The Design and Implementation of Catering Safety Tracing System Based on Block Chain

In recent years, catering safety problems have occurred frequently, and people increasingly hope that catering safety can be guaranteed. A catering safety tracing system is designed and developed to solve catering safety traceability problems. Block chain is a de-centralized database which uses distributed book database to store data. By block chain technology, this system can ensure the reliability of traceability information. By a web application and a hybrid APP, users can manage and query trace information. The SSM (Spring + Spring MVC+ Mybatis) framework which are used in the web application development simplifies the development and reduces the deployment difficulty.
