Zusammenfassung:	In an implementation, operation instructions indicating application data to be used for performing one or more operations sent by a first client device are received. The application data is determined based on the operation instructions. One or more second client devices associated with the application data are determined. Operation codes in a trusted execution environment (TEE) associated with the application data to be executed are determined. That the operation codes has been executed for K times based on an indicator is determined. The operation codes are executed in the TEE based on the application data to generate an operation log. An indicator indicating a number of times the operation codes are executed is updated. The operation log and the indicator are sent as an operation record to a database server, the first client device, and the one or more second client devices to be stored.
