Zusammenfassung:	The invention provides a block chain DID management method, device and system, and the method is applied to a registered block chain, and comprises the steps: monitoring a first DID smart contract on the registered block chain; when a new DID is successfully registered in the first DID smart contract, collecting DID data original texts of all registered DIDs; generating a Merkel tree according to all the collected DID data original texts of the registered DID; and submitting a first Merkel root of the Merkel tree to a second DID smart contract of each application block chain, wherein the first Merkel root is used for the second DID smart contract in the application block chain to perform legality verification on the subsequently imported DID data original text registered with the DID. According to the method, the unified DID can be registered and used on a plurality of application block chains, the correctness of the DID can be ensured, and different account addresses can be used on different application bloc
