A Blockchain Based Approach For Drug Traceability In Healthcare and Supply Chain

This paper presents the complete implementation of a custom blockchain-based system for drug tracea-bility in the healthcare supply chain. The system features an OTP-based verification mechanism to ensuresecure delivery to the correct patient. Built on a proprietary blockchain framework, it ensures transpar-ency, security, and protection against fraudulent activities. Performance evaluation highlights the system’sefficiency, scalability, and reliability. This research demonstrates how blockchain technology and secureverification methods can enhance trust and safety in healthcare logistics
