Embodiment approach
[0058] The first implementation mode: if image 3 as shown, image 3 It is a schematic flowchart of encryption in a blockchain-based data processing method provided according to an exemplary embodiment of the present disclosure, the smart contract code and the first blockchain node executing the smart contract code The resulting data encryption may include the following steps.
[0059] In step S241, the secret key is randomly generated, and the secret key randomly generated this time is obtained.
[0060] In step S242, encrypt the smart contract code and the data generated by the first block chain node executing the smart contract code using the randomly generated secret key this time.
[0061] In step S243, the secret key randomly generated this time is updated into the digital envelope of the management contract.
[0062] Using the first implementation mode, before encrypting the smart contract code and the data generated by the first blockchain node executing the smart c...
