Description

Technical Field

[0001] The present invention relates to the field of intersection of electrical engineering and information technology, and in particular to a blockchain-based quality traceability system and method for the entire forest and grass seedling industry chain, integrating technologies such as mobile client device data collection, distributed storage, and smart contracts. Background Art

[0002] In recent years, the number of applications for new plant variety rights in my country has continued to grow, but cases of variety infringement have become frequent. This is due to an incomplete seedling intellectual property protection mechanism and siloed information records within the industry chain, making it difficult to trace infringements. Furthermore, regulatory authorities lack effective oversight tools, and the high cost of rights protection is particularly prominent. There is an urgent need to establish a comprehensive, industry-wide traceability system for forest and grass seedling quality. This system can quickly identify the source of quality issues, clarify responsibilities, and effectively reduce losses for growers, which is crucial for promoting the healthy development of the seed industry. Existing technical pain points include the vulnerability of traditional traceability systems to data tampering (a security risk associated with centralized databases), information silos across the industry chain (data from nurseries, logistics, and planting processes are not interoperable), and inefficient paper-based file management.

[0003] However, my country has yet to establish a mature forest and grassland seedling traceability system covering the entire industry chain. Existing traditional forest and grassland traceability systems all use centralized databases for information management, and are often deployed within enterprises. Limited by their enterprise-specific application scope, these traceability systems lack unified standards for information collection, and inter-system information exchange channels are limited. This situation results in inefficiencies for regulatory authorities in areas such as seedling transaction supervision and infringement evidence collection. This independence and hindered information flow are known as information silos. Blockchain, as a unique data storage and management architecture, enables data sharing and verification between nodes through a decentralized system. Blockchain technology offers advantages such as distributed storage, immutable data, and high security. These advantages are highly compatible with seedling traceability requirements. Not only can it accurately record information on the entire seedling circulation process, facilitating the construction of a comprehensive variety rights database, but it can also effectively address technical shortcomings within regulatory authorities, providing reliable support for addressing the challenges of seedling traceability supervision. It demonstrates high feasibility and practical value in this field. Summary of the Invention

[0004] The purpose of the present invention is to solve the problem of quality information tracking of the entire industry chain of forest and grass seedlings in the existing technology, and a blockchain-based forest and grass seedling quality traceability system and method is proposed.

Traceability coding is performed based on the industry chain data and monitoring data, and a quality traceability network for the entire industry chain of forest and grass seedling circulation is constructed. The industry chain data corresponding to the data to be traced is determined through a unique traceability QR code; it can improve the efficiency and accuracy of quality traceability of the entire industry chain of forest and grass seedlings, and at the same time has good anti-tampering properties, and can be directly applied to the quality traceability system of the entire industry chain of forest and grass seedlings.

DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] Please see the attached Figure 1 , a blockchain-based quality traceability system for the entire forest and grass seedling industry chain, adopts a layered architecture design, including user layer, application layer, data layer, smart contract layer, blockchain layer and traceability information database; User layer: covers the user entities that use the forest and grass seedling traceability system, including variety rights holders, nursery companies, seed production and processing companies, consumers, and regulators; Application layer: provides users with a human-computer interaction platform, based on mobile apps, WeChat mini-programs, web-based backend management systems, and blockchain API interfaces, connecting the complex underlying blockchain technologies with actual business needs; Data layer: Deploy mobile APP devices to collect data information on the entire forest and grass seedling industry chain (variety identity information, growth and breeding information, circulation information, and transaction information). The data layer is the data foundation of the entire system and requires its participation in all data addition, modification, deletion, and query. Only when the data storage is authentic and reliable can the traceability results and feedback be meaningful. Smart contract layer: Smart contracts verify whether conditions are met in real time, complete corresponding operations, and record operations on the chain, ensuring the traceability of the transaction process; Blockchain layer: This layer uses an improved Fabric consortium chain architecture (with a timestamp service module) to automatically store data on the blockchain through an automatic triggering mechanism for transaction chain data smart contracts. This layer is the core technology layer of the system, ensuring data security through encryption algorithms, distributed storage, consensus mechanisms, and other technologies. This ensures that data cannot be tampered with, is decentralized, and is fully traceable, thus achieving the purpose of tracing the origin of forest and grass seedlings. Traceability information database: stores information on four links of the seedling industry chain, including seedling identity information, seedling production information, seedling transaction information, and user information, with a total of 127 fields.

