This Blockchain & Web3 course provides a strong foundation in distributed ledger technology, Ethereum blockchain architecture, consensus mechanisms, and decentralized systems.
You will learn to write smart contracts in Solidity, interact with the blockchain, and build decentralized applications using Web3.js / Ethers.js.

The course also covers token standards, NFT creation, DeFi basics, and modern Web3 frameworks like Hardhat, Truffle, and IPFS for decentralized storage.
By the end, learners will be able to develop, deploy, and manage blockchain-based applications confidently.
