# Universal Basic Asset Universal Basic Asset introduces the concept of UBI, through research and analysis of users and their relationships, transforms the user relationships that originally existed off-chain to the chain, establishes a user relationship network on the chain, and uses the UBA network rating and analysis mechanism to cooperate with PageRank and other algorithms , to accurately analyze users and open it to WEB 3.0 developers. Universal Basic Asset uses zero-knowledge proof to build a user data privacy layer. Through this privacy layer, users can still prove their identity and the validity of their identity tags without exposing their data to the chain. In this way, the SocialFi network and Decentralized Identity (DID) system with privacy protection in WEB 3.0 are constructed. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
