Credit Link

Credit Link extension Credit Link is a loyalty-points credit card based on blockchain and DID decentralized identity authentication technology. It can be issued on any blockchain (consortium, public, or private) and provides user-based decentralized information certificates for the blockchain network on which it operates. Certificate information is registered anonymously on-chain as NFTs. Users can present their credentials through the Credit Link mobile client app to merchants that need to authenticate ownership of the credential information. Credit Link automatically checks whether the anonymous on-chain information matches the user's information, triggering processes such as user authorization, event authenticity verification, or loyalty-point inquiries and deductions.
