It askes.The first client and the second client are all the terminal devices for being equipped with decentralization application software in the application, all may be used
It is interacted with directly clicking through row information with the block chain link on block chain.
S206, triggers the verification intelligence contract on block chain, which carries out the identity of the second client
Verification.
After verification passes through, process is performed the next step；Verification does not pass through, Flow ends.
S207, after verification passes through, which sends evaluation data inquiry request to the first client, the review number
It is investigated that asking request includes the second client public key.
S208, the first client encrypt the evaluation data with second client public key.
S209, the first client send evaluation data query and respond to the block chain node, evaluation data query response
Evaluation data including the encryption of the second client public key.
S210 triggers the verification intelligence contract on block chain, identity of the verification intelligence contract to first client
It is verified, and the evaluation data of second client public key encryption is executed into cochain process.
S211, the block chain node send evaluation data query and respond to the second client.
S212, the second client send evaluation data inquiry request and give block chain node.
S213, the block chain node send the evaluation data query and respond to second client, the evaluation data query
Response includes the evaluation data of the second client public key encryption.
S214, the second client are decrypted with the evaluation data that own private key encrypts second client public key, are obtained
To the evaluation data.
The application can allow the data cochain of evaluation, and the cochain process is open and clear, any user of same evaluation platform
It can check the evaluation data；It ensure that the authenticity of evaluation data.Also, user can be according to oneself hobby, to commenting
Valence mumber is encrypted according to carrying out or is not encrypted, and improves user experience.
It should be noted that client is directly to carry out the interaction of information, block chain with the node of block chain in the application
Information is stored directly on block chain by node, not the server of centralization, so that it is credible to allow evaluation data more to disclose；And
It is not that the server of existing client and centralization interacts.
As shown in figure 3, a kind of evaluation data cochain equipment for applying intelligent contract, the equipment are block chain node, institute
