Method and apparatus for generating blockchain transaction

A computer device, comprising a processor and a memory, the memory having executable instructions stored thereon, the executable instructions, when executed by the processor, enabling the processor to implement acts including:

• obtaining, by a second service server, a first service processing result and a first digital signature that are generated by a first service server, the first digital signature being made by a first authentication module based on at least the first service processing result, the first service processing result being a ciphertext encrypted using a first public key of the first authentication module;
• verifying the first digital signature using the first public key of the first authentication module;
• obtaining a plaintext of the first service processing result by decrypting the first service processing result using a first private key of the first authentication module;
• generating a second service processing result by performing service processing on the plaintext of the first service processing result;
• and
• encrypting the second service processing result.

A non-transitory computer readable storage medium storing executable instructions thereon, which when executed by a processor enable the processor to implement operations including:

• obtaining, by a second service server, a first service processing result and a first digital signature that are generated by a first service server, the first digital signature being made by a first authentication module based on at least the first service processing result, the first service processing result being a ciphertext encrypted using a first public key of the first authentication module;
• verifying the first digital signature using the first public key of the first authentication module;
• obtaining a plaintext of the first service processing result by decrypting the first service processing result using a first private key of the first authentication module;
• generating a second service processing result by performing service processing on the plaintext of the first service processing result;
• and
• encrypting the second service processing result.
