Abstract
One or more implementations of the present specification provide a data processing method and apparatus for a blockchain member node, where the blockchain member node includes a plurality of service servers, and at least one authentication module runs on each service server; and a public key of an authentication module of the at least one authentication module is authenticated by the blockchain. The method includes: obtaining, by a downstream service server of the plurality of service servers, a first service processing result and a first digital signature that are generated by an upstream service server of the plurality of service servers; verifying the first digital signature based on a public key of an authentication module running on the upstream service server; performing service processing based on the first service processing result after the verification succeeds, thereby generating a second service processing result; and generating a second digital signature by performing digital signing based on at least the second service processing result using an authentication module running on the downstream service server.
