Description

Block chain-based product information storage method, device and system

Technical Field

The embodiment of the specification relates to the technical field of block chains, in particular to a method, a device and a system for storing product information based on a block chain.

Background

At present, when a product side manufactures a product, each part manufacturer is required to manufacture required parts, and then the parts are assembled to manufacture the product, so that the product is put on the market. For example, when manufacturing automobiles, automobile manufacturers generally entrust various parts manufacturers to produce required parts such as engines, doors, tires, and steering wheels, and then assemble the parts to manufacture automobiles.

After purchasing a product, a customer typically has a need to query information about the product. The product-related information may specifically include information on a production side of the product, an expiration date or warranty date of the product, product logistics information, product usage information, and the like.

The customer can judge the product quality according to the inquired product related information. For example, whether a producer of the product is in compliance or not, whether the validity period of the product is overdue or not, whether the product is used or the length of time for which the product is used, and the like are judged.

Product related information is often stored in a distributed manner in different locations. For example, logistics information is stored in a logistics company, validity period and warranty period information is stored in a product production side, part information of an assembled product is stored in a part production side, and maintenance information of a product is stored in a maintenance side.

When a client or other mechanism with inquiry requirements inquires the relevant information of the product, the information needs to be inquired from each party, the operation is troublesome, and the credibility of the relevant information of the product inquired from each party is low, so that the relevant information can be modified by each party. For example, a product producer may extend the life of a product for reasons such as evading liability.

Detailed Description

In order to make those skilled in the art better understand the technical solutions in the embodiments of the present specification, the technical solutions in the embodiments of the present specification will be described in detail below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only a part of the embodiments of the present specification, and not all the embodiments. All other embodiments derived by one of ordinary skill in the art from the embodiments given herein are intended to fall within the scope of the disclosure.

For example, for automobile products, after purchasing an automobile, a customer wants to be able to inquire whether a manufacturer of the automobile is a regular manufacturer, so as to preliminarily determine the quality of the automobile. If the customer purchases a second-hand automobile, the customer also wants to be able to inquire whether the second-hand automobile is damaged, the used time and other information.

In addition, other mechanisms exist that have the need to query for information about a product.

For example, a regulatory department may also have a need to query product-related information, control the quality of products circulating in the market, and reduce the potential safety hazards of the products. For example, the regulatory authorities often need to spot check cars on an irregular basis, query relevant information about the cars to be checked, and check for compliance. The damage and the service condition of the automobile to be detected can be checked, and the potential safety hazard of the automobile is reduced.

For example, for a product imported and exported, the customs department needs to query product-related information to determine whether the product is prepared in a regular way, for example, a compliant logistics company prepares the product to the customs department. If it is determined that the product is not circulated through a regular route, the product may be temporarily paid.

For example, when an automobile insurance company carries out a business, it is usually necessary to query relevant information of an automobile to determine the specific situation of the automobile. Specifically, when the insurance line is evaluated aiming at the automobile, the related information of the automobile can be inquired, and the past damage condition and the use condition of the automobile are determined, so that a reasonable insurance line is evaluated.

Taking automobiles as an example, the automobile products themselves often have different qualities and production conditions.

For example, there may be refurbished automotive parts that are refurbished using old automotive parts, defective automotive parts produced by a compliant parts producer, triple defective automotive parts produced by a non-compliant parts producer, used automotive parts that are disassembled directly from other automobiles in the market. Automobiles assembled or repaired using these inferior automobile parts often have large quality problems, which may cause serious safety accidents.

For example, in the automobile trading market, a bad merchant often pretends a three-handed and four-handed automobile to be a second-handed automobile, and deceives the consumer to purchase the automobile with the use time greatly exceeding the safety range, so that a great safety hazard exists. Alternatively, a bad merchant considers a smuggling car as a regular imported product to raise the price, which disturbs the car market order.

