upon determining that the first verification failed, receiving a new storage key returned from the object storage server, wherein the new storage key corresponds to a new storage space in the object storage server;

sending the new storage key to the object storage server for a second verification;

upon determining that the second verification succeeded, sending a service file in the to-be-processed service material to the new storage space corresponding to the new storage key in the object storage server and receiving a file storage identifier returned by the object storage server;

processing service information in the to-be-processed service material to generate a service identifier; and

writing the service identifier and the file storage identifier into the blockchain, and saving a hash value that is returned by the blockchain and that corresponds to write success information.

8. The system according to claim 7 , further comprising:

sending, to the object storage server, a request for obtaining the service file in the new storage space corresponding to the new storage key.

9. The system according to claim 8 , wherein the sending a request for obtaining the service file in the new storage space comprises:

sending the new storage key to the object storage server for obtaining a file obtaining permission;

obtaining the file obtaining permission; and

according to the file obtaining permission, extracting the service file corresponding to the file storage identifier in the object storage server.

10. The system according to claim 7 , further comprising:

obtaining identification information of the project member;

authenticating the project member according to the identification information; and

in response to the project member is authenticated, performing the sending the service file in the to-be-processed service material to the object storage server and receiving the file storage identifier returned by the object storage server.

11. The system according to claim 7 , wherein the writing the service identifier and the file storage identifier into the blockchain comprises:

writing the service identifier and the file storage identifier into the blockchain according to a preset storage mode of the blockchain.

12. The system according to claim 7 , wherein the processing service information in the to-be-processed service material to generate a service identifier comprises:

compressing the service information to generate a unique service identifier comprising the compressed service information.

13. A non-transitory computer-readable storage medium for information read/write based on a blockchain, configured with instructions executable by one or more processors to cause the one or more processors to perform operations comprising:
