Learn blockchain development — from smart contracts to DeFi applications. While the hype has cooled, the technology is maturing and Indian companies are actively building Web3 products.
Understand blockchain from first principles: distributed ledgers, consensus mechanisms, cryptographic hashing, and how Bitcoin/Ethereum work.
By the end, you'll be able to
Mini-project
Build a simplified blockchain in Python: blocks, hashing, proof-of-work, and validation.
Learn Solidity — the language of Ethereum. Master smart contract development: syntax, patterns, security, and gas optimization.
By the end, you'll be able to
Mini-project
Build a smart contract for a token-gated voting system: token creation, proposal submission, voting, and result tallying.
Connect frontends to blockchain. Learn ethers.js/web3.js, wallet integration (MetaMask), and how to build dApp UIs.
By the end, you'll be able to
Mini-project
Build a decentralized marketplace UI: connect wallet, list items, buy/sell, and display transaction history.
Understand DeFi protocols: ERC-20 tokens, ERC-721 NFTs, AMMs, lending protocols, and how money flows in decentralized finance.
By the end, you'll be able to
Mini-project
Build a simple DeFi protocol: ERC-20 token, staking contract with rewards, and a basic frontend.
Security is non-negotiable in blockchain — bugs lose real money. Learn common vulnerabilities, auditing tools, and security best practices.
By the end, you'll be able to
Mini-project
Audit 5 smart contracts for vulnerabilities. Write a security report for each with findings and recommendations.
Ethereum is expensive. Learn Layer 2 solutions: Polygon, Arbitrum, Optimism, and how to deploy and bridge between chains.
By the end, you'll be able to
Mini-project
Deploy your DeFi protocol on Polygon. Implement a bridge UI for moving tokens between Ethereum and Polygon.
Build a Web3 portfolio: deployed contracts on testnets/mainnets, open-source contributions, and participation in hackathons.
By the end, you'll be able to
Mini-project
Deploy your best project on a testnet. Write documentation. Participate in a Web3 hackathon (ETHGlobal, Devfolio).
