Web 3.0 is the next evolution of the internet, focused on decentralization, user control, and privacy. Unlike Web 2.0, where data is controlled by central platforms, Web 3.0 allows users to own and control their digital identities and assets through technologies like blockchain and cryptocurrencies. It enables secure, peer-to-peer transactions and features decentralized applications (dApps), enhanced by artificial intelligence (AI) and machine learning for smarter, more personalized online experiences.
