Detailed Description

For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the embodiments of the present application will be described in further detail with reference to the accompanying drawings.

Before explaining the embodiment of the present application in detail, an application scenario related to the embodiment of the present application is described.

Goods typically pass through multiple circulation nodes from production to sale. For monitoring the commodity, at some of the circulation nodes, the commodity may be marked with a code. For example, a code corresponding to production information may be generated when the production node corresponding to the production plant is passed, and a code corresponding to distribution information may be marked on the commodity when the management node corresponding to the distribution point is passed.

For example, during a production sales process for cigarettes, a code may be generated at a production node to identify the bin of cigarettes. The resulting code is then marked on the box of cigarettes by the production line. After the cigarettes in the box reach the tobacco administration, the corresponding management node of the tobacco administration allocates a corresponding sales node for each cigarette in the box according to the order information, and generates a corresponding code for each cigarette so as to identify each cigarette, and at this time, the code of each cigarette can be marked on the cigarette through a sorting line. For another example, during the production and marketing of white spirit, a code may be generated at a production node that may be used to identify a box of white spirit, the code being used to characterize production information for the box of white spirit. The code is marked on the box of white spirit by a production line. When the box of white spirit arrives at the distribution place, the corresponding authorized retail point can be allocated to the box of white spirit according to the order information of the authorized retail point, a code is generated for each bottle of white spirit in the box of white spirit, and the corresponding code is marked for each bottle of white spirit on the sorting line. The commodity information storage method based on the blockchain provided by the embodiment of the application can be used in the commodity production and sales process such as the example, and the commodity information for monitoring commodity circulation generated in the process can be stored.

The blockchain system related to the blockchain-based commodity information storage method provided by the embodiment of the application is described next.

FIG. 1 is a schematic diagram of a blockchain system 100 in accordance with an embodiment of the present application. As shown in FIG. 1, the blockchain system 100 includes a plurality of nodes 101. The plurality of nodes 101 may include two types of nodes, one type of node refers to a production node that uploads production information, and the node may be deployed in a production mechanism of a commodity. Another type of node refers to a management node that uploads distribution information, and such nodes may be deployed in a distribution management organization for the commodity.

Each node 101 may receive input information while operating normally and maintain shared data within the blockchain system based on the received input information. In order to ensure the information intercommunication in the blockchain system, information connection can exist between every two nodes in the blockchain system, and the nodes can transmit information through the information connection. For example, when any node in the blockchain system receives input information, other nodes in the blockchain system acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored on all nodes in the blockchain system are consistent.

For each node in the blockchain system, the node identification corresponding to the node identification is provided, and each node in the blockchain system can store the node identifications of other nodes in the blockchain system so as to broadcast the generated blocks to other nodes in the blockchain system according to the node identifications of other nodes. Each node can maintain a node identification list shown in the following table, and the node names and the node identifications are correspondingly stored in the node identification list. The node identifier may be an IP (Internet Protocol, protocol of interconnection between networks) address, and any other information that can be used to identify the node, and the IP address is only illustrated in table 1.

Table 1 node identification list

Node name	Node identification
		Node 1	117.114.151.174
Node 2	117.116.189.145
		…	…
Node N	119.123.789.258

Each node in the blockchain system stores one and the same blockchain. The blockchain is composed of a plurality of blocks, referring to fig. 2, the blockchain is composed of a plurality of blocks, the starting block comprises a block head and a block main body, the block head stores an input information characteristic value, a version number, a time stamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a father block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the father block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain are associated with the block data stored in the father block, and the safety of the input information in the block is ensured.

The method for storing commodity information based on the blockchain is described next.

Fig. 3 is a flowchart of a method for storing article information according to an embodiment of the present application. The method can be applied to the blockchain system shown in fig. 1, wherein the production node is the production node introduced in the blockchain system, and the management node is the management node introduced in the blockchain system. Referring to fig. 3, the method includes:

step 301: the production node generates a code for the self-contained commodity and synchronizes the code generated for the self-contained commodity to the blockchain of other nodes in the blockchain system.

