Abstract

The invention provides a method and a system for verifying agricultural product information traceability based on a block chain. The method comprises a traceability step and a verification step. The traceability step comprises: creating an initial block of agricultural products in the block chain, creating a new trading block after the trading role of each link is traded, and linking the trading block to the initial block to form a block chain; according to the mapping relationship between the block chain length and the node performance, the block chain being stored in the node with the corresponding performance. The verification step comprises the following steps: obtaining label information of agricultural products and determining a chain length of a corresponding block chain according to the label information; according to the mapping relationship between block chain length and node performance, the node being traversed from the corresponding performance node to query the block chain of the agricultural product information. According to the queried block chain, the transaction information of each link of agricultural products is verified.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and system for traceability and verification of agricultural product information based on block chains. Background technique [0002] Blockchain technology, also known as distributed ledger technology, is a distributed Internet database technology. With the development of computer technology, blockchain technology (also known as distributed ledger technology) is favored for its advantages of decentralization, openness, transparency, immutability, and trustworthiness. It is widely used in smart contracts, securities transactions, e-commerce, The Internet of Things, social communication, file storage, proof of existence, identity verification, equity crowdfunding and many other fields have been widely used. [0003] At present, agricultural product information can be traced and verified through the Internet and labels on agricultural products. Agricultural product in...
