Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for blockchain-based cross-entity authentication are provided. One of the methods includes: obtaining, from a blockchain, a blockchain transaction comprising an authentication request by a first entity for authenticating a user, wherein the authentication request comprises a decentralized identifier (DID) of the user; in response to determining that the first entity is permitted to access authentication information of the user endorsed by a second entity, obtaining an authentication result of the user by the second entity in response to the obtained blockchain transaction, wherein the authentication result is associated with the DID; generating a different blockchain transaction comprising the authentication result; and transmitting the different blockchain transaction to a blockchain node for adding to the blockchain.