In an embodiment of the present application, a production node is a node deployed in a production facility, and the production node is a node in a blockchain system. The self-contained commodity may include a plurality of bulk commodities and the code generated by the production node for the self-contained commodity may include production information for the self-contained commodity. The production information may include information of a production organization, brand information, production date, type of article, production number, and the like. The production number can be an identification of random production for the self-contained commodity, and can also be used for representing the commodity number in a production cycle of the self-contained commodity. For example, the number of the self-contained items within the production day can be characterized.

It should be noted that when a production facility produces a self-contained commodity, the production node may generate a code for the self-contained commodity according to specified rules. Alternatively, other devices in the production facility may generate a code for the self-contained commodity according to specified rules and send the code to the production node. Accordingly, the production node may receive codes generated for the self-contained commodity sent by other devices. The specified rule is a rule for generating a code in a predetermined format based on production information of the packaged commodity.

The code generated for the self-contained commodity is a code containing production information of the self-contained commodity. The code may include a plurality of characters that may be divided into a plurality of character segments, each of which may be used to indicate a type of information in the production information. In addition, it should be noted that the code may be uniquely used to identify the item of merchandise included therein.

Illustratively, a box of cigarettes may be a single self-contained item, and the box of cigarettes may include a plurality of cigarettes, which may be both a plurality of bulk items included in the self-contained item, and a plurality of cigarettes in each cigarette. The multi-box cigarette may be referred to as a plurality of sub-products comprised by the bulk product. The production node may obtain an identification of a production facility that produced the box of cigarettes, a date of production, a brand identification, a type of cigarette to which the box of cigarettes corresponds, and a number of the box of cigarettes. And then, the production node can generate a corresponding first character segment according to the identification of the production mechanism, generate a corresponding second character segment according to the production date, generate a third character segment according to the brand identification, generate a fourth character segment according to the type of the cigarettes, generate a fifth character segment according to the number of the cigarettes, and combine the five character segments to obtain the code of the cigarettes.

After generating a corresponding code for the self-contained commodity, the production node can store the code generated for the self-contained commodity into a memory pool and update a hash tree used for recording input information; then, updating the update time stamp to the time of receiving the code, and trying different random numbers to calculate the characteristic value for a plurality of times, so that the calculated characteristic value can meet the following formula:

SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET

wherein SHA256 is a eigenvalue algorithm used to calculate eigenvalues; version (version number) is version information of the related block protocol in the block chain; the prev_hash is the block header characteristic value of the parent block of the current block; the merkle_root is a characteristic value of input information; ntime is the update time of the update timestamp; the nbits is the current difficulty, is a fixed value in a period of time, and is determined again after exceeding a fixed period of time; x is a random number; TARGET is a eigenvalue threshold that can be determined from nbits.

Thus, when the random number meeting the formula is calculated, the characteristic value, the version number, the time stamp and the difficulty value which are generated by the codes and the calculation and are generated for the whole commodity are correspondingly stored, and the block head and the block main body are generated, so that the current block is obtained. And then, the production node can respectively send the current block to other nodes in the block chain system where the production node is positioned according to the node identification of other nodes in the stored block chain system, the other nodes verify the current block, and the current block is added into the stored block chain after the verification is completed. To this end, the production node synchronizes the code generated for the self-contained commodity to the blockchain of other nodes in the blockchain system.

After the corresponding code is generated for the self-contained commodity, the generated code may also be transmitted to a control device of a production line in the production facility, so that the control device may control a marking device on the production line to mark the code on the self-contained commodity.

Alternatively, the control device may mark the code at a first location on the package of the self-contained item when the code is marked on the self-contained item. At the same time, the control device may acquire the first location and send the first location to the production node. Thus, the production node, upon receiving the first location, may synchronize the code generated for the self-contained commodity with the correspondence of the first location to the blockchain of other nodes in the blockchain system. The first positions of the codes of the marks on the respective self-contained articles may be the same or different. Where different, it may refer to different first locations of the code marked on each self-contained item within a production cycle, e.g., a plurality of self-contained items produced within a day, where the code marked on the self-contained item is located. And a plurality of self-contained articles produced on different production days, the positions of the codes of the marks on the self-contained articles may be the same. In addition, when the first positions of the codes marked on the individual self-contained commodities are identical, in the embodiment of the present application, after receiving the first positions, the production node may synchronize the first positions to other nodes independently, without synchronizing the correspondence between the first positions and the codes generated for the self-contained commodities.

