And S106, triggering a verification intelligent contract, verifying the identity of the first client by the verification intelligent contract, and executing a chain linking process on the approval data encrypted by the public key of the second client after the verification is passed.
In one example, the public key of the second client is sent to the first client for the block link node, specifically: the blockchain node receives a query request sent by the first client, and queries whether the compliment data is checked and the identity of a viewer; and the block chain node sends a query response to the first client, wherein the query response comprises the public key of the second client.
In one example, the like data is operation data of the like platform of the first client, and comprises a number of like times, a like time, comment content and a like type.

It should be noted that the uplink process is a conventional process in the art and will not be described in detail. For example: and under the workload certification PoW common mode, packaging and verifying the data, wherein the block link point of the account right can place the packaged block in the next block of the current block as a new block uplink.
S204, the block link node sends a link up response to the first ue.
And S205, the second client sends a query request to the blockchain node, wherein the query request is used for querying the approval data of the first client.
At this time, the user corresponding to the second client may query the approval data after seeing the approval data. In the application, the first client and the second client are both terminal devices provided with decentralized application software, and can directly perform information interaction with the blockchain nodes on the blockchain.
And S206, triggering a check intelligent contract on the block chain, wherein the check intelligent contract checks the identity of the second client and checks whether the second client is a user of the compliment platform.
After the verification is passed, executing the next flow; the check fails and the process terminates.
S207, the block node sends a check response to the second client.
S208, the first client sends a query request to the block chain node, the query request queries whether the approval data is checked, and if the approval data is checked, the public key of the viewer is acquired.
S209, the block node sends a query response to the first client, where the query response includes the public key of the second client.
S210, the first ue sends an inquiry uplink request to the blockchain node, where the inquiry uplink request includes the approval data encrypted by the public key of the second ue.
And S211, triggering a check intelligent contract on the block chain, checking the identity of the first client by the check intelligent contract, and executing a cochain process on the encrypted praise data of the public key of the second client after the check is passed.
S212, the block node sends a search uplink response to the first ue.
S213, the second client sends the approval data query request to the blockchain node.
And S214, the block link node sends an approval data response to the second client, wherein the approval data response comprises the approval data encrypted by the public key of the second client.
S215, the second client decrypts the praise data encrypted by the public key of the second client by using its own private key, so as to obtain the praise data.
The method and the device have the advantages that the praise data can be linked, the link process is public and transparent, and any user of the same praise platform can check the praise data; the authenticity of the praise data is guaranteed. In addition, the user can encrypt or not encrypt the praise data according to the preference of the user, and the user experience is improved.
It should be noted that, in the present application, a client directly performs information interaction with a node of a block chain, and the block chain node directly stores information on the block chain without a centralized server, so that the like data is more open and reliable; rather than the existing client interacting with a centralized server.
