Web3, short for "Web 3.0," represents the next evolution of the internet, where users gain more control over their data, digital identities, and online interactions. Unlike Web2, which is dominated by centralized platforms like Facebook or Google, Web3 operates on decentralized networks, primarily built on blockchain technology. This shift aims to create a more open, transparent, and user-centric internet, where trust is established through code rather than intermediaries. Web3 introduces key concepts such as decentralized finance (DeFi), non-fungible tokens (NFTs), and decentralized autonomous organizations (DAOs), which empower individuals to engage in a truly peer-to-peer digital economy.
