A traceability system based on a block chain

Abstract

The invention discloses a traceability system based on a block chain, and relates to the technical field of blockchain and information traceability. The system comprises an alliance chain management module, a block chain browser module, a traceability code generation module, an information storage module, an information reading module, a caching module, a commodity information reading module and an SDK module, and the alliance chain management module can manage and maintain block chain nodes and newly add consensus nodes for key link manufacturers on a supply chain in the block chain. According to the traceability system based on a block chain, the information security Tamper-resistant properties of the block chain are utilized;, the information can be protected from being stolen and tampered; the product information can be kept transparent and public in front of consumers; the credibility of the traditional traceability system is improved, the anti-counterfeiting traceability system can adapt to the existing external traceability means on the market, the anti-counterfeiting traceability work of the original product is supplemented and updated, and multiple anti-counterfeiting processes adopted by manufacturers are simplified, so that the labor and financial cost of the work is reduced.

Description

technical field [0001] The invention relates to the technical field of block chain and information traceability, in particular to a block chain-based traceability system. Background technique [0002] With the exposure of counterfeit and shoddy food safety issues this year, similar issues have received unprecedented attention from the whole society. Food safety issues have not only become the primary factor for people to eat in fear, but also restrict the healthy development of my country's food industry. The current situation of food safety has the following problems: 1. Illegal production by enterprises, and the phenomenon of processed food cannot be ignored; 2. The operation order of the food circulation link is not standardized; 3. The food safety standard system lags behind; 4. The level of inspection and supervision is low and cannot meet the current needs; 5. The quality of the food safety guarantee team needs to be improved. [0003] There are still a series of proble...
