Blockchain is a distributed ledger technology that enables the secure, transparent, and tamper-proof storage and transfer of information. It works by recording data in blocks that are connected in a chain using cryptography, making it almost impossible to alter or delete any information once it is recorded.
Web3, also known as the decentralized web, is a term used to describe a new generation of the internet that is powered by blockchain technology and decentralized applications (DApps). It is designed to be more secure, open, and transparent compared to Web 2.0, which is dominated by centralized web services and tech giants.
The relationship between blockchain and Web3 is that blockchain is a foundational technology that enables the decentralization of data and applications, which is essential to the development of Web3. In other words, blockchain provides the infrastructure that Web3 relies on to function, and DApps that run on Web3 often use blockchain technology to store and transmit data in a secure and decentralized manner.
