Problems solved by technology

[0005] The current agricultural product traceability system has the following problems: (1) The traditional system based on centralized storage has the possibility of data tampering
(2) Some agricultural product traceability systems using block technology have problems such as slow transaction speed and malicious node attacks
(3) Most of the blockchain-based agricultural product traceability systems do not design a corresponding chain structure for the nature of agricultural product traceability, and there may be waste of storage space and time overhead

Abstract

The invention discloses an agricultural product traceability method based on a block chain technology. The agricultural product traceability method comprises the following steps: a, storing agricultural product data; b, storing an agricultural product tracing chain; C, a consensus mechanism suitable for an agricultural product traceability chain; According to the method, the requirements of largeagricultural product traceability trading volume and rapid trading are effectively met, the influence on the system performance is reduced to a certain extent, and the threat to the system stability is reduced.

Description

technical field [0001] The invention relates to the field of computers, in particular to a method for traceability of agricultural products based on block chain technology. Background technique [0002] The continuous occurrence of agricultural product safety accidents and recalls of agricultural products in the global market has aroused more and more people's attention to the quality of agricultural products. The quality of agricultural products is related to the life and property safety and vital interests of every consumer. Both production enterprises and consumers hope to know the relevant information about the raw materials and sources of their final agricultural products or consumer products, so as to ensure the reliability and safety of agricultural products. properties and understand their level of quality. Although the State Bureau of Agricultural Products and Drug Quality Supervision attaches great importance to the prevention and treatment of related problems, th...
