Web3 represents the next evolution of the internet, aiming to decentralize control and empower users through blockchain technology. Unlike Web2, where data is owned by corporations, Web3 uses decentralized networks like Ethereum to give users ownership of their digital assets and identities. It enables trustless interactions, smart contracts, and token-based economies. This shift supports greater transparency, privacy, and innovation in sectors like finance, gaming, and social media. While still developing, Web3 promises a more democratic digital future where power shifts from centralized platforms to individual users and communities. However, scalability, regulation, and usability remain challenges to overcome.