[0022] The essence of traceability is to transform the physical flow in the supply chain into information flow, so that subsequent queries based on the information flow can obtain key production information and its production process of specific products; therefore, the specific information content required for the construction of the traceability information database directly determines whether the forest and grass seedling traceability system can operate effectively.

[0023] Please see the attached Figure 2 A blockchain-based quality traceability method for the entire forest and grass seedling industry chain includes the following steps: S1: The business process starts with the variety right holder or improved variety certificate holder uploading the certificate information into the system, completing the title confirmation and authentication, and then entering the seedling identity information into the system and publishing it to the platform; S2: Consumers select seedlings based on their needs on the seedling information interface and then wait for delivery after submitting a purchase request and receiving approval. S3: The consumer confirms receipt of the goods and the transaction is completed. The system will automatically integrate the entire transaction process information and upload the data to the chain through unified system operations to ensure data security. S4: If the consumer has the qualifications for seedling production and operation, he or she can switch the role from consumer to seedling dealer by entering seedling information.

[0024] In a preferred embodiment, the source of the supply chain is the starting point of the entire traceability information chain record; the seedling transaction information contains the source and destination information of the batch of seedlings, and a traceability information chain is formed by connecting the source and destination information of the seedlings.

[0025] System implementation process 1. System Development Environment: The system utilizes a client / server (C / S) architecture to implement core system functions, such as seedling information entry, editing, and review. JDK 8 was used as the Java Development Kit (JDK), and MySQL 8.0 was used as the relational database management system (RDBMS) for data storage and management. Maven 3.8.x was selected as the build tool to facilitate project dependency management and build. Redis 6.x was used as the caching technology to improve the system's data access performance.

[0026] 2. Blockchain deployment: The system uses the consortium chain Hyperledger Fabric and channel technology to establish a forest and grass seedling traceability system to ensure the isolated storage of traceability data. The on-chain certificate management agency audits node identity and node transaction authorization, and achieves data consensus backup through the Randomized Agreement for Fault-Tolerant (RAFT) consensus mechanism. The off-chain state database Couch Database (CouchDB) is used to store on-chain traceability records.

[0027] 3. Smart Contract Implementation: Based on the business logic of the forest and grassland seedling traceability system, design smart contract functionality, including functions for recording seedling production information, updating transaction status, and querying detailed information about seedlings at each stage. Define the format of the smart contract's input and output parameters to ensure that different parties can easily call the contract and obtain the required information. The Java language, with its robust ecosystem and rich class library, is particularly well-suited for teams with a large pool of Java developers. Writing smart contracts in Java facilitates data interaction and sharing with existing systems, reducing system integration costs and improving development efficiency.

[0028] System application function display 1. Seedling information input function: such as Figure 3 As shown, after the seedlings are produced, the seedlings can be put on sale by clicking to enter the seedling information. After entering the seedling entry interface, the company needs to first select the source of the seedlings, which are mainly divided into three types: self-research, online purchase, and offline purchase. When choosing self-research or online purchase, the system will automatically jump to the interface, retrieve the corresponding self-research variety information or online purchase order information, and complete the rapid filling of seedling information. This can improve the efficiency and accuracy of seedling entry, and at the same time, the seedling flow path can be fully recorded, which is conducive to improving the accuracy and depth of traceability work.

[0029] 2. Seedling order query function: such as Figure 4 As shown, users can view their own and currently selling seedlings and their detailed information through the [My Seedlings] and [My Orders] interfaces in the [My] interface. The [My Orders] interface contains all the user's orders, including purchases and sales, as well as order classifications at different stages. Users can view the corresponding seedling information to obtain the required information. 3. Traceability QR code download and query function: Figure 5As shown, users can download seedling traceability codes from the [My Traceability Code] interface. The system supports filtering and downloading traceability codes for owned seedlings, sold seedlings, and purchased seedlings. The generated QR code will be saved as a file package and can be directly called and printed in a local folder. All users can query the corresponding seedling information by scanning the QR code.

[0030] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: it can greatly improve the security of seedling data in the entire industry chain, provide technical support for variety rights protection, effectively solve the data island problem of ordinary traceability systems, and realize the full traceability of seedlings from the source of the industry.
