A patient receiving an authentic drug in India has become a major challenge now. According to the World Health Organization, the counterfeit drug market in India is over Rs. 4000 crore and nearly 20% of the drugs sold in India are counterfeit. Thus, a secure pharmaceutical supply chain requires an end-to-end solution that provides integrity, traceability, and transparency which can be achieved in a data sharing framework, which includes raw material suppliers, manufacturers, third-party logistics, wholesalers, and pharmacies.

The blockchain will have the following participants

A hash (Unique ID) will be assigned to the medicine and it would be registered on the blockchain. Every ID is treated as an asset on the blockchain. At each juncture where the medicine changes ownership, the activity would be time-stamped and recorded on the blockchain. Everyone along the chain can verify the source of origin but at the same time cannot alter it. Moreover, in the case of a defective drug recall, the manufacturer can view the pharmacies that received the affected drug and the pharmacies in turn can directly contact patients who had received those drugs from them.

The participants in the blockchain can record and view transactions. Using smart contracts an immutable ePOD (electronic proof of delivery) of the freight's history will be created.
