Transaction processing in a service blockchain

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, wherein the service blockchain is interlinked with an asset service blockchain so that the service blockchain and the asset service blockchain can read and authenticate data from each other, and the asset service blockchain is further interlinked with a plurality of asset-service-institution servers through an Oracle machine;
• based on receiving the target transaction, (i) triggering execution of a target service and (ii) determining a target asset-service-institution server corresponding to the target service from the plurality of asset-service-institution servers;
• invoking, by the node device and through the Oracle machine, an asset exchange service deployed on the target asset-service-institution server, to complete asset exchange processing between service accounts related to the target transaction;
• and
• obtaining, by the node device and through the Oracle machine, an asset exchange credential between the service accounts related to the target transaction.

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, cause the one or more computers 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, wherein the service blockchain is interlinked with an asset service blockchain so that the service blockchain and the asset service blockchain can read and authenticate data from each other, and the asset service blockchain is further interlinked with a plurality of asset-service-institution servers through an Oracle machine;
• based on receiving the target transaction, (i) triggering execution of a target service and (ii) determining a target asset-service-institution server corresponding to the target service from the plurality of asset-service-institution servers;
• invoking, by the node device and through the Oracle machine, an asset exchange service deployed on the target asset-service-institution server, to complete asset exchange processing between service accounts related to the target transaction;
• and
• obtaining, by the node device and through the Oracle machine, an asset exchange credential between the service accounts related to the target transaction.
