Supply chain tracking of drugs using Ethereum

Counterfeiting, increased fake intermediate products, lack of transparency, unauthorized alteration of data, and other related problems throughout the supply chain have made it necessary for the modern pharmaceutical industry to ensure integrity and security. Thus, the above-mentioned problem can be solved by a decentralized blockchain-based system, which ensures security and traceability. In the proposed solution, there are seven stakeholders including manufacturers and consumers. Authorized manufacturers are allowed to store the drugs in the blockchain network, and corresponding QR and bar codes are generated. This generates a reliable record of drug movements by constructing an architecture that is decentralized to avoid alteration of the data by anyone. Consumers have the opportunity to scan QR codes to ensure that their products are genuine and trace their origin. By addressing the challenges of the conventional pharmaceutical supply chain that provides high transparency, minimal counterfeits, and assured data security, this system addresses the aforementioned disadvantages.
