Illustratively, an application program for inquiring circulation information of an article is installed on a terminal, a user registers a user account through the application program running on the terminal, after the user finishes registration, the terminal sends a registration request to an authorization node in a blockchain platform, the registration request is used for requesting the authorization node to register the user account on the blockchain platform, and the registration request carries the user account.

Step 602, after receiving the registration request, the authorization node determines that the user account is approved, and after registering the user account on the block chain platform, sends registration confirmation information to the terminal.

And after receiving the registration request, the authorization node verifies the user account, and after the user account passes the verification, the authorization node registers the user account on the block chain platform. And after the user account registration is finished, sending registration confirmation information to the terminal.

Step 603, the terminal obtains the item identifier of the item.

The terminal obtains the article identification of the article by scanning the bar code or the two-dimensional code on the package of the article.

Step 604, the terminal sends a query permission request to the authorization node, where the query permission request carries the item identifier.

The terminal sends an inquiry authority request to the authorization node, wherein the inquiry authority request is used for requesting the authorization node to authorize the terminal to inquire circulation information of the article, and the inquiry authority request carries an article identifier.

Step 605, after receiving the query permission request, the authorization node sends permission confirmation information to the terminal after confirming that the item identifier carried in the query permission request is the same as the item identifier stored locally.

After receiving the query permission request, the authorization node detects whether an article identifier carried in the query permission request is stored locally, and if the article identifier is stored locally, the article corresponding to the article identifier is determined to be an article produced by a manufacturer corresponding to the authorization node, so that the terminal is determined to have the query permission, and permission confirmation information is sent to the terminal and used for informing the terminal that the terminal has the query permission.

Because the article identification is the unique code distributed to the article by the manufacturer producing the article, the obtained article identification is sent to the authorization node through the terminal, and the authorization node detects whether the article identification exists in the local verification process, so that whether the obtained article is a forged or fake article can be verified.

Step 606, after receiving the second determination information, the terminal sends a query request to the authorization node, where the query request carries the item identifier.

And after receiving the authority confirmation information sent by the authorization node, the terminal sends a query request to the authorization node, wherein the query request is used for requesting the authorization node to send circulation information corresponding to the article.

Step 607, after receiving the query request, the authorization node traces the block information corresponding to the article in the block chain platform according to the article identifier, and sends the block information to the terminal.

After receiving the query request, the authorization node locally queries whether the block information including the article identifier is stored, if the block information including the article identifier is locally stored, acquires other information in the block information, queries whether the block information including the other information is locally stored, and if the other block information including the other information is locally stored, acquires the other block information. Meanwhile, the authorization node broadcasts an inquiry request to the block chain platform, a target block chain node in the block chain platform responding to the inquiry request locally inquires whether block information including an article identifier is stored, if the block information including the article identifier is locally stored, other information in the block information is acquired, whether the block information including the other information is locally stored is inquired, if the other block information including the other information is locally stored, the other block information is acquired, the acquired block information is sent to the authorization node, and therefore the block information corresponding to the article is obtained in a tracing mode.

It should be noted that the target blockchain node is a blockchain link node responding to the query request, and therefore the authorized node also belongs to the target blockchain node.

For example, as shown in fig. 3, by using an article identifier a, block information 1 and block information 6 may be queried in at least one target block chain node of a block chain platform, and a corresponding relationship between the article information a and package information B in the block information 1 may obtain package information B corresponding to the article information a, and according to the package information B, block information 2, block information 3, and block information 4 may be queried in at least one target block chain node of the block chain platform, so as to trace back to obtain block information 1-6 corresponding to the article a.

In step 608, after the authorization node obtains the block information, the encryption information in the block information is decrypted by using the private key, so as to obtain decrypted block information.

For example, as described in the implementation of fig. 3, each piece of block information may include a piece of encryption information, which is node information encrypted by the public key of the asymmetric encryption key at each circulation node. Therefore, after the authorized node acquires the block information, the encrypted information in each segment of block information is decrypted by the local private key to obtain the node information in each segment of block information, so that the decrypted block information is obtained.

And step 609, the authorization node obtains the decrypted circulation information according to the decrypted block information.

Illustratively, after obtaining each piece of decrypted block information, the authorization node sorts the decrypted block information according to the time stamps in each piece of decrypted block information and the sequence of the time stamps to obtain decrypted circulation information; or, each segment of decrypted block information comprises a serial number, and the decrypted block information is sequenced according to the sequence of the serial numbers to obtain decrypted circulation information; or, according to the info _ key and belong data included in each piece of decrypted block information, sorting the decrypted block information according to the logical relationship to obtain the decrypted circulation information.

Step 610, the authorization node sends the decrypted circulation information to the terminal.

And after the decrypted circulation information is obtained, the authorization node sends the decrypted circulation information to the terminal.

In summary, in the embodiment of the present application, the article identifier is sent to the authorization node in the block chain platform, the authorization node traces the block information corresponding to the article in the block chain platform according to the article identifier, and the circulation information of the article is obtained according to the block information.

Optionally, in this embodiment of the application, the obtained article identifier is sent to the authorization node in the blockchain platform, and the authorization node detects whether the article identifier exists locally to verify the article identifier, so that whether the obtained article is a counterfeit or counterfeit article can be verified.

Optionally, in the embodiment of the present application, the circulation node encrypts the node information by using the public key to obtain encrypted information in the block information, and the authorization node decrypts the encrypted information by using the private key to obtain the node information, so as to obtain decrypted block information, and obtain decrypted circulation information according to the decrypted block information, thereby improving the security of the block information stored on the block chain platform.
