  • Patent number: 11379922
    Abstract: Data from an information storage node of a service consortium blockchain is obtained. The information storage node is a blockchain node in the service consortium blockchain. The data from the information storage node of the service consortium blockchain is stored in a local database. A service processing request is received from a user device. The service processing request includes an identity of a user of the user device and service information of the user. The local database is searched for service data related to the user based on the identity of the user and the service information of the user. Based on the service data related to the user, service processing information to be used in a service processing operation performed responsive to the service processing request is determined. The service processing operation is completed for the user based on the service processing information.

  • Patent number: 11204894
    Abstract: This specification provides an information read/write method and apparatus based on a blockchain. The information read/write method based on a blockchain includes: receiving a service request from a project member of a project, wherein the service request comprises a service file of the project member and file information of the service file; determining a storage key based on the service file; sending the storage key to an object storage server for permission verification; upon determining that the permission verification succeeded, sending the service file to the object storage server for storage; receiving a file storage identifier returned by the object storage server; generating a service identifier by compressing the file information of the service file; storing the service identifier and the file storage identifier into a blockchain; and obtaining a hash value that is returned from the blockchain.

  • Patent number: 10990563
    Abstract: This specification provides an information read/write method and apparatus based on a blockchain. The information read/write method based on a blockchain includes: receiving a service request from a project member, wherein the service request comprises a to-be-processed service material of the project member; sending a service file in the to-be-processed service material to an object storage server and receiving a file storage identifier returned by the object storage server; processing service information in the to-be-processed service material to generate a service identifier; and writing the service identifier and the file storage identifier into the blockchain, and saving a hash value that is returned by the blockchain and that corresponds to write success information.
