Abstract:
Techniques for processing blockchain data are described. Each contract participant of a plurality of contract participants in a blockchain generates, for a target contract, a paired temporary public key and private key generated based on an asymmetric encryption algorithm. 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.

Claim (Index 1):
A computer-implemented method, comprising:\n generating, by each contract participant of a plurality of contract participants in a blockchain, temporary keys for a target contract, wherein the temporary keys comprise a temporary public key and a temporary private key that are paired with each other and are generated based on an asymmetric encryption algorithm, the temporary keys generated by each contract participant being different from temporary keys generated by other contract participants in the plurality of contract participants; sending, by each contract participant of the plurality of contract participants, the temporary public key to other contract participants of the plurality of contract participants; signing, by each contract participant of the plurality of contract participants, data information that comprises the target contract and temporary public keys of the plurality of contract participants by using [[the]] a corresponding temporary private key generated by the contract participant signing the data information, to generate a respective first signature data corresponding to the contract participant signing the data information; encrypting, by a contract participant of the plurality of contract participants, predetermined contract information by using a regulatory key of a regulator to generate an encrypted contract, wherein the predetermined contract information comprises the target contract, the temporary public key of each contract participant, and the first signature data of each contract participant; determining creation data comprising the encrypted contract; and submitting the creation data to the blockchain for storage.
