Counterfeit products pose a serious threat to global supply chains, resulting in economic losses, brand
reputation damage, and consumer safety risks. Traditional centralized authentication systems are
vulnerable to data tampering, lack transparency, and fail to provide end-to-end traceability. This paper
proposes a blockchain-based product authentication framework that ensures secure, transparent, and
tamper-proof tracking of products across the supply chain. The system integrates QR-code tagging,
smart contracts, distributed ledger technology, and decentralized verification mechanisms to prevent
counterfeit infiltration. Experimental evaluation demonstrates improved traceability accuracy, reduced
verification time, and enhanced trust among stakeholders compared to conventional centralized
databases. The proposed framework provides a scalable and secure solution for real-time product
verification and counterfeit elimination.
