Chain Care: Pharmaceutical Supply Chain Management System using Smart Contracts

Abstract

The pharmaceutical supply chain is complex and often faces challenges such as lack of transparency, counterfeit medicines, and inefficient tracking. This project proposes a blockchain-based pharmaceutical supply chain management system using smart contracts to ensure secure and transparent operations. Each medicine batch is recorded on the blockchain with a unique ID, allowing all transactions from manufacturer to pharmacy to be tracked in a tamper- proof manner. The system also enables patients to verify the authenticity of medicines and detect counterfeit products. Additionally, a drug recall feature allows manufacturers to mark defective batches, preventing further distribution. By using blockchain technology, the proposed system improves traceability, enhances security, and ensures trust among all participants in the supply chain
