Build 5 Dapps on the Ethereum Blockchain - Beginner Tutorial

via freeCodeCamp


This course teaches how to build 5 decentralized applications (Dapps) on the Ethereum Blockchain. By the end of the course, students will be able to develop smart contracts, test them, and build web frontends to interact with the contracts. The course covers the architecture of Dapps, Solidity programming language, Remix IDE, Truffle framework, Ganache local Blockchain, Web3 JS library, Metamask wallet, and deployment to public testnet and mainnet using Infura API. The teaching method includes hands-on development of Dapps with step-by-step guidance. This course is designed for beginners interested in learning Ethereum Dapp development and blockchain technology.
