Web3 is a new generation of the Internet built on blockchain, decentralization, and digital assets. Unlike traditional Web2, where data and services are controlled by large companies, Web3 allows users to independently own their data, assets, and digital identity.

Web3 technology is based on smart contracts — programs that run on the blockchain and automatically execute the terms of a transaction. They enable decentralized applications (dApps), crypto wallets, NFTs, DAOs, and other new digital tools that operate without centralized control.
