Embodiment Construction

[0030] In order to briefly introduce the operation mechanism of the traceability system, we take the food supply chain of ham sausage as an example, which includes the roles of suppliers, processing companies, distributors and other participants.

[0031] Breeding (production) link - the main role is the farm: the farm first identifies all livestock and poultry and enters them into the blockchain, completes the creation of their own product information documents, and then enters the birth information of livestock and poultry, feed Information, dispensing information, epidemic information, sales status and other specified information, when the livestock and poultry are sold and flow to the next link (slaughtering process), the current responsible party node initiates a transaction request and signs the embedded with the slaughterhouse using the private key In the smart contract in the blockchain, the system records the transaction operation and automatically authorizes the recei...

Abstract

The invention discloses a food safety traceability system based on a block chain technology, which belongs to the technical field of food safety traceability, and comprises a physical layer, an interface layer, a database layer and a communication layer which are applied to the block chain technology, the decentralization degree and the consensus mechanism in a block chain can be reasonably adjusted by utilizing the technical generality of distributed storage characteristics, asymmetric encryption and the like of the block chain and introducing supervision departments and standard organizations, so that the decentralization degree and the consensus mechanism in the block chain are improved under the condition that an existing food safety traceability system is not complicated. The problemsthat a traceability system is non-standard in information collection and unsafe in data storage, a centralized system is easily attacked, and the privacy of the information exchange process between enterprises cannot be guaranteed are solved in a targeted mode, and the invention is suitable for wide application and popularization.

Description

technical field [0001] The invention belongs to the technical field of food safety traceability, and in particular relates to a food safety traceability system based on block chain technology. Background technique [0002] In recent years, food safety incidents have occurred frequently, and a series of quality and safety issues such as bird flu, clenbuterol, melamine, and rice cadmium exceeding the standard have triggered a crisis of consumer trust and are also a major challenge in the country's work in building and developing an honest society. The food traceability system can identify the source of food and provide detailed information on the whole process from production to table. Once a food safety accident occurs, the food traceability system can quickly and accurately locate the problem link, clarify the responsible party, recall the problem food in time, and curb the spread of the problem. This is one of the effective ways to solve the current food safety crisis. The...
