Agricultural product traceability system based on block chain

Abstract

The invention discloses an agricultural product traceability system based on a block chain, relates to an agricultural product traceability technology, and is used for solving the problem that a traditional agricultural product traceability method depends on the Internet, so that information data can be randomly tampered, and the traceability credibility is low. The agricultural product growth information, the agricultural product transportation information, the agricultural product sales information and the agricultural product purchase information are all stored in the block tree; the block tree comprises a block trunk, a plurality of block branches and a plurality of block leaves, the plurality of block branches are distributed on the block trunk, and the plurality of block leaves are distributed on the block branches; the block trunk is used for storing transportation information of agricultural products, the block branches are used for storing sales information of the agricultural products, the block leaves are used for storing purchase information of the agricultural products, and the block leaves can only obtain storage information of the block branches; and the block branches can only obtain the storage information of the block trunk.

Description

technical field [0001] The invention belongs to the field of block chain, relates to agricultural product traceability technology, specifically a block chain-based agricultural product traceability system. Background technique [0002] In order to improve the safety experience of consumers of agricultural products, agricultural product manufacturers attach a QR code containing the manufacturer's information and the information of the source of agricultural products to the packaging of agricultural products produced. After purchasing agricultural products, consumers can scan the code to obtain the production Manufacturer information of agricultural products and information on origins of agricultural products. [0003] However, in this method of traceability of agricultural products, the content that consumers can trace is limited to the information of the manufacturer of agricultural products and the information of the source of agricultural products. In the link of agricultu...
