The system is developed by using node.js based on a HyperLegendFabric open source platform. HyperledgerFabric is an open source alliance chain platform developed by IBM, which provides pluggable options and an admission qualification authorization mechanism, and is convenient for technical personnel to develop and manage; the platform uses a plurality of passageways, can keep apart information each other between the different account books, and information mutual noninterference. In order to reduce development difficulty and improve reusability and expandability of a software platform, the system uses a component development technology to make elements in design and development independent and modularized and build the elements by using node.js, wherein a government supervision department comprises a main body ID private key library, an internet server, a distributed database, a file server, a cipher machine and a user qualification server, and the government supervision department respectively carries out data interaction with an logistics end and a sales end.

The terminal equipment comprises an RFID electronic tag, a sensor and a scanner.
The invention explains the following technologies:
1. non-destructive detection technology: an on-line inspection method is used for obtaining physical and chemical information such as contents, properties and components related to the quality of an object to be tested without destroying the original state, chemical properties and the like of the object to be tested.
The existing tracing system solution and application are limited by the current block chain technical conditions, the data before chain linking is encrypted by a production end, and because human factors can not ensure the authenticity and credibility, the data has no credibility and purchase reference value for consumers. In order to solve the problems, the invention mainly utilizes a nondestructive detection technology to carry out online and timely measurement on physical and chemical components of all agricultural product finished products according to a uniform detection method; and according to the national standard or the standard requirement, the AI technology is utilized to intelligently screen out qualified products, the nondestructive detection end is used as an initial node for quality monitoring of the finished products of agricultural products, and real and credible source information is provided for the finished products of agricultural products. The principle of nondestructive testing is shown in fig. 4, and the steps of establishing a nondestructive testing prediction model are shown in fig. 5.
2. Radio Frequency Identification (RFID) technology: the radio frequency identification tag is a communication technology, can identify a specific target and read and write related data through a radio signal without establishing mechanical or optical contact between an identification system and the specific target, and has the advantages of high safety, dynamic change of tag data, high identification speed, batch identification, large data volume, long service life, wide application range, convenience in reading and the like. In order to avoid the phenomena of counterfeit goods and goods fleeing and ensure the uniqueness of the tracing code, the RFID electronic tag design is adopted.
3. Data verification among nodes in a block chain agricultural product quality credible traceability system based on a nondestructive detection technology: hash value and asymmetric encryption
(1) And how the logging information data node and the verification information data node cooperate.
For example, when an agricultural product a occurs at the nondestructive testing end node 001, the node 001 is responsible for recording specific information data of the product a, where the validity of the transaction product a (for example, whether the purchaser has a sufficient balance to pay) needs to be verified, and it is assumed that the product a is legal.
After the nondestructive detection end node 001 receives the product a, the nondestructive detection end node 001 performs hash operation on the product information data to generate a product hash value 001. Then, the hash value 001 is signed (encrypted) by using a private key of the user to generate signature information, wherein the signature information comprises the product hash value 001.
After the node 001 completes the above-mentioned operation, it broadcasts to the outside, and the broadcast content is the original product information a + signature information. The process flow is shown in FIG. 6.
(2) What did the node verifying the data?
Assume that node 002 of the blockchain system receives the broadcast content transmitted from node 001. The node 002 obtains "original product information a" and signature information. Two problems are encountered at this time:
① is the signature information generated by node 001 with its own private key?
② is node 002 unable to determine if original transaction product information a has changed during transmission?
How to solve these problems?
The node 002 can prove that the signature information belongs to the node 001 if the signature information can be decrypted (inverse operation) by the public key of the node 001, and the hash value 001 is obtained after decryption.
The node 002 performs a hash operation on the received "original product information a" to obtain a hash value 002. Whether the transaction information is changed or not is judged only by comparing whether the hash value 001 and the hash value 002 are consistent or not.
If the data are consistent, the data transmission is proved to be correct, and the verification is passed. If the product information is inconsistent with the product information, the product information is proved to be changed, and the verification cannot pass.
Therefore, the problem that two nodes verify the consistency of products is perfectly solved. The process flow is shown in fig. 7 and 8.
