Foundations of Web3

Abstract

This chapter establishes the intellectual groundwork for the shift from traditional web paradigms to a decentralized digital future. It begins by tracing the evolution from Web1 – a static, information-centric era – to Web2, characterized by interactive, user-generated content and the rise of social media. The chapter then introduces Web3 as a transformative leap, driven by blockchain technology, digital wallets, and decentralized applications (dApps) that empower individuals with true ownership over their digital assets and data. Real-world examples in decentralized finance, non-fungible tokens, and social networks illustrate how these innovations challenge centralization and reshape online interactions. Additionally, the discussion highlights ongoing challenges such as usability, security, and regulatory uncertainty, laying a solid foundation for understanding Web3’s revolutionary potential.
