The two-dimensional code encryption verification information is easy-to-transmit information generated based on the contents of the node data, for example: and extracting keywords in the node data to generate corresponding two-dimensional code encryption verification information. The two-dimension code encryption verification information is used for acquiring node data corresponding to the block chain data query request from the block chain. The node data may be commodity information, business information, user personal data, common data of a plurality of subjects, and the like.
Step S02 publishes the mapping to the blockchain: in this step, the mapping relationship is published to the blockchain. Once the node data on the block chain is generated, the node data cannot be changed, so that the node data cannot be updated on the basis of the original node data, and only the mapping relation between the node data and the two-dimensional code encryption verification information can be issued to the block chain, so that a user can flexibly use the node data on the block chain.
Step S03, when receiving a block chain data query request carrying target verification information sent by a requesting end in a wireless manner, verifies the target verification information according to a mapping relationship established in advance: in this step, when a block chain data query request carrying target verification information and sent by a request end in a wireless manner is received, the target verification information is verified according to a mapping relation established in advance, and whether the content of the block chain data query request is legal or not is mainly verified.

Step S42 sends the information of the verification failure to the requesting end: if the judgment result of the above step S41 is no, the present step is executed. In this step, the information of the verification failure is sent to the request terminal in a wireless manner.
Step S43 is to search for whether node data corresponding to the two-dimensional code encryption verification information exists on the blockchain: if the judgment result of the above step S41 is no, the present step is executed. In this step, whether node data corresponding to the two-dimensional code encryption verification information exists is searched on the blockchain, and if the search result is yes, step S44 is executed; otherwise, step S45 is executed.
Step S44 reads the node data, and feeds back the node data to the requesting end in a wireless manner: if the judgment result of the above step S43 is yes, the present step is executed. In this step, the node data is read and fed back to the requesting end in a wireless manner.
