Abstract

An example operation may include one or more of receiving a plurality of state representations of a plurality of off-chain systems for performing a multi-party process via a blockchain, wherein each state representation identifies send and receive events of a respective off-chain system, removing one or more events from a state representation of an off-chain system to generate a reduced state representation, generating executable chaincode for the blockchain based on the plurality of state representations including the reduced state representation, and storing the generated chaincode via a blockchain node of the blockchain.

Claims

1. A computing system comprising:

processor configured to generate a plurality of state representations based on a communication model between a plurality of off-chain systems of a multi-party process in which a blockchain is an intermediary, wherein each state representation models send and receive communications of a respective off-chain system,

wherein the processor is further configured to remove one or more communications from a state representation of an off-chain system to generate a reduced state representation, generate executable chaincode for the blockchain based on the plurality of state representations which include the reduced state representation, and store the generated chaincode via the storage.

2. The computing system of claim 1, wherein the processor is further configured to transform an overall process description of the multi-party process which includes modeled process steps between the plurality of off-chain systems and the blockchain into the plurality of state representations comprising individual modeled communication charts for the plurality of off-chain systems.

3. The computing system of claim 2, wherein the blockchain is an intermediate communication system between the plurality of off-chain systems within the multi-party process.

4. The computing system of claim 1, further comprising a network interface configured to receive a blockchain state representation that models send, receive, and storage events of the blockchain, and the processor is further configured to generate the chaincode based on the blockchain state representation.

5. The computing system of claim 1, wherein the processor is configured to remove the one or more communications based on an action performed by the off-chain system in association with the one or more communications.

6. The computing system of claim 1, wherein the processor is configured to remove a receive communication from among a group of consecutive receive communications within the state representation of the off-chain system.

7. The computing system of claim 1, wherein the processor is configured to remove a plurality of receive communications of the off-chain system while the processor is configured to retain all send communications of the off-chain system.

8. The computing system of claim 1, wherein the state representation comprises a state diagram in which communications are modeled as nodes in the diagram, and the nodes are arranged based on a sequence in which the communications occur within the multi-party process.

21. The computing system of claim 1, wherein the processor removes the one or more communications based on a communication activity of the off-chain system associated with the one or more communications.

9. A method comprising:

generating a plurality of state representations of a based on a communication model between a plurality of off-chain systems of a multi-party process in which a blockchain is an intermediary, wherein each state representation models send and receive communications of a respective off-chain system;

removing one or more communications from a state representation of an off-chain system to generate a reduced state representation;

generating executable chaincode for the blockchain based on the plurality of state representations including the reduced state representation; and

storing the generated chaincode via a blockchain node of the blockchain.

10. The method of claim 9, further comprising transforming an overall process description of the multi-party process comprising modeled process steps between the plurality of off-chain systems and the blockchain into the plurality of state representations comprising individual modeled communication charts for the plurality of off-chain systems.

11. The method of claim 10, wherein the blockchain is an intermediate communication system between the plurality of off-chain systems within the multi-party process.

12. The method of claim 9, wherein the receiving further comprising receiving a blockchain state representation that models send, receive, and storage events of the blockchain, and the generating of the chaincode is further performed based on the blockchain state representation.

13. The method of claim 9, wherein the removing comprises removing the one or more communications based on an action performed by the off-chain system during the one or more communications.

14. The method of claim 9, wherein the removing comprises removing a receive communications from among a group of consecutive receive communications within the state representation of the off-chain system.

15. The method of claim 9, wherein the removing comprises removing a plurality of receive communications of the off-chain system while retaining all sending communications of the off-chain system.

16. The method of claim 9, wherein the state representation comprises a state diagram in which communications are modeled as nodes in the diagram, and the nodes are arranged based on a sequence in which the corresponding communications occur within the multi-party process.

17. A non-transitory computer readable medium comprising instructions that when read by a processor cause the processor to perform a method comprising:

generating a plurality of state representations of a based on a communication model between a plurality of off-chain systems of a multi-party process in which a blockchain is an intermediary, wherein each state representation models send and receive communications of a respective off-chain system;

removing one or more communications from a state representation of an off-chain system to generate a reduced state representation;

generating executable chaincode for the blockchain based on the plurality of state representations including the reduced state representation; and
