How to Become a Blockchain Developer from Scratch in 2023?

Here is a guide on how to become a Blockchain developer from scratch in 2023

Blockchain distributed ledger technology has changed and reimagined a wide range of enterprises, sectors, and industries. Blockchain is a shared, unchangeable ledger used in corporate networks to record transactions and track assets. A tangible asset (a house, car, cash, or land) can be intangible (intellectual property, patents, copyrights, branding). A blockchain network can track and sell almost anything of value, lowering risk and costs for everyone involved. By establishing network nodes, blockchains employ distributed ledger technology. The technology gives a new door for computer enthusiasts or anyone looking to start a career as a blockchain developer in 2023. Becoming a blockchain engineer is an exciting and rewarding way to begin your career. The following are the experts' reasons for choosing blockchain development:

1. Lower job market competition
2. Higher pay with a deeper understanding of the cryptocurrency market
3. Take advantage of the first movers
4. You may begin developing Blockchain applications

Blockchains are constructed from the ground up on a computer language. C++ and Python are the most often utilized programming languages for creating blockchains. Solidity is the latest trend in smart contract programming, and it is simple to create thanks to the integrated libraries provided in Solidity. Solidity is recognized as the smart contract language. Solidity is an object-oriented, high-level programming language used to construct smart contracts. Smart contracts are programs that manage the behavior of Ethereum accounts. Understanding Web 2.0 standards and having hands-on expertise with web development tools is required to get started with blockchain technologies. But first, one must understand the fundamentals, such as what a blockchain is. How does it function? What is its purpose, and when do we use it? Learning smart contacts enables the creation of apps that leverage blockchain security, dependability, and accessibility while providing advanced peer-to-peer functionality — everything from loans and insurance to logistics and gaming.

You are now ready to build, test, and deploy your smart contracts after being acquainted with smart contracts and solidity. As the front-end, you will now require a user-friendly interface so that the end-user can interact with your dApp. You create a dApp in the front-end interface (Decentralized Application). A dApp can be a mobile or web app, however, it is usually a web app. Web apps are typically built in HTML, CSS, and Javascript, just like ordinary web apps. The two most critical responsibilities when developing your app are integration with blockchain and integration with the wallet. The web3.js javascript library is used for blockchain integration.

It is also critical to learn about cryptocurrency wallets. There are numerous blockchain/crypto wallets available. An initial recommendation would be to use Metamask. Users can use Metamask to access their Ethereum wallet via a browser extension or a mobile app. Furthermore, having the proper tools for the work is just half the battle; the other half is learning how to use them. Tools like IDE, text editor, browser, wallet, and access point are very useful while constructing blockchains.

Some fantastic free learning resources include Crypto Zombies, a gamified lesson focused on smart contract development, which uses Solidity and Web3 development. It incorporates NFTs, Web3, and gas optimization. Ethereum has excellent documentation, and reading the online tutorials accessible on the official website is highly recommended. YouTube provides up-to-date knowledge that is essential to know if you want to advance in the field of blockchain. Some resources to consider include dApp University, Eat The Blocks, Eth Global, and Alysia Tech. There's SolHack, which has an active community and tutorials divided down into manageable bite-sized chunks. Hackathons allow you to learn more while interacting with the dev community. If you are wanting to raise funding, it might also be a fantastic venue to meet VCs and investors. The open-source nature of decentralized finance is a fantastic resource for both novice and seasoned developers. The great majority of projects make their code public for anyone to learn from, fork, and experiment with. These demonstrate what good Solidity code looks like, what is possible, and how to perform specific things.

One could work as a blockchain developer if you have experience with software development and understand the fundamental procedures involved in creating a decentralized system. Some of the most important competencies for becoming a blockchain developer are:

• Cryptography: hashing algorithms, wallets, keys, digital signatures
• Programming Languages: Solidity, C, C++, Rust, Go, Javascript
• Web Development: Javascript, HTML, CSS, Web Frameworks, and Libraries (Web3js, React, Angular, Vue, …)
• IDEs: Remix, Visual Studio, Eclipse
• Source Code Tracking: git, GitHub/GitLab
• Data Structures: graphs, hash trees, heaps, stacks, Patricia and Merkle trees
• Smart Contracts: design, develop, test, deploy
• Testing Tools: Metamask, Ganache, Truffle

Core blockchain developers build the architecture and security of a blockchain system, whereas blockchain software developers leverage the core web foundation and architecture developed by the core developer to create decentralized applications (dapps) and web applications, as well as smart contracts. The salary of developers is determined by the job category. It would not be appropriate to describe the net sum here, but you can be assured of a competitive wage. All you need to do is work on your fundamental talents.