4. The commodity blockchain source tracing application scenario is shown in fig. 9.
5. The commodity tracing implementation business logic is as shown in figure 10.
Agricultural product quality traceability relates to a plurality of links such as agricultural product production, storage and transportation, purchase, sale, processing and the like, and efficient cooperation among all modules of the system is an important guarantee for realizing effective traceability of agricultural products. The block chain agricultural product quality credible traceability system constructed by applying the nondestructive detection technology comprises 4 core nodes which are respectively a production end node, a logistics end node, a consumption end node and a supervision department node (figure 11). The tracing process comprises the following steps:
step 1: acquiring information of a production end node, and carrying out online and timely measurement on physical and chemical components of a finished product of an agricultural product according to a uniform detection method by using a nondestructive detection technology after the production end node obtains corresponding authority; according to national standard or international requirements, AI technology is utilized to intelligently screen out qualified products, a non-damage detection end is used as an initial node, physical and chemical component data of the intelligently screened qualified agricultural products are acquired according to the national standard or international requirements, a unique RFID traceability code is identified, and chaining is carried out together with enterprise main body record, transaction information record and agricultural product traceability code information;
step 2: information collection of the logistics end nodes, namely recording logistics enterprise main bodies, transporting information, collecting management and collecting information by collecting management and information collection after the logistics end nodes obtain corresponding authorities;
and step 3: the method comprises the steps that information of a point-of-sale terminal is collected, and after the point-of-sale terminal obtains corresponding authority, the point-of-sale terminal carries out information management and collection, and links the enterprise main body record, the collected management and collected information, the transaction information and commodity information in the circulation process, such as storage state, product quality and other data;
and 4, step 4: supervision and supervision processes, and agricultural product quality tracing has the characteristics of public welfare, complexity, chain property, systematicness and coverage. The construction of an agricultural product quality tracing system cannot be separated from the supervision and management of the government, related organizations such as quality inspection departments and the like play a leading role in ensuring food safety and other problems, the government supervision and management functions run through the whole process of agricultural product tracing, and the government supervision departments perform qualification certification on a production end and a logistics end, add terminals of the production end and the logistics end into a alliance chain as nodes, and simultaneously link supervision information; according to the production, transportation, storage and sale link information of agricultural products and the feedback information of consumers, the production end, the logistics end and the sale end are correspondingly adjusted or rewarded and punished;
and 5: and after the consumer terminal obtains the corresponding authority, the consumer terminal inquires the whole transaction process on specific equipment by scanning the RFID electronic tag, and links the feedback information (such as complaint information, commodity evaluation information and the like) through the equipment.
In the process, the information generates blocks after each node is linked, the distributed databases of all nodes in the alliance chain are updated synchronously, and all nodes in the system have the functions of inquiring and tracking goods.
Aiming at the ubiquitous quality problems of agricultural products, the invention applies a key point control and fault mode, influence and hazard analysis method, inspects and analyzes the front and back quality conditions of each node, and performs false removal and true preservation on the production source of the agricultural product with quality problems by using technologies such as nondestructive detection, Internet of things and AI, so as to ensure that the source information is real and credible, and can trace the source quickly at a consumer terminal, thereby realizing the credible agricultural product quality tracing system with the function of ensuring the quality in advance and the function of tracing the quality afterwards. The agricultural product traceability system data flow using the blockchain technique is shown in fig. 12.
1. At the agricultural product production end: the invention utilizes a nondestructive detection technology, takes a nondestructive detection end as an initial node, carries out modeling according to national standard or row standard requirements, carries out online real-time detection on all produced agricultural product finished products according to a unified detection method, combines the Internet of things and AI technology, removes counterfeit and truthfulness, intelligently screens out qualified products, carries out information acquisition on physical and chemical component data of the qualified products, automatically uploads the information to a node database in real time, generates agricultural product single item information, box code information and code chopping information, and scans and stores the information in a warehouse after identifying a unique RFID traceability code.
When the agricultural products are delivered, manufacturers link manufacturer information, agricultural product single item information, box code information, code chopping information and the like, and provide credible source information with a 'quality guarantee function in advance and a function of tracing back afterwards' for final agricultural product transaction. When a manufacturer transacts with the next node, the commodity is scanned by being cut out of the warehouse, and transaction information is linked up at the moment.
