        abstract = {Counterfeit products have become a major problem affecting customers and industries. The existing systems use static QR codes for product verification, which can be easily copied or misused. To overcome this, our project proposes a Smart Product Authentication System using Blockchain that ensures secure and tamper-proof verification of products. In this system, every product is registered on the blockchain network with a dynamic QR code and an NFC tag. The dynamic QR changes with each transaction, preventing duplication, while the NFC tag provides additional security through chip-based authentication. When the customer scans the QR or taps the NFC tag, the system verifies the product details stored on the blockchain, ensuring transparency and authenticity. This method builds trust between manufacturers and consumers by providing a secure and decentralized way to identify genuine products and eliminate fake ones.},