At present, no specific scheme is available for automobile supervision and quality control, and automobile owners often have difficulty in acquiring credible automobile related information after purchasing or maintaining automobiles, so that great economic loss and potential safety hazards are borne.

In order to solve the technical problem, an embodiment of the present specification provides a block chain-based product information storage method.

In the method, a block chain can be newly added, and the related information of the product is uploaded to the block chain by each party for storage. Specifically, the corresponding relationship between the product identifier and the product information set may be deployed in the blockchain, and each party may store the product-related information stored in the party itself into the product information set corresponding to the product identifier in the blockchain according to the product identifier.

By means of the characteristics that the blockchain is difficult to tamper and is traceable in the whole process, all parties can store the product related information into a credible environment comprehensively, and when inquiring the product related information, a client or other organizations with inquiry requirements can trust that the product related information is not tampered after being stored into the blockchain, so that the credibility of the information is improved.

In addition, the client or other mechanisms with query requirements only need to query information in the block chain, and do not need to query from all parties, so that query operation is simplified.

It should be noted that when each party stores the product-related information in the blockchain, because the blockchain has a multi-party signature mechanism, each party needs to attach its own digital signature when sending a transaction, so that the product-related information uploaded by each party cannot be repudiated, and can be used as an evidence in post-audit, thereby warning each party not to do malicious work and improving the credibility of the product-related information.

In an optional embodiment, a corresponding blockchain account may be created for a product, so that product-related information is stored in fields such as a balance of the blockchain account corresponding to the product in the world state of the blockchain.

Specifically, after the product producer assembles the new product, a corresponding blockchain account is created in the blockchain for the new product (which may be a transaction initiated by the product producer to create a blockchain account and associate the created blockchain account with the new product). And other parties may store the information about the new product in the record of the blockchain account corresponding to the new product.

Because the records of the blockchain accounts in the world state need to be anchored in the blockchain, the product-related information stored in the blockchain account corresponding to the product is difficult to be tampered. And any operations performed on the blockchain account corresponding to the product are recorded into the blockchain.

Optionally, the blockchain account corresponding to the product may include a product identifier as a basis for storing or querying the related information.

In this embodiment, a product may uniquely correspond to a blockchain account, thereby facilitating storage or querying.

In another alternative embodiment, the product and corresponding product-related information may be stored directly in the transaction, and the transaction itself may be stored in the blockchain, thereby enabling storage of the part-related information.

Specifically, each party directly packs the product identification and the corresponding product related information into a transaction to be stored on the blockchain. When the product related information is specifically inquired, the transaction in the block chain can be traversed, and the product identification to be inquired and the corresponding product related information are determined. Of course, the blockchain may also construct an index according to the product identifier, which facilitates determining the transaction location containing the corresponding product-related information.

In the embodiment, the specific operation is simple to realize, and the product related information in the transaction is more difficult to tamper.

In another alternative embodiment, the product-related information may be stored using smart contracts.

Alternatively, the product-related information may be stored in the contract account by the smart contract itself. Specifically, each party may send a transaction to the intelligent contract account, where the transaction includes product-related information, so that the intelligent contract may store the product-related information in a field of the contract account or in another storage area. The smart contracts may anchor the stored product-related information to the blockchain to prevent tampering.

The intelligent contract may create a table or a set when storing the product-related information, where one or more sets of product identifiers and product-related information may be stored.

Further, optionally, the storage method in the above 2 embodiments may also be executed by the smart contract.

For example, corresponding blockchain accounts may be created for a product by a smart contract, or product-related information may be stored in a transaction by a smart contract.

Specifically, a transaction to create a blockchain account may be initiated by the smart contract and the created blockchain account may be associated with a product. Or the intelligent contract sends the transaction to itself, and the product identification and the corresponding product related information are stored in the transaction.

Because the execution process and the execution result of the intelligent contract are both recorded in the blockchain and are difficult to be tampered, the storage process and the storage result can be reserved and anchored to the blockchain to prevent tampering.

