An average blockchain developer ! Because of the widespread adoption of cryptocurrency, the demand for blockchain developers is at an all-time high. makes about $146,000 a year In this article, I present to you a roadmap and some of the best resources to kick-start your journey as a blockchain developer. Who Is a Blockchain Developer? A blockchain developer is one who creates and maintains the blockchain network. They are in charge of optimizing blockchain protocols, developing internal blockchain systems, and creating smart contracts and web apps. To prevent hacks or strategic changes, most employers will require their developers to store all blockchain data. They are also responsible for creating the interfaces to maintain client applications and security. Steps to Become a Blockchain Developer 1. Understand Blockchain Fundamentals To become an expert at a skill, learning the fundamentals is a great starting point. Before delving into blockchain development, you need to first understand . Understanding how the blockchain came to be will help you know how to use it to develop blockchain applications. what a blockchain is , , , and can keep you updated on the fundamentals of blockchain. Tutorials guides courses training 2. Understand the Basics of Decentralized Applications and Ethereum According to the journal , "A decentralized application" is an application that can operate autonomously, typically through the use of smart contracts, and runs on a decentralized computing, blockchain, or other distributed ledger system. Blockchain Technology in Energy is a technology for developing apps and transacting globally without the constraints of a centralized authority. Ethereum Because of the security and rich ecosystem of this technology, decentralized apps are often built with Ethereum. A solid understanding of decentralized applications and Ethereum is a must for blockchain development. 3. Learn the Basics of Web Development Web development is divided into two parts: the front end and the back end. The front end is concerned with the user interface, or the visual aspect of your application with which prospective customers or visitors will interact. The backend had to do with the server and application working behind the scenes to give you that visual side. Having a good knowledge of web development will help with your transition into blockchain development. 4. Understand What a Smart Contract Is Working as a blockchain developer will involve using smart contracts. A smart contract is a computer protocol that is stored on a blockchain and is designed to digitally facilitate, verify, or enforce contract performance. Learning C++, Golang, and Python is cool, but to stay relevant, you need to have a good grounding in (the most popular language for building smart contracts). Solidity 5. Understand How to Connect Your Smart Contracts to the Front End After building the smart contracts, connecting them to the front end is your next step. For blockchain development, you can rely on two main libraries to do this: web3.js and ether.js. Web3.js provides a single instantiated web3 object with methods for interacting with the blockchain, while ethers.js . divides the API into two distinct roles Depending on your project, you can choose one of the libraries to run your applications. 6. Begin Building Although there are so many frameworks, libraries, and deployment tools to choose from, the most important step is to begin building. There are and communities that can help you navigate these processes. But you first have to build something, even if it isn't a kickass project. courses It can be an NFT marketplace, a game, a decentralized finance app, or even a homepage. Just start! How to Become a Blockchain Developer: How These 10 Pros Did It As a blockchain developer, your job is to create applications on the blockchain for everyone. A lot of people want to be blockchain developers but are confused about where to start. In this article, I want to address your fears.

For tools, I use to test. truffle Can You Give Practical Advice to Newbies Who Want to Become Blockchain Developers? If you want to start with Web3, I advise you to understand and hone Web2 technologies first. Since this is blockchain development, start with web development and build further. Web3 is an advanced version of Web2, not a totally different thing. 3. Sami Ullah Salim Community Builder at Amazon Web Services How Did You Get Into Web3 as a Developer? I started with Web3 by reading about it online in various articles and blog posts. This led me to discover the various potentials of blockchain technology. Blockchain helps us create a decentralized ledger (meaning anyone can access the data, but it is immutable). It also helps us create non-fungible tokens. In Web3, you don't have to create or maintain different accounts for different websites. You can have a wallet that is created using the blockchain, and you can use it to log in or sign up. What Is Your Favorite Project You’ve Worked On, and How Did You Go About It? I created multiple projects in the blockchain. The recent one was a website where people could log in with their wallets and see their remaining balance. They are listed on my profile. For tools, I use for testing and Solidity as a programming language. To integrate smart contracts with the on the web, I also use etherJs and web3Js. Hardhat React library Can You Give Practical Advice to Newbies Who Want to Become Blockchain Developers? Start learning the theory of blockchain. It's important to understand its concepts because you will be building on them. Then start learning because it's mostly used for smart contract development. Solidity For integrating parts, learn React Library, EtherJs, or Web3Js. You can learn these things from multiple websites and courses. Most of all, start doing projects. You can create your token or your NFT Marketplace. 4. Olubisi Idris Ayinde Developer Relations Engineer at Mara How Did You Get Into Web3 as a Developer?

Everything started in 2017 when I saw an article about Bitcoin in . Wired Magazine I hadn't paid much attention to it before, but when I read that article, the idea of a distributed ledger technology that could eliminate the middleman and run autonomously resonated in my head. After that, like everybody else, I stumbled upon the and started to learn more information and documentation about decentralized technologies. Bitcoin white paper I remember that during that time we had a small group of crypto enthusiast engineers that met on the coffee corner to talk about cryptocurrencies, decentralized technologies, and Web3 projects. After working on a trading engine for a TradFi company, we decided to look for some funding to launch our own crypto exchange. In 2018, I was eager to join the Web3 ecosystem, and I met . Mario Alves We discussed some preliminary ideas and decided to collaborate to launch . Taikai This is a Web-based social innovation network that will connect developers and organizations on a decentralized platform with a tokenized circular economy based on the KAI Token.

What Is Your Favorite Project You’ve Worked On, and How Did You Go About It? My favorite project is, of course, . TaiKai This project was a challenge to build and took years to reach the maturity that it has right now. I don't believe you can build an outstanding product in a couple of weeks. It took some months to understand our market and drive the product in the best direction. But one funny thing is that some of the early designs that we made on our first office whiteboard still stand and were important in our journey. We are currently expanding our product to interoperate with external Web3 social graphs. Like many other projects, we use unit tests for smart contracts, UI design systems, and a full suite of end-to-end tests that validate our software in an automated way, just to make sure we have a healthy production build.
