Web3.0 is a concept about the development of the World Wide Web, which is mainly related to decentralization based on blockchain, cryptocurrency and heterogeneous tokens. Users interact in Web3.0 to meet their own needs, and blockchain technology is used in the interaction to realize the creation, distribution, and circulation of value. In this way, the Web3.0 ecology is formed by the entire process of user interaction and value circulation. In contrast to Web2.0's platform centralization, Web3.0 is dedicated to realizing the "decentralized" network ecology owned and built by users. Undoubtedly, social interaction will be a breakthrough for the application of Web3.0.
