In recent years, blockchain technology has emerged and gained considerable attention due to its reliability and secure data sharing capabilities in various domains such as supply chain management, finance, the internet of things, agriculture, food, healthcare, and pharmaceutical industries. The track of pharmaceutical supply chains has become more critical in the health society in any country or region to ensure the proper trackability and safety of medicines. With time, it has become more complex and costly to track thousands of various medical products. Without a proper supply chain system, there is a possibility of the availability of counterfeit drugs. Building a traceability system over a blockchain platform would provide a trusted and secured method to track and trace the medical supply chain from the manufacturer to the patient. This work proposes a traceability system for pharmaceutical products in Oman using blockchain technology to maintain the integrity of the data of such sensitive valuable products. In addition to this, different pharmaceutical workflows have been designed and implemented using the Ethereum blockchain platform.
