System and method for creating decentralized identifiers
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for decentralized-identifier creation. One of the methods includes: receiving a request from a first entity for obtaining a new decentralized identifier (DID) for a second entity; determining an existing DID associated with the first entity based on the request; generating a cryptographic key pair associated with the second entity comprising a public key and a private key; creating, based on the public key, a DID document associated with the new DID, wherein the DID document comprises the existing DID associated with the first entity; generating a blockchain transaction for adding the DID document to the blockchain; signing the blockchain transaction using the private key of the cryptographic key pair associated with the second entity; and sending, to a blockchain node associated with the blockchain, the signed blockchain transaction for the blockchain node to add to the blockchain.
