Counterfeit products are a major problem in modern supply chains and cause financial loss, brand damage, and safety risks to consumers. Traditional centralized systems are not secure and can be easily modified or attacked. To overcome these issues, this paper proposes a custom blockchain-based decentralized system for anti-counterfeit product authentication in IoT-integrated supply chains. Each product is registered by the supplier and assigned a unique QR code. Product information is secured using SHA-256 hash generation and stored in a custom blockchain network. The company module verifies product movement, while end users can scan QR codes to check product authenticity in real time. If any mismatch is found, the system alerts users about possible counterfeit products. The proposed system improves transparency, data security, and trust among supply chain participants and provides an effective solution for counterfeit detection.
