Agricultural product traceability system based on block chain

Abstract

The invention provides an agricultural product traceability system based on a block chain. The system comprises an agricultural product big data platform, an agricultural product traceability query platform, and a 5G network; the agricultural product big data platform comprises an agricultural product growth information module, a storage information module, a processing information module and a sales information module; the agricultural product traceability query platform comprises a data restoration module, an anti-counterfeiting query module and a traceability information query module; and each module carries out data uploading and traceability query through a 5G network. According to the invention, further optimization is carried out on the basis of a traceability system based on a block chain; an agricultural product tracing system combining the advantages of a private chain and a public chain is designed. On the basis of preventing the agricultural product information from being attacked and tampered, the certified product label is further prevented from being stolen and copied, the data storage efficiency is improved, the calculation expenditure is reduced, and consumers or supervision departments can quickly position production links and responsible persons of problematic agricultural products.

Description

Technical field [0001] The present invention relates to the field of agricultural product traceability systems, in particular to an agricultural product traceability system using blockchain technology. Background technique [0002] With the continuous growth of consumers' consumption level of agricultural products, people have higher and higher requirements for the quality and safety of agricultural products. In order to solve the supervision of agricultural product quality and safety, it is particularly necessary to establish a reliable and transparent agricultural product traceability system. For the regulatory authorities, when an agricultural product safety incident occurs, the agricultural product traceability system can quickly query detailed information about the entire process of agricultural products from production, storage, processing to sales, and accurately identify the problematic link and responsible party, so as to improve the quality of agricultural products. And...

Problems solved by technology

Second, due to the use of asymmetric encryption algorithms and hash algorithms, the tampering of the data of a single node will lead to the modification of the data of other nodes on the blockchain, and the workload is too large for the system to bear, so the modification of the database by a single node is invalid, ensuring The recording and transmission of data is reliable and cannot be tampered with

[0006] 1. If the traceability information of each agricultural product is stored in the public chain, the overhead of calling smart contract storage is too high;

[0007] 2. In the public chain, it is difficult to serialize and store the traceability information of different formats and sizes, the storage efficiency is low, and the amount of information storage is small;