The following explains a block chain-based product information storage method provided by an embodiment of the present specification with reference to a specific embodiment.

The basic concepts involved in the process flow of the method are explained first.

Block chain network: for convenience of description, the device related to the blockchain is determined as a blockchain network as a whole, wherein each node device of the blockchain may be included.

Product identification: the product may be uniquely associated with an identifier at the time of manufacture. The identifier may be a unique field string, and may include a product manufacturer identifier, a production date, a production lot, a specific serial number, and the like.

Optionally, to facilitate determining the identity of the product, the product may be caused to carry the identity in some manner. For example, the product identification is carved on the product by a special process, so that the carved product identification is difficult to modify or is easy to find after modification. For example, for an assembled car, it may uniquely correspond to a vehicle identification number or frame number. The vehicle identification number is a group of seventeen letters or numbers, is used for a group of unique numbers on the automobile, and can identify the manufacturer, the engine, the chassis serial number, other performance and other data of the automobile.

As a specific example, in the conventional automobile industry, a vehicle identification number (i.e. a frame number or VIN code) is a set of seventeen letters or numbers as an international common standard, and is used for a unique set of numbers on an automobile to identify the manufacturer, engine, chassis serial number and other performance data of the automobile. The vehicle identification code is arranged and combined, so that the phenomenon of repeated identification can not occur within 30 years of vehicle type production, and the vehicle identification code has unique identification on the vehicle. Automobile manufacturers need to report and apply for vehicle VIN codes to the jurisdictional countries for national unified management before developed vehicles are ready to leave factories and sell. The VIN code of an automobile is globally unique.

The production method of the product comprises the following steps: a mechanism for producing a product. For example, an automobile manufacturer.

Product information uploading party: and the mechanism is used for developing related businesses of the products and generating related information aiming at the products. For example, a logistics company for transporting products may generate logistics information for the transported products; an insurance company for providing an automobile insurance business, which can generate insurance information for automobiles, etc.; a repair company, which repairs product replacement parts, may generate part replacement information or assembly information for an automobile.

It should be noted that the product producer may also act as a product information uploader to generate the relevant information.

For example, the product producer may generate production-related information for the product, such as production date, production place, and the like, and may perform quality inspection to generate quality inspection result information to be stored in the blockchain network.

Specifying an intelligent contract: and the intelligent contract is used for maintaining the corresponding relation set of the product identification and the product information set.

The corresponding relation between the product identification and the product information set can be stored in the block chain, so that the credibility of the product information is improved, and the product information is prevented from being tampered. The designated intelligent contract may maintain the corresponding relationship set, specifically, create a new corresponding relationship, add new product information to the product information set, and the like.

It should be noted that the designated intelligent contract may include one or more intelligent contracts, and optionally, the operation of the entire maintenance set may be performed by a single intelligent contract, or the operation of the maintenance set may be shared by a plurality of intelligent contracts.

For convenience of understanding, in the following method flow, one intelligent contract may be selected to perform all maintenance operations, and the embodiment in which multiple intelligent contracts share the execution operations may also be obtained by simple reasoning based on the method flow, and therefore, the embodiment in which multiple intelligent contracts share the execution operations is also within the disclosure of the present specification.

Fig. 1 is a schematic flowchart of a block chain-based product information storage method provided in an embodiment of the present disclosure.

The block chain network can store a designated intelligent contract, and the designated intelligent contract is used for maintaining a corresponding relation set of the product identification and the product information set; the block chain network is connected with at least one product producer and at least one product information uploading party in an opposite mode; the product assembling party is used for assembling a product by utilizing at least one part; the product information uploader is configured to generate the relevant information for the product.

The method may include the following steps.

S101: after any product producer assembles any new product, calling a specified intelligent contract to execute: creating a group of corresponding relations between new product identifications and product information sets for the new products, and adding the created corresponding relations into the corresponding relation sets; for any part used to assemble the new product, the identification of that part is added to the set of product information corresponding to the identification of the new product, if specified.

