FROM ORIGIN TO END: BLOCKCHAIN FOR SEAMLESS PRODUCT AUTHENTICATION AND OWNERSHIP VERIFICATION

Abstract

Counterfeiting poses a significant threat to global supply chains, undermining consumer trust, compromising public safety, and eroding brand value. Traditional methods such as serial number serialization and holograms, while tamper-resistant, require more robust, scalable solutions. This paper presents "Proof Point," a blockchain-based anti-counterfeiting system that leverages the Ethereum blockchain to ensure product authenticity and ownership tracking. By creating a decentralized, tamper-proof ledger, Proof Point enables real-time verification of product authenticity through QR codes linked to unique blockchain records. Smart contracts automate key processes such as product registration and ownership transfers, minimizing manual intervention and reducing fraud risks. To enhance performance, a local database stores metadata for fast and efficient access without dependency on external services. The decentralized architecture ensures secure tracking from manufacturers to end consumers, offering scalable applications across industries such as pharmaceuticals, electronics, and luxury goods. Although high transaction costs remain a challenge on Ethereum, future iterations aim to integrate cost-effective scaling solutions. Proof Point provides a transparent, reliable, and efficient mechanism for mitigating counterfeiting risks, fostering trust in supply chains, and supporting long-term resilience.
