Blockchain-based distributed commodity data storage system, circulation and traceability method

Abstract

The invention discloses a distributed commodity data storage system, circulation and traceability method based on blockchain, and relates to the field of data traceability; the system is deployed in a consortium chain manner, including multiple super nodes and multiple ordinary nodes; the invention solves the problem of It solves the problem of opaque transaction data in the current commodity production and circulation chains, and uses the non-tamperable characteristics of blockchain to reduce trust friction between enterprises and between enterprises and regulatory authorities; it solves the problem of high storage pressure on centralized traceability platforms To solve the problem, the detailed information of the production and circulation links are scattered and stored in the database of each enterprise node, and the hash code is used to ensure that these data will not be tampered with without authorization by the enterprise; it solves the problem of incomplete traceability data in the supply chain and difficulty in locating responsibility. Code as the core, combined with box code association, mobile payment and other means, records all information in the entire life cycle, quickly locates the responsible party when quality problems occur, and sends recall notices to relevant enterprises and consumers.

Description

technical field [0001] The invention relates to the field of data traceability, in particular to a blockchain-based distributed commodity data storage system, circulation and traceability method. Background technique [0002] With the deepening of the global division of labor, the production and circulation chains of modern commodities have been continuously extended, and the characteristics of fragmentation, complexity, and geographical dispersion have emerged, which have brought great challenges to supply chain management, production and circulation supervision and product traceability. . This status quo has led to the opacity and information asymmetry of the production and circulation chain, which has led to distrust and friction among the members of the chain. In addition, the production and circulation chain of products involves an extremely wide range, the supervision is weak, and the public lacks a reliable way to verify the quality and origin of commodities. In res...

AI Technical Summary

Problems solved by technology

[0008] 1. There is no guarantee that the data will not be tampered with, and it is difficult to verify the authenticity of the traceable data;

[0009] 2. When a problem occurs, it is difficult to locate the responsible party, and it is often encountered that the responsible party shirks the blame and cannot provide evidence;

[0010] 3. There is an "information island" problem in the traceability code, and the uniqueness of the traceability code cannot be guaranteed, and the production enterprise can generate a large number of identical traceability codes;

[0011] 4. The construction cost of the centralized traceability platform is high and requires a large amount of data storage space;

[0012] 5. The ability to resist attacks is weak. Once the central server is hacked, the entire system will be paralyzed;

[0013] 6. The product tracking chain has not reached the terminal consumers, and it is difficult to recall when there is a quality problem
