Understanding the Web 2.0 standards and hands-on experience in web development technologies is important to start blockchain technologies. Knowledge about React.js, and Next.js will be beneficial because Decentralized applications aka DApps have a standard vanilla Javascript or Javascript framework frontend.

Learn the Fundamentals of Blockchain

To become a Blockchain developer, you need to understand what a blockchain is? how does it work? and why and when do we use it?

You first need to know what you are working with. The foundation course for the blockchain covers the following topics;

  • What is a Blockchain?
  • How does it work?
  • How to interact with Blockchain?
  • How to connect web applications to your Blockchain?

However, It is a suggestion to start working with Ethereum blockchain as it is very popular and It has a strong dev community.

Learn about Smart Contracts

A smart contract, like any contract, establishes the terms of an agreement. But unlike a traditional contract, a smart contract’s terms are executed as code running on a blockchain like Ethereum.

It allows the development of apps that take advantage of blockchain security, reliability, and accessibility while offering sophisticated peer-to-peer functionality — everything from loans and insurance to logistics and gaming.

Learn Solidity, The language for Smart Contracts

Solidity is known as the language of smart contracts. Solidity is an object-oriented, high-level language for implementing smart contracts. Smart contracts are programs that govern the behavior of accounts within the Ethereum state.

Solidity is a curly-bracket language designed to target the Ethereum Virtual Machine (EVM). It is influenced by C++, Python, and JavaScript. You can find more details about which languages Solidity has been inspired by in the language influences section.

Solidity is statically typed and supports inheritance, libraries, and complex user-defined types among other features. With Solidity, you can create contracts for uses such as voting, crowdfunding, blind auctions, and multi-signature wallets.

Learning Decentralized applications

After getting familiarity with smart contracts and solidity, you are ready to build, test and deploy your smart contracts. Now, you will need a user-friendly interface as the frontend so the end-user can interact with your dApp. In the frontend interface, you create a dApp (Decentralized Application). dApp can be a mobile or web app but in most cases, it is a web app. Web apps are usually like regular web apps using HTML, CSS, and Javascript.

While building your app, the two most important tasks are:

  • Integration with Blockchain
  • Integration with Wallet

For the integration with blockchain, a javascript library web3.js is used.

Learn about MetaMask or any other Crypto wallet

A blockchain wallet is a digital wallet that allows a user to store and manage their funds like Bitcoin, Ether, and other cryptocurrencies. The wallet is used to exchange funds quickly. These transactions are cryptographically signed and therefore, are secure. The wallet is accessible from mobile apps and web apps. A blockchain wallet provides all the necessary features for safe and secure transfers and exchanges of funds between different parties. It is very similar to sending or receiving money through PayPal or any other gateway used today, but you use cryptocurrency instead.

There are lots of blockchain/crypto wallets. I would suggest initially going with Metamask. Metamask allows users to access their Ethereum wallet through a browser extension or a mobile app.

Learn web3.js and ether.js to connect smart contracts to dApp

Now you will have a user interface application (frontend application) and a blockchain (smart contract). Now you’ll need your frontend to interact with the blockchain. The two most popular for this purpose are, web3.js and ether.js.

Web3.js is a collection of libraries that allow you to connect with a local or remote Ethereum node using HTTP, Websockets, & other communication protocols directly from your JavaScript Based front-end. Ethers.js is a lightweight  JavaScript library used.to connect the JavaScript front-end with Smart Contacts as an alternative to Web3.js.

Learning the Role Of Blockchain Developer

The main role of a blockchain developer is to build applications by using expertise and knowledge in areas such as smart contracts design/development, API, design/development, security, cryptography, data analysis, UI/UX, blockchain analysis, project management, blockchain architecture design, and more

To start, you can become a  junior blockchain analyst, developer, senior developer, or team leader. and so on. The salary package of blockchain developers is higher compared with other developers. Innovation and lesser expertise are the main reasons for it.

Skills Needed to Become a Blockchain Developer

If you have the knowledge of software development and you understand the core processes to develop a decentralized system, you can become a blockchain developer. 

Some of the main skills to become a blockchain developer are:

  • Cryptography: hashing algorithms, wallets, keys, digital signatures
  • Programming Languages: Solidity, C, C++, Rust, Go, Javascript

Top Blockchain Development Tools

Having the right tools for the job is half the battle, the other half is mastering how to use them. So, when you are on your way to becoming a blockchain developer, make a learning list of things that are mentioned here ;

IDE (Integrated Development Environment)

For smart contracts when starting https://remix.ethereum.org  has everything you need in one place. You can use it as an online text editor, compile and debug contracts and even migrate code and execute smart contract functions via injected web3.

Once a blockchain developer starts to take on more complex projects with dependencies and multiple files it’s often worth moving to an offline locally hosted solution. There are two strong options here: Hardhat and Truffle.

Truffle was the original node js application that has been used for many years to compile and migrate Solidity code to the blockchain. Hardhat is newer and has some design improvements and feature benefits. Which you choose is a personal decision and both do the same job in only very subtly different ways.

Text Editor

Once you have Truffle Suite or Hardhat installed, the text editor like VS Code from Microsoft. Will help you do simpler coding.

Browser & Wallet

You’ll also need a web browser and a digital wallet to hold funds and pay transaction fees. Google’s Chrome browser and Metamask again are obvious choices. Metamask can be configured to work with any EVM compatible blockchain by adding networks. For Solana development, there is the excellent Phantom App.

Terminal

A terminal is like an old-school MS-DOS prompt where you can run things from a command line. 95% of blockchain stuff can be run on Windows, Mac, or Linux. If you are a windows user then you can use the Powershell terminal, just hit the windows key and type PowerShell to launch a terminal. Occasionally node software can only be run on Linux or via docker which will require either a cloud instance or a VM like WSL (Windows Subsystem for Linux). However, the developers prefer to use Windows and Linux via WSL.

Access Point

An access point provides an API to interact with to send transactions to a decentralized network. So the web3 javascript code will connect to an access point, sometimes called an RPC provider and that will relay messages to the rest of the nodes that form a peer-to-peer blockchain network.