S102: after any product information uploading party generates target information aiming at a target product, a specified intelligent contract is called to execute: and adding the target information into a product information set corresponding to the identification of the target product.

It should be noted that the above steps S101-S102 are not limited to a definite time sequence relationship, and may be executed in parallel or sequentially.

For the product producer and the product information uploader interfaced with the blockchain network, in an optional embodiment, for any product producer, the blockchain network may check in advance whether the product producer is compliant, and if so, the blockchain network may interface with the product producer. In particular, compliance may be determined by the blockchain network on a business basis.

Optionally, the specifically checking whether the product producing party is compliant may include checking whether a qualification rate of the product produced by the product producing party is greater than a preset qualification rate, and the like.

For example, the blockchain network may be managed by a government agency that may monitor the production of the product producer to verify compliance.

Of course, the non-compliant product producer cannot pass the check of the blockchain network, and the produced product identifier cannot be queried in the blockchain. The user can trust that products corresponding to the product identifiers existing in the blockchain network are all produced by a compliant product producer, so that the quality of the products is conveniently controlled.

In addition to the above-described verification for the product producer, in an alternative embodiment, compliance verification may also be performed for any product information uploader. If compliance is determined, the blockchain network may interface with the product information uploader.

Optionally, the specific checking of the product information uploader may include checking whether the product information uploader qualifies to generate the related information for the product.

For example, for an automobile, the product information uploader includes at least a regular 4S store, and cannot include an unqualified automobile assembly plant or other non-certified vendor.

In this embodiment, the non-compliant product information uploader cannot upload product related information through the inspection of the block chain network, so that the quality of the product can be controlled conveniently.

In an optional embodiment, the correspondence set may be stored in a contract account corresponding to the specified intelligent contract, and specifically may be stored in a field of the contract account.

In another alternative embodiment, the corresponding relation set may be stored elsewhere in the blockchain, but the corresponding relation set needs to be anchored on the blockchain to prevent tampering. Specifically, the hash value of the entire correspondence set may be stored in a contract account corresponding to the specified intelligent contract.

In another optional embodiment, the correspondence set may be stored in a transaction in the blockchain, and specifically, each set of correspondences in the correspondence set may be stored in the transaction. For example, the product information uploader may package the correspondence between the product identification and the product-related information in a transaction and upload to the blockchain. The operation of storing information in the embodiment is simple, and the stored information is difficult to tamper.

In another alternative embodiment, the set of correspondences may be stored in a world state. Specifically, one blockchain account may correspond to one product identifier, and a product information set corresponding to the product identifier is stored in the blockchain account.

With respect to S101, in an alternative embodiment, after any new product is produced by any product producer, a product identifier may be uniquely associated with the new product.

Optionally, the new product may be made to carry a product identification. The unique product identifier can be directly fired or imprinted on the new product, so that a product information uploading party or other users or mechanisms needing to inquire product related information according to the product identifier can directly execute the service according to the identifier carried on the product.

In one particular embodiment, the new product may include: an automobile. Correspondingly, the identification of the new product may include: a unique identification code for the car. The product identification can be used to distinguish products, facilitating determination of uniquely corresponding products.

Therefore, the product identification can facilitate uploading and querying of relevant information of the product. The product information uploading party can conveniently determine the corresponding product information set according to the product identification, so that the product information is stored in the corresponding product information set. And a user or an organization with query requirements can query the corresponding product information set according to the product identification.

In addition, the product producer can also be used as a product information uploading party to store part of product related information in the product information set in advance.

For example, the product producer may generate information such as production date, expiration date, warranty period, etc. for a new product, and store the information in the product information set corresponding to the new product identifier.

Specifically, when creating a corresponding relationship between a set of new product identifiers and a set of product information, in an optional embodiment, any product identifier uniquely corresponds to a set of product information.

