Petri Net Modeling and Analysis of the Drug Traceability System Based on Blockchain

In recent years, blockchain technology has been rapidly developed and widely applied, among which traceability is one of the most important application areas. In this paper, research is carried out around drug traceability (drug traceability refers to achieving the traceability of data from drugs' production to sales). Moreover, a drug traceability model based on blockchain technology is designed and validated. Specifically, the drug traceability system is designed at first, and then the Petri net model of drug traceability system is modeled. Finally, the incidence matrix and PIPE tool are applied to verify the system.
