A method for service processing, the method comprising: receiving, by a first server of a first plurality of servers included in a first blockchain node of a consensus network, a service request sent by a client, wherein the first blockchain node comprises service memory, wherein the first plurality of servers shares node configuration information within the first blockchain node, wherein an operation performed by a server from the first plurality of servers is considered as performed by the first blockchain node, wherein the first server is registered with a registration center as available to service requests from the client, and wherein the registration center is configured to manage addresses of servers in corresponding blockchain nodes of the consensus network, wherein each blockchain node in the consensus network includes a corresponding plurality of servers; storing, by the first server, the service request in the service memory comprised in the first blockchain node; obtaining, by the first plurality of servers in the first blockchain node from the registration center, a plurality of addresses corresponding to a second plurality of servers of a second blockchain node of the consensus network, wherein the registration center manages the plurality of addresses of the second plurality of servers of the second blockchain node; and sending, by the first server and using the obtained addresses of the second plurality of servers in the second blockchain node, the service request to the second blockchain node in the consensus network, so that second blockchain node stores the service request in a service memory comprised in the second blockchain node after receiving the service request, wherein the second blockchain node comprises the second plurality of servers and at least one service memory. receiving, by a first server of a first plurality of servers included in a first blockchain node of a consensus network, a service request sent by a client, wherein the first blockchain node comprises service memory, wherein the first plurality of servers shares node configuration information within the first blockchain node, wherein an operation performed by a server from the first plurality of servers is considered as performed by the first blockchain node, wherein the first server is registered with a registration center as available to service requests from the client, and wherein the registration center is configured to manage addresses of servers in corresponding blockchain nodes of the consensus network, wherein each blockchain node in the consensus network includes a corresponding plurality of servers; storing, by the first server, the service request in the service memory comprised in the first blockchain node; obtaining, by the first plurality of servers in the first blockchain node from the registration center, a plurality of addresses corresponding to a second plurality of servers of a second blockchain node of the consensus network, wherein the registration center manages the plurality of addresses of the second plurality of servers of the second blockchain node; and sending, by the first server and using the obtained addresses of the second plurality of servers in the second blockchain node, the service request to the second blockchain node in the consensus network, so that second blockchain node stores the service request in a service memory comprised in the second blockchain node after receiving the service request, wherein the second blockchain node comprises the second plurality of servers and at least one service memory.
