In one example, the evaluation data are operand of the corresponding user of first client in evaluation platform
According to, including evaluation number, evaluation time, evaluation content and evaluation type.
In one example, the first client own public key is to the evaluation data encryption, specifically: described
One client carries out the encryption of preset ratio with own public key to the evaluation data.
In one example, the evaluation data include relating attribute and dereferenced attribute；Wherein, the evaluation data are closed
Attribute attribute value is superimposed automatically.
In above-mentioned example, operator of first client as evaluation data, the second client is looked into as evaluation data
Inquiry person；For some specific evaluation platform, every user either evaluation data operator, be also possible to evaluate data
Inquiry.
Below by taking Fig. 2 as an example, the cochain method flow for the evaluation data of the application being applied on block chain is said
Bright, this method includes S201-S209.
S201, the first client send evaluation data cochain and request to give block chain node, in evaluation data cochain request
Including the first client public key.
S202, triggers the verification intelligence contract on block chain, the verification intelligence contract to the identity of first client into
Row verification, and the evaluation data are encrypted with first client public key, and commenting first client public key encryption
Valence mumber is according to execution cochain process.
