A fruit and vegetable agricultural product quality safety traceability system based on a block chain

Abstract

The invention provides a fruit and vegetable agricultural product quality safety traceability system based on a block chain, which comprises a fruit and vegetable number generation module, a fruit andvegetable transaction generation recording module, a verification block chain module and a transaction block chain module. The invention utilizes the block chain technology, can ensure that the datain the whole link cannot be tampered with and cannot be replaced, records the whole transaction process through the transaction block chain and verifies the transaction behavior through the verification block chain, thereby solving the integrity and trustworthiness of the quality safety data in the fruit and vegetable agricultural product quality safety traceability system.

Description

technical field [0001] The invention relates to a traceability system, in particular to a block chain-based traceability system for the quality and safety of agricultural products of fruits and vegetables. Background technique [0002] In recent years, food safety incidents have occurred frequently, and a series of quality and safety issues such as bird flu, clenbuterol, melamine, and rice cadmium exceeding the standard have triggered a crisis of consumer trust and are also a major challenge in the country's work in building and developing an honest society. Food quality and safety issues are becoming more and more prominent. Fruits and vegetables, as the basic source of daily nutrition, are getting more and more attention to their safety and quality. Because orchards and farms abuse chemical additives and antibiotics for the rapid growth of fruits and vegetables, it has brought serious threats to the quality and safety of fruits and vegetables, and people are eager to buy r...

AI Technical Summary

Problems solved by technology

[0005] There are still some problems in these existing systems and methods: due to the need to manually collect and enter data, it takes a relatively large amount of time and labor costs for the cultivation process of fruits and vegetables, and is not suitable for traceability in the process of cultivation of fruits and vegetables; in addition, there is no guarantee There is a one-to-one correspondence between data and fruits and vegetables, and the reliability of traceability is difficult to guarantee; (2) Since each agricultural product needs to be equipped with a data acquisition device, the cost of a wireless data acquisition system is too high for the cultivation of fruits and vegetables