The first position may be any position on the outer package of the self-contained product, or may be a position on the outer package of the self-contained product located on the package opening, which is not limited by the embodiment of the present application.

Alternatively, in one possible scenario, the encoded information may be transcoded after the corresponding code is generated for the self-contained item, resulting in a graphical code. The production node may then transmit the generated graphic code to a control device of a production line in the production facility so that the control device may control a marking device on the production line to mark the one code on each sub-commodity included in the self-contained commodity. Here, for each sub-commodity, a corresponding code may be marked thereon, and for a plurality of sub-commodities belonging to the same self-contained commodity, the code of the self-contained commodity is unique, and thus the codes marked on the plurality of sub-commodities may be the same. The image code may be a two-dimensional code, a bar code, or the like.

Alternatively, in another possible scenario, after generating the corresponding code for the self-contained commodity, the production node may also generate a code based on the code and the number of each sub-commodity, thereby marking the generated code on each sub-commodity. In this case, the code of the indicia on each sub-commodity will be different. The number of each sub-commodity can be the number of each sub-commodity on the production line, and the number is used for indicating the number of the sub-commodity on the production line.

It should be noted that, in the embodiment of the present application, the packaged goods may be sent out and scanned before leaving the warehouse of the production mechanism corresponding to the production node. That is, when the self-contained product is taken out of the warehouse, the code marked on the self-contained product can be identified. And matching the identified code marked on the self-contained commodity with a plurality of codes stored in the blockchain, obtaining the delivery time of the self-contained commodity after successful matching, and synchronizing the corresponding relation between the code marked on the self-contained commodity and the delivery time into the blockchain. The implementation of matching the identified code marked on the self-contained commodity with the plurality of codes stored in the blockchain may refer to the implementation of searching for a code matching the code marked on the self-contained commodity from the plurality of codes stored in the blockchain as described below.

Step 302: the management node obtains the code marked on the self-contained commodity.

In the embodiment of the application, the management node refers to a node which is deployed in a distribution management mechanism and is used for uploading distribution information of commodities.

After the code has been marked for the self-contained article, the self-contained article is transported to a distribution authority. The scanning equipment in the distribution management mechanism can scan and identify the code marked on the self-contained commodity and send the identified code marked on the self-contained commodity to the management node. Alternatively, in one possible scenario, the code marked on the self-contained item may also be scanned and identified by the management node. Alternatively, the staff may enter the code marked on the self-contained item at the management node.

Step 303: the management node checks the code marked on the self-contained commodity according to a plurality of codes stored in the self-configured blockchain.

After the code marked on the self-contained commodity is obtained, the management node can verify the code information marked on the self-contained commodity according to the codes stored in the self-configured blockchain.

Wherein the management node can search codes matched with the codes marked on the self-contained commodity from a plurality of codes stored in the blockchain; if the code matching the code marked on the self-contained commodity is found, the verification of the code marked on the self-contained commodity is passed.

It should be noted that, from the foregoing description, the production node may synchronize the code generated for the self-contained commodity to the blockchain of other nodes in the blockchain system. Since there are multiple self-contained items and there may be multiple production nodes in a blockchain system, there will be multiple codes stored in the blockchain of each node in the blockchain system. On this basis, the management node can search whether the code which is the same as the code marked on the self-contained commodity exists in the blockchain, and if the code which is the same as the code marked on the self-contained commodity is searched in the blockchain, the verification of the code marked on the self-contained commodity can be determined to pass. Alternatively, if the same code as the code marked on the self-contained item is not found in the blockchain, it is indicated that the code marked on the self-contained item is inconsistent with the code stored in the blockchain that was generated for the self-contained item, at which point it may be determined that the code marked on the self-contained item was not verified. That is, the code marked on the self-contained item has been tampered with or is problematic with the self-contained item.

