Dive into a comprehensive tutorial series on Ethereum, exploring its architecture and core concepts for developers. Begin with an overview of smart contracts and decentralized applications (dApps), then delve into Ether, cryptographic keys, account addresses, and transactions. Examine the blockchain structure, blocks, and mining process, and compare Proof of Stake and Proof of Work consensus mechanisms. Learn about gas and fees in the Ethereum network, and set up a MetaMask wallet. Gain hands-on experience by writing a smart contract using Remix, and conclude with an introduction to development tools like WebStorm, Truffle, and Ganache, including an in-depth look at Truffle migrations.