Alternatively, where the designated intelligent contract stores a set of correspondences in its own contract account, the designated intelligent contract may create a set of correspondences and store the created correspondences in the set of correspondences of its own contract account.

Alternatively, in the case where the blockchain account corresponds to the product identifier, the designated intelligent contract may create a blockchain account, correspond the new product identifier to the created blockchain account, and create a product information set in the created blockchain account, specifically, create a product information set in a field of the created blockchain account.

Optionally, in the case that the correspondence is stored in a transaction, the designated intelligent contract may package the new product identification into a transaction that is uploaded into the blockchain as a create transaction for creating the correspondence. And then if any party needs to store the product related information in the product information set, directly packaging the product identification and the product related information into a transaction and sending the transaction to a block chain, wherein the specified intelligent contract can check whether a created transaction corresponding to the product identification exists, and if so, the received transaction can be stored.

Specifically, during verification, the designated intelligent contract can traverse the transaction in the block chain to search for a creating transaction containing the product identifier, and the product identifier of the creating transaction can be stored in the contract account in advance, so that the product identifier can be directly searched in the contract account of the designated intelligent contract, and the verification is convenient.

After creating the correspondence between the product identifier and the product information set, the identifier of the part used to assemble the product may be added to the corresponding product information set as product-related information.

Wherein each part may also have a unique identification. Since the product itself is assembled from parts, the identification of each part constituting the product can be used as product-related information to characterize the parts included in the product. Of course, if parts in subsequent products are replaced, part identifications in corresponding product information sets may be further replaced.

In an alternative embodiment, the blockchain network may also interface with at least one part producer, which may be used to produce parts, and create a unique corresponding identification for each produced part.

To make the part identification authentic, the part identification may also be added to the blockchain. Specifically, after any part producer produces any new part, the identity of the new part is stored in the blockchain network.

Alternatively, the blockchain network may interface any part producer after determining that the part producer is compliant. Specifically, the method may be to determine the compliance of the part production side from the business, or to determine the qualification rate of the parts produced by the part production side.

Based on the credible part identifier, in an optional embodiment, before the part identifier is added to the corresponding product information set, only the part identifier already stored in the blockchain network may be limited to be stored in the product information set, so that the credibility of the product related information is improved, and the forged or non-compliant part identifier is prevented from being stored in the product information set.

Therefore, the specific specified cases in S101 may include: the identifier of the part is stored in the blockchain network.

For S102, in an optional embodiment, the product information uploading party may be a product seller, and after the product is sold, the information related to the sales situation may be stored in a product information set corresponding to the sold product in the block chain network, so as to characterize the use situation of the product.

In an alternative embodiment, the product information uploading party may also be a consumer, and after purchasing a product, the user information may be stored in the blockchain network to represent that the product has been purchased by the user, which is used as a basis for determining new products and second-hand products.

It should be noted that, because the block chain network has the characteristic of leaving traces in the whole process, any product information uploading party needs to sign the stored product-related information to prevent repudiation. Therefore, the risk of storing error information or modifying information by the product information uploading party can be reduced, and the record stored according to the block chain can be rolled back at any time, so that the accuracy of the related information of the product is ensured.

For the target product in S102, optionally, any product may be used, and for convenience of description, the product is described as the target product; after any product information uploading party carries out business aiming at the target product, the generated related information is called target information.

Through the above steps S101-S102, the related information of the product may be stored in the blockchain by using the specified intelligent contract, specifically, the related information of the product may be stored in the product information set corresponding to the product identifier.

Wherein the related information may include one or more of the following information: the system comprises logistics information of the product, information of a producer of the product, information of parts contained in the product, content for representing whether the product is damaged or not, content for representing whether the product is in compliance or not, content for representing whether the product is qualified or unqualified by the producer of the product, and content for representing that the product is produced by the producer of the product which is in compliance or not.

