Agricultural supply chain data management system and method based on block chain technology

Abstract

The invention discloses an agricultural supply chain data management system based on a block chain technology. The system comprises an agricultural supply chain data management module, an agricultural supply chain data extraction module, an agricultural supply chain data safety storage module, and an agricultural supply chain data safety access module which are constructed on a block chain network. And information management, storage and access are carried out mutually. According to the agricultural supply chain data management system and method in the technical scheme, based on the block chain and database technology, safe storage and access of large-scale heterogeneous data are guaranteed in combination with an interstellar file system (IPFS) and an intelligent contract technology, and data safety and effective management and optimization are achieved for production nodes, transportation nodes, sales nodes and the like in an agricultural supply chain.

Description

technical field [0001] The application of the present invention belongs to the field of agricultural supply chain data information management, especially the combination of big data technology, block chain, interstellar data system (IPFS), smart contract technology and agricultural supply chain information, through block chain technology to integrate the agricultural supply chain An agricultural supply chain data management system and method based on blockchain technology for comprehensive management of large-scale heterogeneous data in agricultural product production management, transportation records, consumer credit management, and farmer-consumer transactions, thereby ensuring agricultural products from production Data security, transparency, stability, trustworthiness, traceability, information sharing, and high throughput of a series of supply chain activities such as warehousing, transportation, distribution, and sales. Background technique [0002] Agriculture is the...

Problems solved by technology

[0005] In view of the weak data storage and management capabilities in my country's agricultural supply chain, and the inability of all participants to obtain real, accurate, and timely information and updates in the entire process of the agricultural product supply chain, this application proposes an agricultural supply chain based on blockchain technology. The chain data management system and method, its core purpose is to connect agricultural product producers, transportation, consumers and other relevant parties, with the help of blockchain ledger technology, real-time release of information change records in the process of supplying relevant agricultural products on the blockchain network, To ensure the transparency, authenticity and timeliness of information
