Product tracing method and system based on block chain and storage medium

Abstract

The invention provides a product tracing method and system based on a block chain, and storage medium. The method comprises the following steps: distributing and deploying traceability application andtraceability data on each node of a block chain, and formulating an uplink standard of the traceability information, wherein the uplink standard comprises a database model established according to atraceability requirement and a traceability information processing rule; Receiving traceability information; Depending on chaining criteria, writing the traceability information into the nodes of thecorresponding block chains; integrating the source tracing data of the source tracing information written into the nodes of the block chain, forming a complete source tracing chain according to the integration of raw material purchasing, product production, product logistics transportation, product sales and product payment, generating a source tracing code of the product, and performing source tracing query on the product by utilizing the source tracing code on the transaction label. A real and credible product traceability chain is established by utilizing the characteristic that the block chain cannot be tampered, so that the authenticity problem of the data is effectively solved, and a user can feel that the data of each link is credible.

Description

technical field [0001] The invention relates to the field of product traceability, in particular to a blockchain-based product traceability method, system and storage medium. Background technique [0002] Product traceability has been proposed many years ago. With the continuous development of informatization and intelligence, the entire industry is constantly exploring how to solve this problem, but so far, this problem has not been completely solved. The reason is that In addition to the fact that each link of the product has its own data and identification system, and it is difficult to connect the data of different links, the more important issues are data tampering and data integrity issues. When people go to the supermarket to buy things, they often see green, organic, anti-counterfeiting and other signs, but the credibility of the signs themselves is basically proved by the data provided by the company itself, but this does not guarantee the security and effectiveness...

AI Technical Summary

Problems solved by technology

[0003] In view of the problems of easy data tampering and data integrity in the traditional traceability process, each link of the product has its own data and identification system, and it is difficult to connect the data of different links. More importantly, the problem of data tampering and Data integrity issues, cannot guarantee the security and validity of the provided data
