Optimization of Agricultural Product Quality and Safety Traceability Systems in a Multi-Chain Collaborative Framework

The quality and safety of agricultural products are crucial to the development of modern society and constitute a vital factor affecting the interests and development of the entire supply chain. The traditional single agricultural product quality supervision system is gradually unable to meet the increasingly growing market demand. This study addresses the performance bottlenecks and trust barriers of traditional traceability technologies in high concurrency, heterogeneous data, and cross-domain circulation by constructing a blockchain-based full-chain traceability system for agricultural products. It proposes a three-dimensional architecture model that integrates the collaborative functions of the logical layer, physical layer, and data layer, and innovatively designs an intelligent sharding strategy and a chain-network collaborative architecture. These measures effectively improve the utilization rate of distributed storage resources and the speed of traceability response, while significantly reducing the operating costs of the blockchain. Through the collaborative optimization of the heterogeneous multi-chain architecture and chain-network integration technology, the efficiency and security of the agricultural product traceability system are realized. The feasibility of the system is verified through model performance analysis and the design of a traceability system for pilot enterprises, providing references for the application of blockchain technology in the field of agricultural product traceability.
