To become a blockchain developer and learn all stacks of development, you can follow this learning path:
- Solidity: Start with learning Solidity, a programming language used to write smart contracts on the Ethereum blockchain. You should learn the syntax, data types, control structures, functions, and object-oriented programming concepts in Solidity.
- Ethereum: Next, learn about the Ethereum blockchain, including its architecture, consensus mechanisms, transaction execution, gas fees, and Ethereum Improvement Proposals (EIPs).
- Smart Contracts: Once you have learned Solidity and Ethereum, dive deeper into writing and deploying smart contracts on the Ethereum blockchain. You should learn about contract design patterns, security best practices, and testing frameworks like Truffle and Ganache.
- Web3.js: It’s essential to master Web3.js to interact with smart contracts from a web application. Learn how to connect to the Ethereum network, send transactions, and read data from smart contracts using Web3.js.
- Backend Development: To build decentralized applications, you need to have a good understanding of backend development. Learn how to build REST APIs, connect to databases, and handle HTTP requests using frameworks like Node.js and Express.js.
- Frontend Development: To build user interfaces for your decentralized applications, you should learn modern frontend technologies like React, Redux, and Vue.js. These frameworks will help you build interactive and responsive UIs that can communicate with smart contracts.
- IPFS: Learn about InterPlanetary File System (IPFS), a distributed file storage system that allows for decentralized hosting of content. You can use IPFS to store large files like images and videos for your decentralized applications.
- Blockchain Platforms: Lastly, learn about other blockchain platforms like Polkadot, Binance Smart Chain, and Cosmos. These platforms offer different features and capabilities, and it’s good to have a broad understanding of the blockchain ecosystem.
As you progress through this learning path, start building small projects to apply what you have learned. Focus on building decentralized applications that solve real-world problems and demonstrate your skills to potential employers. Good luck!
