Service processing method and apparatus based on blockchain system, medium and electronic device

A service processing apparatus connected to a service processing node subnetwork and a service participant system in a blockchain system, the service processing node subnetwork comprising one or more service processing nodes that are deployed in a distributed manner to form a blockchain network, the service processing apparatus comprising:

• at least one memory storing computer program code;
• and
• at least one processor configured to access the at least one memory and operate as instructed by the computer program code, the computer program code comprising:
• processing code configured to cause at least one processor to obtain authentication information of a service participant;
• generation code configured to cause at least one processor to determine whether data in the authentication information of the service participant is updated, and generate, based on the data in the authentication information of the service participant being updated, a notification message according to the updated data;
• and
• transmission code configured to cause at least one processor to transmit the notification message to the service processing node subnetwork, the notification message instructing the one or more service processing nodes in the service processing node subnetwork to process a service request according to updated authentication information of the service participant.

A non-transitory computer-readable storage medium storing at least one computer program code, the at least one computer program code, when executed by at least one processor of a processing node in a service processing node subnetwork of a blockchain network causes at least the processor to:

• obtain authentication information of a service participant;
• determine whether data in the authentication information of the service participant is updated;
• generate, based on the data in the authentication information of the service participant being updated, a notification message according to the updated data;
• and
• transmit the notification message to a service processing node subnetwork, the notification message instructing one or more service processing nodes in the service processing node subnetwork to process a service request according to updated authentication information of the service participant,
• wherein the processing node is one of one or more processing nodes that are deployed in a distributed manner to form the blockchain network.