Alternatively, if the production node uploads the code generated for the self-contained commodity into the blockchain at the first location on the outer package of the self-contained commodity, the management node may first take a photograph of the side of the outer package of the self-contained commodity marked with the code before acquiring the code marked on the self-contained commodity. Then, the management node can identify the position of the code marked on the whole commodity in the outer package from the shot image to obtain a second position; then, acquiring a first position from the blockchain; if the first location is the same as the second location, a code for the indicia on the self-contained item is obtained.

If the first locations corresponding to the self-contained commodities are the same in step 301, the management node may directly obtain the first locations from the blockchain. After acquiring the first location, the management node may compare the first location to the second location. If the two positions are identical, the position of the code marked on the self-contained commodity is identical to the position marked at the production node, then the management node can acquire the code marked on the self-contained commodity, and execute the operation of checking the code marked on the self-contained commodity in the step.

Alternatively, if the first positions corresponding to the self-contained articles are different, in the embodiment of the present application, the management node may further identify the code marked on the self-contained article from the captured image after identifying the second position from the captured image. The management node may then look up the blockchain for a code that matches the code marked on the self-contained item. If the code of the current mark on the self-contained commodity is found, the code generated for the self-contained commodity is consistent with the code stored in the blockchain, at the moment, the management node can acquire a first position corresponding to the found code, compare the first position with a second position, and if the two positions are identical, the position of the code marked on the self-contained commodity is consistent with the position marked at the production node. In this case, since the code and the mark position of the mark on the self-contained product are both verified, the management node can confirm that the code of the mark on the self-contained product is verified.

Step 304: if the verification of the code marked on the self-contained commodity is passed, the management node self-contained commodity marking code and the information of the sales node corresponding to each of the plurality of bulk commodities generate a code for each of the plurality of bulk commodities.

If the management node passes the verification of the code marked on the integral commodity, the management node can acquire order information sent by each sales node and allocate a corresponding sales node for each of a plurality of bulk commodities included in the integral commodity according to the currently received order information. The management node may then generate a code for each bulk commodity based on the information of the sales node corresponding to each bulk commodity and the code marked on the self-contained commodity. Wherein the code of each bulk commodity comprises production information and distribution information of the corresponding bulk commodity. Likewise, the code for each bulk commodity may contain a plurality of characters that may be divided into a plurality of character segments, wherein each character segment may be used to indicate a different message.

For example, the management node may obtain the identifier of the sales node allocated to each bulk commodity, generate a character segment according to the identifier, take the codes marked on the self-contained commodities to which the plurality of bulk commodities belong as a character segment, and combine the two character segments to generate the code on each bulk commodity.

Optionally, in some possible cases, the management node may further obtain an organization identifier of a distribution management organization to which the management node belongs and an identifier of an administrative area in which the distribution management organization is located, generate a character segment according to the identifier of the distribution management organization, generate a character segment according to the identifier of the administrative area, and use the two character segments as character segments in the encoding of each bulk commodity.

Optionally, the management node may further assign a number to each of the plurality of bulk goods, where the number of each bulk good is different, and the number of each bulk good is used to indicate a sorting position of the corresponding bulk good in the associated self-contained good. In this case, the management node may also use the number of each bulk commodity as a character segment in the code of each bulk commodity.

For example, still taking cigarettes as an example, when a box of cigarettes enters a distribution management mechanism, the distribution management mechanism may assign a corresponding sales node to each cigarette in the box of cigarettes according to order information, and then generate a code for each cigarette according to the identification of the sales node corresponding to each cigarette, the code marked on the box of cigarettes, the number of each cigarette, the mechanism identification of the distribution management mechanism, and the identification of the administrative area in which the distribution management mechanism is located.

After generating a code for each bulk commodity, the management node may send the code generated for each bulk commodity to the control device of the sorting line of the distribution management facility so that the control device controls the marking device on the sorting line to mark the code generated for the bulk commodity on the corresponding bulk commodity.

Step 305: the management node synchronizes the code generated for the bulk commodity into the blockchain of other nodes in the blockchain system.

After generating the corresponding code for each bulk commodity, the management node may refer to the foregoing method for the production node to synchronize the code generated for the self-contained commodity to other nodes in the blockchain system, and generate a corresponding block according to the code generated for each bulk commodity and synchronize the block to other nodes in the blockchain system, which is not described herein in detail.

