This article presents a structured and accessible overview of the internet's evolution across three distinct phases: Web1, Web2 and Web3. Beginning with the static, read only nature of early internet infrastructure in the 1990s, it traces the shift toward interactive, user generated content in the Web2 era and the centralised control that accompanied it. The article then introduces Web3 as a decentralised paradigm built on blockchain technology, where digital ownership, verified through cryptography, is returned to individual users rather than concentrated in corporate platforms. Key concepts including blockchain, cryptocurrency, digital wallets, decentralised finance, non-fungible tokens and decentralised autonomous organisations are explained in plain language for a beginner audience.The article argues that the defining characteristic of Web3 is not merely technological advancement but a structural redistribution of power and value from institutions to individuals. It concludes by framing digital ownership as an increasingly critical issue in an era where significant portions of human activity, identity and commerce exist online.
