Web1 is the first stage of the Internet. It is mainly based on static web pages. Users can only view and browse web content through browsers. The interactivity is poor, mainly including text, pictures and other information. Think of it as a newspaper that can only be read.
Web2 is the second development stage of the Internet. In this stage, Web technology has developed rapidly, mainly manifested in more interactive, higher social, stronger personalized services, richer media forms, and the emergence of Many emerging network applications, such as Facebook, Twitter, YouTube, etc. Web2 is mainly centralized, with a small number of controllers controlling most of the data and algorithms.

Web3 is the third development stage of the Internet. In this stage, Web technology will continue to develop, mainly in the form of decentralization, smart contracts, and encrypted currencies. The goal of Web3 is to build a decentralized network. The simple understanding is that users have more control over their own data and information, and can directly conduct digital transactions and interactions.
Therefore, the main difference between Web3 and Web1 and Web2 is that Web1 and Web2 mainly focus on static web pages and more interactive web pages respectively, while Web3 is committed to building a decentralized network that enables users to better control themselves data and information .
