Method and device for processing service request

A method for processing a service request, comprising:

• receiving, by a consensus node, a service request corresponding to a target service, wherein the service request comprises service data of the target service and a digest of the service data;
• performing, by the consensus node, consensus verification on the service request based on the service data and the digest;
• instructing, by the consensus node, each non-consensus node to store the digest in a blockchain in response to determining that the service request passes the consensus verification;
• and
• sending, by the consensus node, the service data to at least one service node so that the service node stores the service data in a private database corresponding to the service node;
• or
• sending, by the consensus node, a storage instruction to at least one service node so that the service node stores the service data in a private database corresponding to the service node;
• or
• sending, by the consensus node, an acknowledgement instruction to a service node initiating the target service so that the service node stores the service data in a private database corresponding to the service node;
• and sending the service data to another service node so that the other service node stores the service data in a private database corresponding to the other service node, wherein the service node is a blockchain node participating in the target service.

An apparatus for processing a service request, comprising:

• a receiving module, configured to receive a service request corresponding to a target service and received by a consensus node, wherein the service request comprises service data of the target service and a digest of the service data;
• a consensus verification module, configured to perform consensus verification on the service request based on the service data and the digest;
• a storage module, configured to store the digest in a blockchain in response to determining that the service request passes the consensus verification;
• and
• a sending module, configured to:
• in response to determining that the service request passes the consensus verification, send the service data to at least one service node so that the service node stores the service data in a private database corresponding to the service node;
• or send a storage instruction to at least one service node so that the service node stores the service data in a private database corresponding to the service node;
• or send an acknowledgement instruction to a service node initiating the target service so that the service node stores the service data in a private database corresponding to the service node, and send the service data to another service node so that the other service node stores the service data in a private database corresponding to the other service node, wherein the service node is a blockchain node participating in the target service.
