Abstract

The embodiment of the invention provides a product traceability method and system based on double block chains, being characterized by processing existing cloud computing data and server resources ofan enterprise, constructing a double-blockchain fusion model based on a private chain and a public chain by combining a high-efficiency private chain mode and a cross-chain technology, effectively fusing the cloud computing data and the block chain, and extracting cloud computing data and recording hash values of the cloud computing data into a private chain, and the private chain traceability necessary data is uploaded to the public chain, so as to ensure data tampering prevention and subsequent verification, thus realizing high-efficiency interaction between cloud computing data and on-chaindata, reducing the difficulty of deploying a blockchain system by an enterprise, finally realizing intelligent generation of product traceability information, and meanwhile, eliminating human factorsof information circulation among main bodies of a supply chain, so that traceability information authentication which is more accurate, and more complete and more reliable than traditional product traceability is generated.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of block chains, in particular to a product traceability method and system based on dual block chains. Background technique [0002] Product traceability is an important means of modern supply chain management. As food safety issues are getting more and more attention, the traceability of products such as food and agricultural products currently needs to solve the balance of data credibility, privacy, and efficiency. Blockchain is an efficient way to keep stored data trusted. [0003] Most of the original product original information data of the production enterprise is efficiently stored and operated through the cloud computing center, and the block chain technology, especially the public chain model, has the problem of low efficiency, and the product traceability is heavily dependent on the original product of the enterprise Original information data, how to combine blockchain te...
