Agricultural product quality information system based on block chain

Abstract

The invention discloses an agricultural product quality information system based on a block chain. The agricultural product quality information system comprises a data acquisition module, a block information construction module, a storage sharing module, an evaluation module, and a query module. The data acquisition module is used to acquire soil information and agricultural product type information, and is used to transmit the acquired information in a structured data form to the block information construction module. The block information construction module is used to allocate identity labels for the agricultural products, is used to construct a Merkle tree by using the received structured data, and is used to form block information by carrying out digital signature and time stamp service, and then the p2p transmission of the block information is carried out after work load proof. The storage sharing module is used for the work load verification of the received block information, and after data check, the block information is broadcasted. The evaluation module is used to carrying out the quality evaluation of the agricultural products to acquire quality scores. The query module is used to receive the block information and the quality scores to generate query two-dimensional codes. By introducing the block chain technology, the authoritative and unified agricultural product quality information system is constructed.

Description

technical field [0001] The present invention relates to a technology in the field of information processing, in particular to a blockchain-based agricultural product quality information system. Background technique [0002] With the development of society and economy, people have higher and higher requirements for the quality of agricultural products, but the current situation of the quality and safety of agricultural products is worrying. The "three wastes" in the industry pollute the agricultural production environment. In order to increase production and income, some farmers use a large amount of chemical fertilizers, pesticides, herbicides, etc., resulting in pesticide residues in agricultural products and their processed products in many parts of our country. China is a typical large market and small production model, with low productivity, weak industrialization, and poor standardization. Farmers do not have the awareness and ability to integrate into the product stan...
