The content for being related to privacy is encrypted；It is also possible to user not encrypt the knowledge question data.
In addition, the knowledge question data include being divided into two attribute, relating attribute and dereferenced attribute.Such as: Yong Huzhi
Know the question and answer operating time, belongs to dereferenced attribute, the knowledge question operating time of every user may be stored on block chain；
Such as: the displaying number of knowledge question data, is exactly relating attribute, includes that knowledge question is shown in the data format of knowledge question
Number, as long as there is other users to see the knowledge question data from respective terminal, which shows the attribute of number
Value can be superimposed automatically.
The knowledge question data include the data asked and the data answered, that is, knowledge puts question to data and knowledge to answer number
According to；It includes that knowledge puts question to time, knowledge subject of question and knowledge to put question to user that knowledge, which puts question to data,；Knowledge replies data
Knowledge response time, knowledge answer content and knowledge answer user.In addition, further including the same problem, the number number of answer
According to.
S202, the first client send knowledge question data cochain and request to give block chain node.
S203, triggers the verification intelligence contract on block chain, which carries out the identity of the first client
Verification, executes the cochain process of the knowledge question data.
The verification refer to judge first client whether be the knowledge question platform user, the only knowledge question is flat
The user of platform, which can just have permission, carries out cochain for the knowledge question data.
It should be noted that upper chain process is the conventional process of this field, without being described in detail.Such as: in workload
It proves to be packaged data under PoW common recognition mode, verify, the block chain node for getting book keeping operation power can be by the packing block
It is placed on next block of current block, as new block cochain.
S204, block chain node send knowledge question data cochain and respond to the first client.
S205, the second client send knowledge question data inquiry request and give block chain node, the knowledge question data
Inquiry request includes the second client public key.
At this point, the corresponding user of the second client can be after seeing the knowledge question data, to the knowledge question number
According to being inquired.The first client and the second client are all to be equipped with the terminal of decentralization application software to set in the application
It is standby, row information directly can be clicked through with the block chain link on block chain interact.
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 knowledge question data inquiry request to the first client, this is known
Knowing question and answer data inquiry request includes the second client public key.
S208, the first client encrypt the knowledge question data with second client public key.
S209, the first client send knowledge question data query and respond to the block chain node, the knowledge question data
Inquiry response includes the knowledge question data of the second client public key encryption.
S210 triggers the verification intelligence contract on block chain, identity of the verification intelligence contract to first client
It is verified, and the knowledge question data of second client public key encryption is executed into cochain process.
S211, the block chain node send knowledge question data query and respond to the second client.
S212, the second client send knowledge question data inquiry request and give block chain node.
S213, the block chain node send the knowledge question data query and respond to second client, the knowledge question
Data query response includes the knowledge question data of the second client public key encryption.
S214, the second client are solved with the knowledge question data that own private key encrypts second client public key
It is close, obtain the knowledge question data.
The application can allow the data cochain of knowledge question, and the cochain process is open and clear, same knowledge question platform
Any user can check the knowledge question data；It ensure that the authenticity of knowledge question data.Also, user can basis
The hobby of oneself encrypt or do not encrypt to knowledge question data, 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 allowing knowledge question data more to disclose can
Letter；Rather than existing client and the server of centralization interact.
