Experimental Evaluation of Blockchain Based Drug Supply Chain Management System to Ensure Transparency and Traceability

The pharmaceutical industry faces significant challenges in maintaining the transparency and traceability of drugs throughout the supply chain, leading to issues such as counterfeit drugs and inefficiencies in drug distribution. This study proposes a blockchain-based drug supply chain management system designed to ensure enhanced transparency, traceability, and security. By integrating Hyperledger blockchain with IoT sensors and smart contracts, the system provides real-time tracking of drug shipments and automates key processes, reducing the risk of human error and improving compliance with regulatory standards. The proposed model was benchmarked against nine existing models, demonstrating superior performance across several key metrics. The model achieved an accuracy of 97.1%, the highest among the evaluated systems, indicating its robustness in detecting anomalies and maintaining data integrity. Additionally, the model exhibited the lowest energy consumption of 3.8 J/transaction and the highest data integrity score of 9.8. These results highlight the model's efficiency, scalability, and reliability, making it a promising solution for the pharmaceutical industry's supply chain challenges.
