And S204, the second client sends the knowledge sharing data query request to the block chain node, wherein the knowledge sharing data query request comprises the public key of the second client.
At this time, the user corresponding to the second client may query the knowledge sharing data after seeing the knowledge sharing 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.
