Blockchain based solution for Pharma Supply Chain Industry

Modern pharma supply chain systems are complicated, involving manufacturers, suppliers, and consumers that span across continents. To date, there is a considerable lack of transparency in the movement and sale of pharmaceutical products sold online. Lack of transparency, mistrust in collaboration, and unwillingness to share data can be huge challenges for this global industry. In this paper, we propose a blockchain-based framework for the online sale of pharma products, in a decentralized manner with no intermeies such as hospitals or pharmacies. The proposed solution is based on utilizing Ethereum smart contracts, to monitor the interaction between participants, trigger events that are logged to help the participants to keep track and be informed about sale transactions, and ensure payment dispersal securely. In addition, smart contracts regulate the interaction between sellers and consumers by monitoring the status of IoT containers, including pharmaceuticals, and fully notifying consumers. Our smart contracts handle special cases related to consumer refunds in case of breach of contract terms to ensure the safe delivery of medicines.