Because each bulk commodity is marked with a code, and the management node uploads the code generated for each bulk commodity to the blockchain system, after the bulk commodity arrives at the sales node, the sales node can acquire the code marked on each bulk commodity, and check whether the bulk commodity has a problem or not by comparing the code marked on each bulk commodity with the code generated for the corresponding bulk commodity stored in the blockchain.

In the embodiment of the present application, before each bulk commodity is distributed to each sales node, that is, when each bulk commodity leaves the management node to be delivered, the management node may identify the code marked on each bulk commodity, find the code matching the identified code marked on each bulk commodity from the plurality of codes stored in the blockchain, and after the code matching the identified code marked on each bulk commodity is found, obtain the delivery time of each bulk commodity, and synchronize the correspondence between the delivery time and the identified code marked on each bulk commodity to the blockchain system. The method for searching the codes matched with the codes marked on each bulk commodity from the plurality of codes stored in the blockchain can refer to the implementation manner for searching the codes matched with the codes marked on the whole commodity from the plurality of codes stored in the blockchain, and the embodiment of the application is not repeated herein.

In addition, in the embodiment of the application, the first position of the mark code on the whole commodity can be uploaded to the blockchain, and the management node can check the position of the code mark while checking the code of the mark on the whole commodity, so that the checking accuracy is improved.

As can be seen from step 301 in the previous embodiment, each sub-item included in the self-contained item may be marked with a code. In this case, after the consumer purchases the sub-commodity from the sales node, the related information of the sub-commodity can also be queried from the blockchain through the code marked on the sub-commodity. Fig. 4 shows a method for querying information of a commodity according to a code marked on a sub-commodity according to an embodiment of the present application, as shown in fig. 4, the method includes the following steps:

step 401: and the target node receives a query request sent by the terminal, wherein the query request carries the code to be queried.

Wherein, because the same blockchain is stored on each of the plurality of nodes included in the blockchain system, the target node may be any of the plurality of nodes included in the blockchain system based on the same.

In the embodiment of the present application, the consumer terminal may scan and identify the code marked on the target sub-commodity, and as known from the foregoing embodiment, the code marked on the sub-commodity may be a graphic code. In this case, the terminal may parse and transcode the scanned code, thereby obtaining the code to be queried. And then, the terminal can carry the code to be queried in the query request and send the query request to the target node. Or if the code marked on the sub commodity is a character code, the terminal can directly identify the code, so that the code to be queried is obtained.

The terminal may scan the code of the mark on the target sub-commodity through a small program, or may scan the code of the mark on the target sub-commodity through other specific applications, which is not limited in the embodiment of the present application.

Accordingly, the target node may receive a query request carrying a code to be queried sent by the terminal.

Step 402: the target node searches for a code matching the code to be queried from a plurality of codes stored in a self-configured blockchain.

After receiving the query request, the target node can search whether the code matching the code to be queried exists in the self-configured blockchain. Since the code of the mark on the sub-commodity is determined according to the code generated for the self-contained commodity stored in the blockchain, if the target sub-commodity has no problem and the code of the mark on the target sub-commodity is not tampered, the code to be queried obtained according to the code of the mark on the target sub-commodity will be the same as the code of the self-contained commodity to which the sub-commodity stored in the blockchain belongs. Based on this, the target node may search the blockchain for the same code as the code to be queried, and if so, it indicates that the sub-commodity has no problem, at this point, the target node may perform step 403.

Alternatively, in one possible implementation manner, since the code generated by the management node for each bulk commodity includes the code of the self-contained commodity to which the corresponding bulk commodity belongs, and the management node uploads the code generated for each bulk commodity to the blockchain, in this step, the target node may also search for the code including the code to be queried from the plurality of codes stored in the blockchain. If so, the target node obtains each code found and block information of the target block where each code found is located, and performs step 403.

Optionally, if the code identical to the code to be queried is not found in the blockchain, the commodity information indicating the sub commodity is not stored in the blockchain, and at this time, the target node may return a query failure notification message to the terminal, so that the terminal displays the query failure notification message, thereby prompting the consumer that the commodity information of the sub commodity is not stored in the blockchain.

Step 403: and if the code matched with the code to be queried is found, the target node sends the block information of the target block to the terminal.

