Abstract
This study describes a blockchain-based strategy to improving traceability in the pharmaceutical supply chain, with the goal of combating counterfeit pharmaceuticals and increasing product legitimacy. The suggested approach removes middlemen, guarantees data provenance, and gives users a safe, unchangeable transaction history by utilizing smart contracts and decentralized storage. Centralized control, a lack of information, and complicated stakeholder behavior make it difficult to track products effectively in a healthcare supply chain that includes raw material suppliers, manufacturers, distributors, pharmacies, hospitals, and patients. This intricacy makes it easier for counterfeit medications to infiltrate, which the World Health Organization reports are a major cause of death, especially for children, and make up as much as 30% of medications sold in developing nations. Additionally, counterfeit medications cause the pharmaceutical industry to suffer significant financial losses. The proposed method offers a distributed and easily accessible way to keep an eye on every phase of the medication supply chain by introducing a smart contract architecture that verifies data provenance, traceability, and immutability. We describe the entity-relation diagram, operational algorithms, and architecture of the smart contract system in detail and verify that it is effective in enhancing supply chain transparency. As evidenced by our findings, this blockchain framework provides a general, scalable approach for secure traceability that can be applied to a variety of pharmaceuticals supply chains, helping to create a reliable, impenetrable drug tracking and verification system.
