Dive into a comprehensive 4-5 hour tutorial on building decentralized applications (Dapps) on the Ethereum blockchain. Learn to develop, test, and create web frontends for five different Dapps, covering essential topics such as Solidity programming, smart contract development, and integration with Web3. Explore the architecture of Dapps, utilize tools like Remix, Truffle, and Ganache, and gain hands-on experience with Metamask and deployment to public testnets and mainnet using Infura API. Master the creation of smart contracts, testing methodologies, and frontend development techniques while building a diverse portfolio of Ethereum-based applications.