After the product related information is stored in the block chain, the query of a user or an organization with the query requirement can be facilitated. Specifically, the query can be performed in the blockchain according to the product identifier.

In an alternative embodiment, any user or authority may invoke a specific smart contract to perform: and inquiring and returning a product information set corresponding to the product identifier from the corresponding relation set based on the product identifier to be inquired.

In this embodiment, a user or an organization can conveniently query according to a product identifier, and on one hand, the credibility of the queried product information can be determined to be higher based on the trust of the block chain, so that the quality of the product or the source of the traced product can be determined, and the risk of potential safety hazard or economic loss is reduced.

In a specific embodiment, information related to the automobile, such as automobile production data, whole automobile and part data, logistics circulation data, part replacement data and the like, can be uploaded to a block chain for storage, so that the whole-process datamation and transparentization of the automobile information can be realized, the information fragmentation of the automobile market is broken, and the whole-process traceability is realized. The user or the mechanism can conveniently inquire the full flow of the automobile according to the unique identification of the automobile.

Meanwhile, the information of maintenance, repair and part replacement of the automobile is uploaded to the block chain, so that the situations that the abandoned parts are not sold again and the like in good order can be prevented, and the potential safety hazard or the economic loss of a user is reduced.

In an alternative embodiment, any product producer, any part producer, or any product information uploader may query product information or other information in the blockchain based on the requirements.

For example, an insurance company needs to query historical damage conditions of automobiles, and in the case that a traffic department or other departments store the damage conditions of automobiles in a blockchain network, the insurance company can conveniently query corresponding historical damage conditions in the blockchain network through automobile identifiers, and the credibility of the queried information is high.

For example, a customs company needs to label a reported import/export automobile product, and specifically, the import/export permission may be stored in an automobile information set corresponding to an automobile identifier in a block chain network. The logistics company or other organizations can conveniently inquire the corresponding automobile information set in the block chain network according to the automobile identification, and determine whether the automobile is in compliance by judging whether the set contains import and export permission.

For example, in order to monitor the sales situation of the produced product, the product producer may query the blockchain network for the corresponding sales situation according to the product identifier, in case the sales store stores the sales situation in the blockchain network.

For example, since the part identifier included in the product is already stored in the blockchain network in S101, the part producing side can determine the product assembled by the corresponding part according to the part identifier, and further track the use condition of the part.

Based on the analysis, each party related to the product can use the blockchain network as a shared trusted database, and each party can store the product-related information generated by the party to the shared trusted database and read the information stored by other parties for carrying out the business.

Because the data in the trusted database is difficult to be tampered and is traceable in the whole process, the credibility is greatly improved, and all parties can better utilize the credible related information of products to develop business; and because the product related information of other parties can be obtained only by interacting with the trusted database, the interaction cost is greatly reduced.

In addition, the product-related information stored in the blockchain may also have other roles, for example, facilitating the supervision of the product by a regulatory body.

In an alternative embodiment, the blockchain network may also be interfaced to at least one supervisor; a supervisor may be used to check whether a product is in compliance.

The embodiment does not limit how to judge whether the product is in compliance.

Optionally, determining whether the product stores the product identification in the blockchain at the time of production may be included. Specifically, any supervisor may invoke a specific intelligent contract to execute: and based on the identifier of the product to be checked, if the product information set corresponding to the identifier cannot be inquired from the corresponding relation set, determining that the product to be checked is not in compliance.

Obviously, if the product information set corresponding to the identifier cannot be queried from the corresponding relationship set, the product producer does not create a corresponding relationship for the product identifier, and the block chain does not have product related information and does not meet the specification. In the case where only a compliant producer can interface to the blockchain network, it is apparent that the product may be produced by a non-compliant producer.

