Data storage system, circulating method and tracing method of distributed commodities based on block chain

Abstract

The invention discloses a data storage system, a circulating method and a tracing method of distributed commodities based on a block chain and relates to the field of data tracing. The system is deployed by adopting a league chain mode and comprises multiple super-nodes and multiple common nodes. The data storage system, the circulating method and the tracing method of the distributed commoditiesbased on the block chain solve the problem of non-transparent transaction data in current commodity production and circulation chains, reduce trust friction between enterprises and trust friction between enterprises and supervision departments by utilizing the characteristic that the block chain cannot be tampered, solves the problem of big storage pressure of a centralized tracing platform as thedetail information of the production and circulation links are stored in databases of each enterprise node dispersedly and guarantees the data to be not tampered arbitrarily by the enterprises through the Hash codes, solves the problem of tracing data incompleteness and responsibility positioning difficulty of a supply chain as all the information in the whole life cycle is recorded by regardingthe tracing codes as core and combining with means such as box code association and mobile payment, the responsible party can be positioned rapidly when a quality problem occurs and a recall notice can be sent to related enterprises and related 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 are continuously extended, and they are characterized by fragmentation, complexity, and geographical decentralization, which brings 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 distribution chain, which has caused distrust and friction among the members of the chain. In addition, the production and circulation chain of products involves a wide range of areas, and the supervision is weak. The public lacks a reliable way to verify the quality and source of goods. In response to this situatio...

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...
