Blockchain has become a buzzword recently. It’s the basis for cryptocurrency, and many are discussing turning to it to improve digital security. It has also been sparking innovation across many industries, including healthcare, finance, and supply chain management.
But what does it take to become a blockchain developer? And is it a promising career choice? Here’s everything you need to know if you’re considering a future in this rapidly growing field.
What is blockchain development?
A blockchain developer designs, implements and maintains a blockchain system, which can include decentralized applications and smart contracts. The developer will usually specialize in a specific area, like core blockchain development, which focuses on the architecture and protocols.
Another area a developer can specialize in is dApp development, which concentrates on building applications on top of blockchain platforms like Ethereum or Solana.
Steps to becoming a blockchain developer
Build a strong foundation in computer science
First, you need a strong foundation in computer science. Having proficiency in languages like C++, JavaScript, Python, and Solidity (the main language for Ethereum smart contracts) is crucial.
You will also need to understand how data structures like linked lists, hash maps, and graphs work, as well as have a solid understanding of hashing, public-key cryptography, and encryption techniques.
Understand blockchain technology and its fundamentals
Blockchain has a steep learning curve, so it’s essential to understand how it works completely before attempting to get into the field. Learn about algorithms, like Proof of Work (PoW) and Proof of Stake (PoS), which are essential to how they can maintain a decentralized nature.
Try to gain some hands-on experience with smart contracts, which are self-executing contracts coded on blockchains. Ethereum is the most popular platform for smart contract development. You will also want to gain experience by building dApps on platforms like Ethereum, Polkadot, or Binance Smart Chain.
Get familiar with blockchain development tools
Several tools and frameworks can help simplify the blockchain development process.
- Truffle is an Ethereum development framework that simplifies the creation and testing of dApps.
- Ganache is a local blockchain that you can use to test your smart contracts.
- MetaMask is a browser extension that acts as a wallet for interacting with Ethereum and other blockchain networks.
- Remix is a browser-based IDE that allows for smart contract development on Ethereum.
Gain hands-on experience
Join open-source blockchain projects: Many blockchain projects, such as Bitcoin and Ethereum, are open-source. Contributing to these projects can help you gain hands-on experience.
Participate in hackathons: Blockchain hackathons are a great way to test your skills, learn new things, and network with other blockchain developers.
Build your portfolio: Create a portfolio of dApps and smart contracts you’ve built. Showcase these on platforms like GitHub or a personal website to attract potential employers.
Is becoming a blockchain developer a good idea?
Pros
- Blockchain developers are in high demand, and their salaries are often above the industry average. According to recent studies, the average salary for a blockchain developer can range from $100,000 to $150,000.
- Blockchain technology is evolving, and industries beyond finance, such as healthcare and supply chain, are increasingly adopting blockchain solutions, especially with the steep rise in ransomware attacks targeting these industries.
- Due to the technology’s rapid evolution, blockchain development requires constant learning and adaptation. Developers who thrive on continuous learning and enjoy solving complex problems will likely find this field rewarding.
Cons
- The blockchain industry is still relatively young, and it’s subject to regulatory changes and market fluctuations. Developers should be prepared for the industry’s volatile nature.
- Blockchain development demands a unique blend of computer science, cryptography, and finance knowledge, which can be challenging for some.
- Blockchain is bad for the environment, and it will likely require significant changes to correct that before it can become mainstream.
