At this time, the user corresponding to the second client may query the community data after seeing the community 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 S205, triggering a check intelligent contract on the block chain, checking the identity of the second client by the check intelligent contract, encrypting the community data by using the public key of the second client after the check is passed, and executing the uplink process on the community data encrypted by using the public key of the second client.
After the verification is passed, executing the next flow; the check fails and the process terminates.
And S206, the block chain node sends a community data query response to the second client.
And S207, the second client sends a community data query request to the blockchain node.
And S208, the block nodes send community data query responses to the second client, wherein the community data query responses comprise community data encrypted by the public key of the second client.