Optionally, the method may further include determining whether a product information set corresponding to the product in the blockchain meets a specified check condition. Specifically, any supervisor may invoke a specific intelligent contract to execute: based on the identifier of the product to be checked, if the product information set corresponding to the identifier inquired from the corresponding relation set meets the specified checking condition, determining that the product to be checked is not in compliance, and adding the content for representing that the product to be checked is not in compliance into the product information set corresponding to the identifier.

The specified checking condition may be used to judge the condition of the product according to the product information set corresponding to the product. In particular, quality situations, damage situations, etc. may be mentioned.

Optionally, the specified checking condition may include one or more of the following conditions: the product information set comprises damaged contents for representing the product to be checked; the product information set comprises content for representing non-compliance of the product to be checked; the product information set comprises the identification of the parts which are not assembled in the product to be checked; the product information set does not include the identification of the parts assembled in the product to be checked; the product information set comprises content for representing that the product to be checked is determined to be unqualified by a product producer; the product information set contains contents for characterizing that the product to be checked is produced by a non-compliant product producer.

When the product information set comprises the damaged content for representing the damaged product to be checked, the product to be checked is damaged, and then the supervisor can determine that the product to be checked is not compliant. The content characterizing the damage of the product to be checked can be uploaded by the traffic accident management department according to the products involved in the traffic accident.

When the product information set comprises content for representing the non-compliance of the product to be checked, the supervisor can directly determine that the product to be checked is not compliant. The content for characterizing the non-compliance of the product to be checked may specifically include: and the product producer or the logistics party determines the quality inspection result that the quality of the product to be inspected is unqualified during the quality inspection.

When the product information set comprises the identification of the parts which are not assembled in the product to be checked, it is indicated that part of the parts may be disassembled in the product to be checked, so that the product to be checked cannot be normally used or potential safety hazards exist. For example, the corresponding automobile information set of the automobile includes an identifier of a safety valve part, but the safety valve part does not exist on the automobile, and obviously, the automobile has a quality problem, so that a supervisor can determine that the product to be checked is not qualified.

When the product information set does not include the identification of the parts assembled in the product to be checked, the fact that the parts which are not normally installed exist in the product to be checked is indicated. It may be particularly the case that the repair party replaces the non-compliant part while repairing the product. For example, if the identifier corresponding to the engine part in the automobile is not included in the product information set, the engine part may be an out-of-compliance part, the automobile has a quality problem, obviously does not conform to the specification, and the supervisor may determine that the product to be checked is out of compliance.

When the product information set contains the content for representing that the product to be checked is not qualified by the product producer, it is obvious that the product to be checked is not qualified by the producer, but is circulated in the market in violation of the regulations, so that the supervisor can determine that the product to be checked is not qualified.

When the product information set contains content for characterizing the product to be checked, which is produced by a non-compliant product producer, the producer itself is not compliant, and the produced product is obviously not compliant. For example, the product manufacturer produces a product with a low pass rate and a product with a high pass rate that fails. Thus, the regulatory party may identify that the product to be checked is not compliant.

After determining that the product to be checked is not in compliance, the supervisor can put the product to be checked off shelf, specifically, recycle or destroy the product, and add the content for representing that the product to be checked is not in compliance to the product information set corresponding to the identifier, which indicates that the product to be checked is not suitable for market circulation, so as to facilitate subsequent user or mechanism query.

According to the method, by means of the characteristics that the blockchain is difficult to tamper and the whole course of the blockchain is marked, all parties can store the product related information into a credible environment comprehensively, when inquiring the product related information, a client or other organizations can trust that the product related information is not tampered after being stored into the blockchain, and as the uploading parties of the product related information are recorded by the blockchain, the malicious uploading parties can be determined through post audit, so that the risk that the uploading parties forge the product related information is reduced, and the credibility of the information is improved.

In addition, under the condition that a client or an organization inquires credible product related information, the product quality can be effectively judged, product traceability and the like are carried out, the true and false and traceability operations of the product can be conveniently verified by the client, so that the risk and potential safety hazard of economic loss are reduced, and the product with poor replaced quality is avoided.
