Abstract

Implementations of this specification provide a method and an apparatus for transaction processing in a service blockchain. An example method performed by a node device in the service blockchain includes receiving a target transaction, from a service system interlinked with the service blockchain; in response to receiving the target transaction, (i) triggering execution of a target service and (ii) determining a target asset blockchain corresponding to the target service from a plurality of asset blockchains interlinked with the service blockchain through a cross-chain relay; invoking, through the cross-chain relay, an asset exchange service deployed on the target asset blockchain, to complete asset exchange processing between transaction accounts related to the target transaction; obtaining, through the cross-chain relay, an asset exchange credential between the transaction accounts related to the target transaction; and after obtaining the asset exchange credential, performing further transaction processing on the target service.

First claim

What is claimed is:

1 . A computer-implemented method comprising:
receiving a target transaction, by a node device in a service blockchain and from a service system interlinked with the service blockchain, the service system having posted the target transaction to the service blockchain; in response to receiving the target transaction, (i) triggering execution of a target service and (ii) determining a target asset blockchain corresponding to the target service from a plurality of asset blockchains interlinked with the service blockchain through a cross-chain relay; invoking, by the node device and through the cross-chain relay, an asset exchange service deployed on the target asset blockchain, to complete asset exchange processing between transaction accounts related to the target transaction; obtaining, by the node device and through the cross-chain relay, an asset exchange credential between the transaction accounts related to the target transaction; and after obtaining the asset exchange credential, performing further transaction processing on the target service.

2 . The computer-implemented method according to claim 1 , further comprising:
in response to receiving the target transaction, invoking a cross-chain processing logic in a first smart contract deployed on the service blockchain.

3 . The computer-implemented method according to claim 2 , further comprising:
invoking, by the node device and through the cross-chain relay, an asset exchange service logic in a second smart contract deployed on the target asset blockchain, to complete asset exchange processing between transaction accounts related to the target transaction; and obtaining, by the node device and through the cross-chain relay, the asset exchange credential posted by the second smart contract to the target asset blockchain for storage after the asset exchange processing is completed.

4 . The computer-implemented method according to claim 2 , wherein performing further transaction processing on the target service comprises:
invoking a transaction processing logic in the first smart contract to perform further transaction processing on the target service; and posting a transaction processing result to the service blockchain for storage.

5 . The computer-implemented method according to claim 1 , wherein performing further transaction processing on the target service comprises:
posting the asset exchange credential to the service blockchain for storage; and upon monitoring the asset exchange credential that has been posted to the service blockchain for storage, posting a transaction processing result to the service blockchain for storage.

6 . The computer-implemented method according to claim 1 , wherein
the service blockchain is interlinked with an asset service chain through the cross-chain relay, and the asset service chain is further interlinked with the plurality of asset blockchains through the cross-chain relay.

7 . The computer-implemented method according to claim 1 , wherein
the service blockchain is interlinked with an asset service chain through the cross-chain relay, and the asset service chain is further interlinked with a server of an asset service institution through an Oracle machine.

8 . The computer-implemented method according to claim 1 , wherein
the service blockchain is interlinked with a server of an asset service institution through an Oracle machine, wherein the server of the asset service institution deploys the asset exchange service.

9 . 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 operations comprising: receiving a target transaction, by a node device in a service blockchain and from a service system interlinked with the service blockchain, the service system having posted the target transaction to the service blockchain; in response to receiving the target transaction, (i) triggering execution of a target service and (ii) determining a target asset blockchain corresponding to the target service from a plurality of asset blockchains interlinked with the service blockchain through a cross-chain relay; invoking, by the node device and through the cross-chain relay, an asset exchange service deployed on the target asset blockchain, to complete asset exchange processing between transaction accounts related to the target transaction; obtaining, by the node device and through the cross-chain relay, an asset exchange credential between the transaction accounts related to the target transaction; and after obtaining the asset exchange credential, performing further transaction processing on the target service.

10 . The system according to claim 9 , the operations further comprising:
in response to receiving the target transaction, invoking a cross-chain processing logic in a first smart contract deployed on the service blockchain.

11 . The system according to claim 10 , the operations further comprising:
invoking, by the node device and through the cross-chain relay, an asset exchange service logic in a second smart contract deployed on the target asset blockchain, to complete asset exchange processing between transaction accounts related to the target transaction; and obtaining, by the node device and through the cross-chain relay, the asset exchange credential posted by the second smart contract to the target asset blockchain for storage after the asset exchange processing is completed.

12 . The system according to claim 10 , wherein performing further transaction processing on the target service comprises:
invoking a transaction processing logic in the first smart contract to perform further transaction processing on the target service; and posting a transaction processing result to the service blockchain for storage.

13 . The system according to claim 9 , wherein performing further transaction processing on the target service comprises:
posting the asset exchange credential to the service blockchain for storage; and upon monitoring the asset exchange credential that has been posted to the service blockchain for storage, posting a transaction processing result to the service blockchain for storage.

14 . The system according to claim 9 , wherein
the service blockchain is interlinked with an asset service chain through the cross-chain relay, and the asset service chain is further interlinked with the plurality of asset blockchains through the cross-chain relay.

15 . The system according to claim 9 , wherein
the service blockchain is interlinked with an asset service chain through the cross-chain relay, and the asset service chain is further interlinked with a server of an asset service institution through an Oracle machine.

16 . The system according to claim 9 , wherein
the service blockchain is interlinked with a server of an asset service institution through an Oracle machine, wherein the server of the asset service institution deploys the asset exchange service.

17 . A non-transitory, computer-readable medium storing one or more instructions executable by a computer system to perform operations comprising:
receiving a target transaction, by a node device in a service blockchain and from a service system interlinked with the service blockchain, the service system having posted the target transaction to the service blockchain; in respo
