Web 2.0 refers to the second generation of the internet, characterized by user-generated content, social media platforms, interactive web applications, and centralized services. Companies like Facebook, Google, Twitter, and Amazon define the Web 2.0 era. In crypto discussions, Web 2.0 is contrasted with Web3, which envisions a decentralized internet where users own their data, digital identity, and assets through blockchain technology. The transition from Web 2.0 to Web3 represents a shift from platform-controlled to user-controlled digital experiences.
