A system for processing a request in a consortium blockchain, after generating a service on a client device, recording the service on the consortium blockchain through a connected node and receiving, by the client device, a notification message about the consortium blockchain recording the service and including a digest hash of the service, the system comprising: the client device configured to send a request to a plurality of nodes in the consortium blockchain to verify credibility of the consortium blockchain, wherein the request comprises a service location query request and/or a simple payment verification, SPV, request, and the request comprises the digest hash of the service to enable determination of a location of the service in the consortium blockchain through the digest hash of the service; any node configured to receive the request, wherein the any node is a current node and is further configured to determine whether the client device is a user of the current node or a user of another node; wherein the current node is further configured to: in response to determining that the client device is a user of another node, determine a first processing quantity of times for which the current node has processed requests from users of another node, and a second processing quantity of times for which other nodes have processed requests from users of the current node; and perform processing on the request based on the first processing quantity of times and the second processing quantity of times, wherein the processing comprises: deferring processing the request sent by the client device, or transferring the request to other nodes for processing; wherein the client device is further configured to verify the credibility of the consortium blockchain that includes information on the service based on consistency of request results returned by the plurality of nodes. the client device configured to send a request to a plurality of nodes in the consortium blockchain to verify credibility of the consortium blockchain, wherein the request comprises a service location query request and/or a simple payment verification, SPV, request, and the request comprises the digest hash of the service to enable determination of a location of the service in the consortium blockchain through the digest hash of the service; any node configured to receive the request, wherein the any node is a current node and is further configured to determine whether the client device is a user of the current node or a user of another node; wherein the current node is further configured to: in response to determining that the client device is a user of another node, determine a first processing quantity of times for which the current node has processed requests from users of another node, and a second processing quantity of times for which other nodes have processed requests from users of the current node; and perform processing on the request based on the first processing quantity of times and the second processing quantity of times, wherein the processing comprises: deferring processing the request sent by the client device, or transferring the request to other nodes for processing; in response to determining that the client device is a user of another node, determine a first processing quantity of times for which the current node has processed requests from users of another node, and a second processing quantity of times for which other nodes have processed requests from users of the current node; and perform processing on the request based on the first processing quantity of times and the second processing quantity of times, wherein the processing comprises: deferring processing the request sent by the client device, or transferring the request to other nodes for processing; wherein the client device is further configured to verify the credibility of the consortium blockchain that includes information on the service based on consistency of request results returned by the plurality of nodes.
