Abstract: The global healthcare sector faces significant difficulties in managing pharmaceutical supply chains, particularly due to issues such as counterfeit medicines, limited transparency, inefficient coordination, and data security vulnerabilities. To address these challenges, this project presents a secure and efficient medicine supply chain management framework based on blockchain technology. The proposed system enhances traceability, transparency, and data security by maintaining an immutable and decentralized record of all supply chain transactions. Smart contracts are employed to automate critical processes including inventory control, order processing, and ownership transfer, thereby reducing manual intervention and operational errors. A decentralized application (DApp) is developed to enable real-time monitoring and verification of medicines throughout their lifecycle using unique digital identifiers. This allows stakeholders to authenticate products and track their movement from manufacturing to end consumption. Additionally, the framework incorporates an optimized Linear Hash Computation (LHC) variant to improve system performance and strengthen data integrity verification. By combining blockchain technology, smart contracts, and efficient hashing mechanisms, the proposed solution provides a reliable and scalable approach for securing modern pharmaceutical supply chains.
