A multi-model traceability method based on a coalition chain

Abstract

The invention discloses a multi-model traceability method based on a coalition chain. At first, the method of the invention creates the alliance for the enterprises on the commodity line, then the first enterprise records the commodity-related information to the block chain, and then the next enterprise obtains the relevant information through one of the inquiry model, the message model and the transaction model, and then flows the commodity and repeats the operation until the last retail link is reach for the consumer to inquire. By synthesizing three different information extraction models,the method of the invention provides a selectable traceability mode, realizes the anti-counterfeit traceability control aiming at different products and different costs, and reduces the use thresholdand inconsistency of each enterprise through a unified interface mode. Under the advantage of ensuring the security of the block chain, the coalition chain provides a more independent way to solve themost critical performance problems of the block chain. The method of the invention provides a privacy information protection function that allows specific enterprises to maximize the ease of operation and enhance the influence of enterprises, while ensuring the security of private data and protecting the interests of enterprises.

Description

technical field [0001] The invention relates to the technical field of block chain and traceability, in particular to a multi-model traceability method based on alliance chain. Background technique [0002] For a long time, fake and inferior goods have been constantly on the market, which not only harms the interests of consumers but also the interests of regular enterprises, especially for the fresh food industry, and at the same time concerns the lives of consumers. The establishment of a certain anti-counterfeiting traceability mechanism is not only strongly advocated by countries all over the world, but also conducive to enhancing the corporate image and ensuring the interests of consumers. [0003] The birth of Bitcoin triggered the first generation of encrypted digital currency, and Ethereum provided smart contracts on the basis of Bitcoin. People are also paying more and more attention to the underlying technology of the blockchain, which is considered to be the tech...

Problems solved by technology

[0009] The disadvantage of this method is that although the precise information link is realized through the UTXO model similar to Bitcoin, the information blocks of a certain link can be queried in turn for other link information

For commodities with a large number of circulation links, the query efficiency is low, and some commodities with existing unique codes cannot be used, resulting in insufficient use of merchant product codes and waste of resources. At the same time, each link needs to know the information hash of the previous link , increasing communication costs between enterprises

In addition, this solution is mainly based on the public chain, with insufficient consideration for information protection, and it cannot protect the information that only allows upstream and downstream enterprises to share in the circulation chain
