7. The apparatus of claim 6, wherein the contract signing unit is specifically configured to:
after the data processing result demander pays a preset cost, triggering the execution contract to start execution;
after the execution contract starts to be executed, a target algorithm provider corresponding to the second block chain identifier encapsulates an executable file of a target algorithm into a binary stream, encrypts the binary stream to generate an encrypted target algorithm, and issues the encrypted target algorithm to the block chain;
the target computing power provider corresponding to the third block chain identifier obtains the encrypted target algorithm from the block chain, decrypts the encrypted target algorithm to obtain a binary stream, and restores the binary stream into an executable file of the target algorithm;
the target computing power provider acquires target data from a target data provider corresponding to the first blockchain identifier;
and the target computing power provider operates the target algorithm under the computing power environment of the target computing power provider to process the target data to generate a data processing result, encrypts the data processing result to generate an encrypted data processing result, and issues the encrypted data processing result to the block chain.
8. The apparatus according to claim 7, wherein the result obtaining unit is specifically configured to:
monitoring whether the data processing result is uplink or not;
downloading the encrypted data processing result from the block chain after monitoring the uplink of the data processing result;
and decrypting the encrypted data processing result to obtain a final data processing result.
9. A storage medium storing a program to implement the steps of the block chain based data processing method according to any one of claims 1 to 4.
10. An electronic device, comprising:
a memory and a processor;
the memory stores a program adapted to be executed by the processor to implement the steps of the blockchain-based data processing method of any one of claims 1 to 4.
