Abstract
A computer-implemented method and device for implementing identity endorsement on a blockchain are provided. In some embodiments the method includes that: a user submits, as an applicant, certification information to a third-party certification authority, the third-party certification authority reviews and generates a certification statement, and the third-party certification authority deposits deposit information of the certification statement on the blockchain, and returns the certification statement including the deposition information to the user; an information requester requests for the certification statement from the user, and the user decrypts the certification statement and then sends the certification statement to the information requester; and the information requester checks in the blockchain, verifies validity of the certification statement and qualification of the third-party certification authority, and completes user identity certification after confirmation. According to this example solution, only deposit information of the certification statement is stored on a blockchain, which not only confirms the real identity information of users, but also does not leak the information. Moreover, without changing the architecture of the existing accounts, identity information may be added to an account and can also be verified in the blockchain.