2. Logistics end: and after the logistics end is connected to the commodity, carrying out chopping scanning, chaining the information of the logistics merchants and the commodity state information in the logistics process, and finishing and carrying out chopping scanning.
3. A selling end: and the selling end receives the agricultural products and then carries out warehousing scanning, and carries out chain linking on the node qualification information, the unpacking or unpacking information and the information during the storage period of the commodities.
4. A consumer side: and finally, the agricultural product flows to the hands of the consumers, and the consumers trace the source by scanning the single RFID electronic tags.
In summary, due to the 'timestamp' characteristic of the block chain, information of the commodities in the circulation process is recorded in sequence, when each node receives the commodities, the RFID electronic tags are scanned by the terminal scanner to upload the qualification information and the information of the commodity storage and circulation states to the block chain database, and a consumer or a supervision department obtains the commodity production and circulation information by scanning the RFID electronic tags to perform accurate tracing.
The traditional traceability platform, the blockchain traceability platform and the commodity quality credible blockchain platform are as follows:
based on this, the advantages of the invention are:
firstly, the technical problem of the internet of things is solved. Because the number of nodes is too large, the interaction between the central platform for centrally managing data nodes and data and the agricultural internet of things and the central platform data is difficult to realize in the traditional traceability system, while the agricultural product traceability based on Fabric can pass through a Certificate Authority (CA) authentication mechanism, and the data of the internet of things can be directly written into a data block and recorded into a block chain without being approved by a central role after being acquired, so that the data of the internet of things enters the whole traceability system.
Secondly, the uniformity and the effectiveness of product data are promoted. All data of the blockchain is updated immediately and stored in the database of each node. The data of any node in the whole chain can be extracted to verify the correctness of the data of other nodes, in the whole system, only most nodes (even all nodes) approve the transaction, the feedback result passes through all the nodes, the transaction can be uploaded to the order node, the block is generated, and the block is broadcasted to all the accounting nodes. Under the framework, the transaction information of the quality tracing system is commonly maintained by all nodes, so that the big data analysis of all parties is facilitated, and the risk that the tracing management system is attacked by a hacker or the central database is tampered is reduced.
Third, a new business trust mechanism is established. Based on the characteristics of information uploading of a single node and common maintenance of multiple nodes in the blockchain, a new business trust mechanism can be created in the blockchain. The management concept of ' having a function of ensuring quality in advance and having a function of tracing back afterwards ' that agricultural products have responsibility main bodies for recording, the quality of products at a production end is guaranteed, the responsibility of the main bodies can be traced back, the flow direction of the products can be traced, potential risks can be identified, the degree of harm can be evaluated, and supervision information can be shared ' is really realized.
Fourthly, the responsibility subject is clear, and the tracing cost is low. The distributed ledger enables the part of the node database to be destroyed without any influence on the whole data safety of the system, and the data recording process is open and transparent. Based on the reliable database characteristics, the block chain data cannot be counterfeited, and after the quality problem of the agricultural product is found, the node generating the problem is directly and definitely determined through tracing, the authenticity of the data does not need to be considered, so that the responsibility cost is greatly reduced, and the tracing efficiency is improved.
Fifth, the source contains counterfeit goods. On one hand, the invention uses the nondestructive detection technology to detect all the finished products of agricultural products on line in real time; and the AI technology is utilized to intelligently screen out qualified products, remove the counterfeit and save the truth, and take the data of the nondestructive testing end as an initial node uplink for quality monitoring of the finished products of agricultural products, thereby providing real and credible source information for the finished products of agricultural products. The problem of data counterfeiting caused by human factors at a production end is solved. On the other hand, the system adopts the RFID electronic tag technology, so that illegal vendors cannot copy tag contents. In the third aspect, the block chain passes through a CA access mechanism, has the characteristic that one transaction is recorded by all nodes, and the database of the whole chain cannot be tampered, so that the situation that fake goods enter circulation from the source is guaranteed.
Sixth, efficient big data analysis. The nondestructive detection technology enables block chain agricultural product quality traceability and the RFID technology to ensure the authenticity of data of the whole chain, and the authenticity and the reliability of the analysis of the current industrial situation are improved according to the big data of the chain. The effective big data generated by the method enables the industry added value to be displayed, and further causes the attention and the support of financial institutions and off-site funds.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
