Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for mapping decentralized identifiers (DIDs) to real-world entities. One of the methods includes: receiving, by a server system, a request for obtaining a DID, the request comprising an identifier of a subject corresponding to the DID and a proof of identity authentication of the subject; creating, by the server system, a DID document corresponding to the DID, wherein the DID document comprises a mapping relationship between the proof of identity authentication and the DID; generating, by the server system, one or more blockchain transactions for creating the DID and adding the DID document to a blockchain; and sending, by the server system to one or more blockchain nodes associated with the blockchain, the one or more blockchain transactions for adding to the blockchain.
