Product Authenticity Verification System Using Blockchain

The growing prevalence of counterfeit products across global supply chains has posed unprecedentedthreats to consumer safety, regulatory compliance, and brand reputation. Existing verification measures,such as barcodes or holograms, have proven vulnerable to sophisticated forgery. This journal presents theProduct Authenticity Verification System (PAVS), a robust blockchain-powered solution to authenticateproducts using dynamic QR codes, RSA-based digital signatures, and decentralized ledger storage. PAVSenables real-time provenance verification by allowing stakeholders—manufacturers, retailers, andconsumers—to reliably check authenticity and product details directly from blockchain records. Throughan exploration of literature, system methodology, security mechanisms, and pilot outcomes, this articledemonstrates how PAVS reduces counterfeit incidents, enhances supply chain transparency, and paves theway for trust-centric, scalable, and interoperable anti-counterfeit solutions. Future enhancements, such asAI-based fraud detection and globalized smart contract workflows, are also discussed.
