Blue crab quality traceability system based on a block chain

Abstract

The invention discloses a blue crab quality traceability system based on a block chain, which comprises a plurality of data acquisition modules and an application program module, and is characterized in that the number of the data acquisition modules is determined by the number of supply chain enterprises participating in blue crab traceability, and each supply chain enterprise is configured with one data acquisition module; the application program module comprises a client module and a block chain network module; the block chain network module is composed of a Channel module, a Consensus module and a Chaincode module; and the client module is provided with an enterprise client, a consumer client, a supervision department client and an administrator client; four roles of a related enterprise, a supervision department, a system administrator and a consumer can access a client of a corresponding role through a browser or an app, and interact with the block chain network module to realize functions of each role. The method has the advantages of high reliability and capability of ensuring the authenticity of traceability data.

Description

technical field [0001] The invention relates to a mud crab quality traceability system, in particular to a blockchain-based mud crab quality traceability system. Background technique [0002] Most of the existing traceability systems for blue crabs involve the four roles of relevant enterprises, regulatory authorities, system administrators and consumers, and are constructed based on the four stages of breeding, processing, storage, transportation and sales. In these four stages, it is necessary to collect and input the data information of blue crabs, and finally realize that consumers can enter the traceability code to query the traceability information of blue crabs from breeding to sales. [0003] The existing blue crab traceability system is mainly composed of multiple data collection modules and application modules. The number of data collection modules is determined by the number of supply chain companies participating in the blue crab traceability. Each supply chain c...

Problems solved by technology

[0004] However, the existing blue crab quality traceability system has the following problems: the database module is based on the traditional centralized data storage method, and the central node is vulnerable to centralized attacks, resulting in the failure of the entire system to operate normally and causing huge losses; the centralized system In the administrator mode, the data is easily tampered with. The participation of the supervisory department cannot protect the system data itself, but only has a control over the overall supply chain process, but the traceability data information will still be tampered with.

In summary, the existing blue crab quality traceability system has problems in the reliability of the system and the authenticity of the data
