Multi-blockchain network data processing

1. A computer-implemented method, comprising:

obtaining a data processing request at a blockchain node that is operating as a blockchain node in both a public blockchain network and an alliance-specific blockchain network, the data processing request containing an identifier used to identify the public blockchain network or the alliance-specific blockchain network as a blockchain network to which the data processing request belongs, wherein the blockchain node comprises a ledger for the public blockchain network and a ledger for the alliance-specific blockchain network;

extracting the identifier from the data processing request; and

executing, based on the identifier, corresponding processing logic associated with the data processing request.

2. The computer-implemented method of claim 1 , further comprising generating the identifier based on a network identifier of the blockchain network to which the data processing request belongs.

3. The computer-implemented method of claim 1 , wherein the data processing request comprises a data storage request message.

4. The computer-implemented method of claim 1 , wherein the data processing request comprises a data read request message.

5. The computer-implemented method of claim 4 , wherein executing corresponding processing logic associated with the data processing request comprises reading blockchain data from a blockchain storage area corresponding to the identifier.

6. The computer-implemented method of claim 1 , wherein the data processing request comprises a node communication message.

7. The computer-implemented method of claim 6 , further comprising, based on the identifier, exchanging the node communication message in the blockchain network to which the data processing request belongs.

8. A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:

obtaining a data processing request at a blockchain node that is operating as a blockchain node in both a public blockchain network and an alliance-specific blockchain network, the data processing request containing an identifier used to identify the public blockchain network or the alliance-specific blockchain network as a blockchain network to which the data processing request belongs, wherein the blockchain node comprises a ledger for the public blockchain network and a ledger for the alliance-specific blockchain network;

extracting the identifier from the data processing request; and

executing, based on the identifier, corresponding processing logic associated with the data processing request.

9. The non-transitory, computer-readable medium of claim 8 , wherein the operations comprise generating the identifier based on a network identifier of the blockchain network to which the data processing request belongs.

10. The non-transitory, computer-readable medium of claim 8 , wherein the data processing request comprises a data storage request message.

11. The non-transitory, computer-readable medium of claim 8 , wherein the data processing request comprises a data read request message.

12. The non-transitory, computer-readable medium of claim 11 , wherein executing corresponding processing logic associated with the data processing request comprises reading blockchain data from a blockchain storage area corresponding to the identifier.

13. The non-transitory, computer-readable medium of claim 8 , wherein the data processing request comprises a node communication message.

14. The non-transitory, computer-readable medium of claim 13 , wherein the operations comprise, based on the identifier, exchanging the node communication message in the blockchain network to which the data processing request belongs.

15. A computer-implemented system, comprising:

one or more computers; and

one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:

obtaining a data processing request at a blockchain node that is operating as a blockchain node in both a public blockchain network and an alliance-specific blockchain network, the data processing request containing an identifier used to identify the public blockchain network or the alliance-specific blockchain network as a blockchain network to which the data processing request belongs, wherein the blockchain node comprises a ledger for the public blockchain network and a ledger for the alliance-specific blockchain network;

extracting the identifier from the data processing request; and

executing, based on the identifier, corresponding processing logic associated with the data processing request.

16. The computer-implemented system of claim 15 , wherein the operations comprise generating the identifier based on a network identifier of the blockchain network to which the data processing request belongs.

17. The computer-implemented system of claim 15 , wherein the data processing request comprises a data storage request message.

18. The computer-implemented system of claim 15 , wherein the data processing request comprises a data read request message.

19. The computer-implemented system of claim 18 , wherein executing corresponding processing logic associated with the data processing request comprises reading blockchain data from a blockchain storage area corresponding to the identifier.

20. The computer-implemented system of claim 15 , wherein the data processing request comprises a node communication message.

21. The computer-implemented system of claim 20 , wherein the operations comprise, based on the identifier, exchanging the node communication message in the blockchain network to which the data processing request belongs.
