Agricultural product tracing method based on block chain

Abstract

The invention discloses an agricultural product tracing method based on a block chain, and relates to the technical field of block chains. The method comprises the following steps: a user accesses a traceability system and submits a product anti-counterfeiting code; a web server in the traceability system positions a user node corresponding to the anti-counterfeiting code according to the anti-counterfeiting code; the user node positions a block storage node of the corresponding data chain according to the related hash value; a step of positioning to a database address according to the data block information; a step of returning the data information, the abstract, the information abstract stored in the data block and the abstract of the related data block; a step of analyzing the data information, and comparing whether the abstract stored in the database is the same as the abstract of the related information on the blockchain or not; a step of querying whether the related data block abstract is the same as the related information abstract on the anchoring chain or not; and a step of returning the final result to the query user. According to the method, the credibility and transparency of the traceability information can be improved, agricultural product traceability data sharing is realized, and the supervision cost is reduced.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method for traceability of agricultural products based on block chains. Background technique [0002] The traceability system of agricultural products protects consumers' right to life safety and right to know by providing reliable supervision and credible traceability information. At the same time, the traceability system is also an important link to promote the healthy and stable development of agriculture, and an important guarantee and means to improve product quality and safety. The quality and safety of agricultural products has been widely concerned by people. Initially, the European Union conducted traceability research to ensure the safety of beef in the region, and issued relevant laws and regulations in 2002 to extend product traceability to all foods sold in the EU region. In order to ensure the quality and safety of agricultural products, the United States, Ja...

AI Technical Summary

Problems solved by technology

There may be situations where companies tamper with data for their own benefit, resulting in failure to achieve the goal of credible traceability; damage to the storage medium of data may lead to permanent damage or even disappearance of traceability data

Ultimately, consumers are unable to query relevant traceability information, causing a serious blow to the credibility of the traceability system
