Blockchain is the underlying technology that powers decentralized networks and stores transaction data, while Web3, also known as "Web3.0" or the "Decentralized Web," refers to the next generation of the internet that leverages blockchain and other decentralized technologies to create a user-centric and trustless digital ecosystem. In essence, Web3 utilizes blockchain's features, such as smart contracts and decentralized applications (DApps), to enable more secure, transparent, and decentralized interactions on the internet.
