In addition, the sequence of steps in each method embodiment described below is only an example and is not strictly limited.
Fig. 1 is a flowchart of a block chain information query method according to an embodiment of the present invention, which may be executed by a terminal device on an owner side of a target object. As shown in fig. 1, the method comprises the steps of:
101. and storing the characteristic information of the target object into the block chain.
102. Index information corresponding to the feature information is acquired.
103. And generating an identification code corresponding to the index information.
104. And associating the identification code with the target object so that the query equipment can acquire the index information for querying the characteristic information by identifying the identification code.
In the embodiment of the present invention, the target object may be, for example, a certain product, and the characteristic information may be product detail information. For example, the product is an agricultural product, and the characteristic information is information such as a production place and a production date of the agricultural product. For another example, the target object may be a certain enterprise, and the characteristic information may be related information of the assets and the generated products of the enterprise.
Assuming that the terminal device of the owner of the target object is a, in an optional embodiment, on one hand, the terminal device a may store the feature information of the target object in a block chain, that is, in a certain block in the block chain, and on the other hand, may also generate index information corresponding to the feature information in the process of storing the feature information into the block chain, and at this time, the index information generated by the terminal device a may also be stored into the block chain together, so that each subsequent related user may query the feature information of the target object based on the index information.
It should be noted that the index information may be obtained by performing a certain processing on the feature information, for example, may be some kind of information extracted from the feature information, or may be a result obtained by performing a certain operation on the feature information, for example, a hash operation.
In combination with the actual query requirement, optionally, the index information may be identity information corresponding to the target object, so that all feature information of the same target object may be queried based on the identity information, where the identity information of the target object may be, for example, a wallet address corresponding to the target object, that is, the index information may include the wallet address corresponding to the target object.
Alternatively, the index information may also be corresponding to a piece of feature information currently stored, for example, a hash value obtained by performing a hash operation on the feature information, so that a specific piece of feature information may be queried based on the hash value. That is, the acquiring of the index information corresponding to the feature information may be implemented as: and performing hash operation on the characteristic information to obtain a hash value serving as index information, and storing the characteristic information of the target object and the hash value into the block chain.
In an alternative embodiment, still assuming that the terminal device of the owner of the target object is a, when the index information is generated by the terminal device a, the process of the terminal device a storing the feature information of the target object and the index information into the block chain may be: the terminal device A broadcasts the characteristic information and the index information to each node in the block chain network, and at the moment, the terminal device A is also regarded as one node in the block chain network, so that each node in the block chain network can compete for the processing authority of the characteristic information and the index information, if the terminal device A obtains the authority, the terminal device A stores the characteristic information and the index information into a block, and when the data stored in the block reaches a certain data volume, the block is connected to the block chain, so that the storage of the characteristic information and the index information in the block chain is realized.
In another optional embodiment, the process of the terminal device a storing the feature information of the target object in the block chain and acquiring the index information may be further implemented as follows: the terminal device A broadcasts the characteristic information of the target object to nodes in a block chain network so as to enable the nodes to carry out hash operation on the characteristic information to obtain a hash value, and the hash value and the characteristic information are stored in a block chain; the terminal device a further receives the hash value and the chunk identifier sent by the node, where the chunk identifier is an identifier of a chunk storing the hash value and the characteristic information, and at this time, the index information may include the hash value and the chunk identifier.
It can be understood that, after the terminal device a broadcasts the feature information of the target object to each node in the block chain network, each node competes for the authority to process the feature information based on a certain competition mechanism, and assuming that the node B obtains the authority, the node B needs to store the feature information into the block chain. In this process, the node B needs to generate index information corresponding to the feature information and feed the index information back to the terminal device a, and needs to store the index information and the feature information into the block chain, that is, add the feature information and the index information to the current block, and connect the block into the block chain when the data amount of the block reaches a certain threshold.
Optionally, as mentioned above, the index information generated by the node B may include a wallet address of the target object, or may further include a hash value corresponding to the characteristic information, or may further include, in addition to the hash value, a chunk identifier corresponding to the characteristic information, where the chunk identifier may be a number of a chunk storing the characteristic information, or may be a chunk hash value of the chunk. Based on the composition structure of the block chain, a block is composed of a block header and a block body, and the block header contains the hash value corresponding to the block body of the block.
The index information contains the block identifier, and the purpose of the index information is that when the characteristic information needs to be inquired, the block identifier can be directly positioned to the block needing to be inquired based on the block identifier, and then the characteristic information corresponding to the hash value can be inquired from a plurality of information stored in the block based on the hash value corresponding to the characteristic information, so that the inquiry efficiency of the characteristic information is improved.
In summary, regardless of whether the terminal device a generates the index information corresponding to the feature information by itself or receives the index information corresponding to the feature information from another node in the blockchain network, after the terminal device a obtains the index information, an identification code corresponding to the index information may be generated, where the identification code may be a barcode, a two-dimensional code, a QR code, or the like. Furthermore, the terminal device a may associate the identification code with the target object, so that when the inquirer wants to inquire the feature information of the target object, the index information for inquiring the feature information may be automatically obtained only by scanning and identifying the identification code through the inquiring device, so as to further invoke the block chain inquiring interface, and automatically input the index information to the inquiring interface to complete the inquiry of the feature information.
The identification code is associated with the target object, and when the target object is an entity product, the association can be embodied as, for example, attaching a sticker bearing the identification code to the product; when the target object is an electronic product propagated on a network, the association may be embodied, for example, by loading the identification code into a suitable location of the electronic product so that the inquirer finds the identification code.
In the embodiment of the invention, on the premise that the characteristic information of the target object is stored in the block chain, the index information corresponding to the characteristic information of the target object is acquired, the identification code corresponding to the index information is generated, and the identification code is associated with the target object, so that when a user wants to query the characteristic information, the index information serving as a query keyword can be automatically acquired by identifying the identification code associated with the target object, the characteristic information stored in the block chain is automatically queried by the index information, the query keyword does not need to be manually input by the user, and the query efficiency is improved.

201. and identifying the identification code associated with the target object to obtain index information corresponding to the identification code, wherein the index information corresponds to the characteristic information of the target object.
202. And querying the characteristic information stored in the block chain according to the index information.
Optionally, the index information may include a hash value corresponding to the characteristic information, or the index information includes a wallet address corresponding to the target object, or the index information includes a hash value corresponding to the characteristic information and an identifier of a block in which the characteristic information is stored.
In practical application, the query device may be installed with a query application specifically configured to query information stored in the blockchain, and the query application may provide an identification code recognition function, so that a querier may scan and recognize an identification code associated with a target object by starting the identification code recognition function to obtain corresponding index information through analysis, and automatically query the blockchain with the index information to obtain corresponding feature information.
The following describes an example of a storage process of feature information of the target object, an acquisition process of index information, and a query process of feature information in practical application, with reference to the embodiment shown in fig. 3. In the embodiment shown in fig. 3, it is assumed that the terminal device of the owner of the target object is terminal device a, the node B in the blockchain network that obtains the authority to process the feature information of the target object is node B, and the query device of the querier is query device C.
