Abstract- A drug traceability system is needed to protect public health and aid pharmaceutical companies by tracking the drug movement in the supply chain. The system provides the means to monitor where a drug has been and where it is going, helping to protect the integrity of the pharmaceutical supply chain while preventing counterfeit products. Such demands are hardly met by traditional centralized server-client architectures, which in turn fail to address the core problems of data integrity, privacy, resilience, and adaptability while leaving significant gaps in security and operational efficiency.
In response to these drawbacks, we propose an advanced and unique blockchain-based approach with Ethereum technology and smart contracts. This system facilitation provides a secure, scalable, and tamper-proof structure for end-to-end drug traceability. The use of decentralized off-chain storage and the negation of the need for intermediaries will both reduce operational inefficiency and enhance transparency and trust throughout the drug-supply chain. Smart contracts make sure that rules and transactions are executed automatically, consistently, and in a reliable way, thus upholding data authenticity and privacy. One of the innovations of this system lies in its efficient storage pruning mechanism that enables prudent data management to foster stable and sustainable blockchain. Such a facility combined with immutable record-keeping and enhanced data provenance presents a daunting means for mitigating the risk of counterfeit drugs. Transparency and verifiability across the system present a transformative proposition for ensuring regulatory compliance, public safety, and enabling trust among all its stakeholders, namely manufacturers, distributors, regulators, and consumers.