The block information of the target block may include a block number and a generation time of the target block. The target node may determine the generation time of the target block according to the timestamp stored in the block header of the target block. The block number of the target block refers to the number of the target block in the blockchain.

It should be noted that if the code identical to the code to be queried is found, the terminal may store the specified rule for generating a code for each self-assembled commodity and the information represented by different characters in each character segment described in the foregoing embodiment, and the terminal may analyze the code to be queried according to the specified rule and the information represented by different characters in each character segment, so as to obtain the production information of the target sub-commodity. And displaying the production information of the target sub-commodity and the block information of the target block.

If the code containing the code to be queried is found, the terminal can analyze the found code according to a specified rule, so that the production information and the distribution information of the target sub-commodity are obtained, and the production information and the distribution information of the target sub-commodity and the block information of a target block where the found code is located are displayed. It can be seen from the foregoing description that the production node may upload the delivery time of each individual commodity to the blockchain, and the management node may upload the delivery time of each bulk commodity to the blockchain, where in this case, the production information may further include the delivery time of the sub-commodity at the production node, and the distribution information may include the delivery time of the sub-commodity at the management node, the identifier of the distribution management mechanism corresponding to the management node, the identifier of the administrative area to which the management node belongs, and so on.

Fig. 5 is a diagram of a query result page obtained by querying a terminal according to a code marked on a target sub-commodity according to an embodiment of the present application. As shown in fig. 5, the terminal may parse the code obtained by the query to obtain the production organization, brand, date of production, type of product, block number, and block generation time of the target sub-product, and display the same.

In the embodiment of the application, each sub-commodity is marked with a code, so that after a consumer purchases one sub-commodity, the consumer can search the code matched with the code marked on the sub-commodity from the blockchain by scanning the code marked on the sub-commodity, thereby verifying the authenticity of the sub-commodity and acquiring commodity information of the sub-commodity.

The storage and querying of merchandise information during the creation and sale of cigarettes is described next in connection with fig. 6. As shown in fig. 6, for a box of cigarettes, the production node may generate a code for the box of cigarettes, which may be a code containing a plurality of numbers, for indicating the production organization, brand information, date of production, type of cigarettes, production number, etc. of the box of cigarettes. The cigarette type may refer to the shape type of the box of cigarettes, such as a special-shaped cigarette, a conventional-shaped cigarette, and the like. After generating the corresponding code for the box of cigarettes, the production node may synchronize the code to other nodes in the blockchain system. Meanwhile, the production node may generate a graphic code according to the code generated for the box of cigarettes, and send both the generated graphic code and the code generated for the box of cigarettes to the control device of the production line, where the control device controls the marking device to mark the graphic code on the box body of each box of cigarettes in the box of cigarettes, see fig. 7. The cigarettes are packed into a plurality of cigarettes and then packed into boxes, and the control device controls the marking device to mark a code on the box body of each box of cigarettes. When the cigarettes leave the production mechanism, the cigarettes are checked out of the warehouse, and the time of the cigarettes out of the warehouse and the codes on the cigarettes are uploaded to the blockchain. The cigarettes are transported to a management node, the management node can acquire the code information marked on the box body of the cigarettes, find the code matched with the code marked on the box body in a plurality of codes stored in a blockchain, and if the code matched with the code marked on the box body is found, the cigarettes are qualified. The management node may then assign a corresponding sales node to each of the cigarettes in the bin based on the currently received order information, and generate a code for each of the cigarettes based on the sales node assigned to each of the cigarettes, the code marked on the bin, and the number of each of the cigarettes. The codes generated for each cigarette are synchronized to other nodes in the blockchain system and each cigarette is marked with a code. The management node can then scan the code of the code marked on each cigarette for delivery before delivering each cigarette to the warehouse, and upload the code marked on each cigarette and delivery time to the blockchain. Thereafter, each cigarette is transported to a respective sales node.

Subsequently, for the sales node, the sales node may look up the merchandise information for each cigarette from the blockchain based on the code marked on that cigarette. For consumers purchasing individual cigarettes in each cigarette, the blockchain may be queried for production information and/or distribution information for each cigarette by scanning the graphical code on the box.
