Foundations of Web3, Ethereum, and Smart Contracts

The transition from the traditional internet to Web3 is reshaping how we handle data, ownership, and digital trust. Understanding the core mechanics of blockchain technology is essential for anyone looking to participate in the future of the digital economy. This text-based course guides you from absolute beginner to a confident grasp of decentralized networks. By reading clear explanations and studying real-world smart contract code snippets, you will understand how Ethereum operates, how decentralized finance functions, and how modern decentralized applications are structured. What you'll learn: Understand the fundamental shift from Web2 to decentralized Web3 architectures; Explore the core mechanics of the Ethereum blockchain, including consensus mechanisms and gas fees; Analyze the structure of Solidity smart contracts through written code walkthroughs; Learn how decentralized finance protocols and token standards like ERC-20 operate; Examine modern Web3 concepts, including Layer 2 scaling solutions and basic smart contract security practices; Practice reading and interpreting decentralized application workflows and transaction flows. You will begin by learning foundational terminology and the historical context of blockchain technology before moving on to Ethereum's architecture. The course then transitions into practical concepts, guiding you through the logic of smart contracts and the economic principles of decentralized networks. This course is designed for curious beginners, aspiring developers, and tech enthusiasts who want a solid conceptual foundation in Web3 without needing prior programming experience.
