Each contract participant sends the temporary public key to other contract participants. First signature data is generated by each contract participant signing data information including the target contract and temporary public keys of the contract participants by using the temporary private key. A contract participant encrypts predetermined contract information by using a regulatory key of a regulator to generate an encrypted contract signed by each contract participant using the temporary private key, to generate second signature data. Creation data is determined and submitted to the blockchain for storage, where the creation data includes the temporary public key and the second signature data of each contract participant and the encrypted contract.
