Medsupplychain: A Blockchain-Based Drug Tracking and Verification System

Abstract

The pharmaceutical industry faces critical challenges related to counterfeit drugs, poor traceability, and lack of transparency in supply chain management. To address these issues, this project proposes MedSupplyChain, a blockchain-based drug tracking and verification system that ensures secure, transparent, and tamper-proof management of pharmaceutical supply chains. The system leverages Ethereum smart contracts to automate key operations such as drug batch registration, transfer of ownership, and recall management with role-based access control for manufacturers, distributors, and regulators. Decentralized storage using IPFS is integrated to securely store certificates, testing reports, and product images, while only their hash values are recorded on the blockchain to maintain efficiency and scalability. The frontend DApp, built with React.js and connected via Web3.js/Ethers.js, provides user specific dashboards for stakeholders and enables real-time verification of drug authenticity. Patients, pharmacists, and regulators can easily track and verify drug batches using batch IDs, ensuring accountability and trust across the supply chain. This approach not only reduces the risks of counterfeit drugs but also improves regulatory compliance, operational transparency, and stakeholder collaboration. By combining blockchain's immutability with decentralized storage, MedSupplyChain establishes a secure, efficient, and trustworthy foundation for modernizing pharmaceutical logistics.
