Crosschecking Verification Over the Ethereum Blockchain Using QR Scannable Products

Counterfeit products pose a significant threat to global economies, undermining consumer trust and damaging brand reputations. Traditional verification methods often prove ineffective in combating the proliferation of counterfeit goods. This research explores the integration of QR codes and Ethereum blockchain technology to enhance product verification within supply chains, offering a more secure and transparent solution. The proposed research aims to foster trust, transparency, and consumer confidence by generating unique QR codes linked to digital counterparts on the blockchain. The system enables dynamic interactions between consumers and the authentication process through a user-friendly mobile interface, where QR codes serve as secure anchors for product information verified against blockchain entries. The research encompasses the development of smart contracts, a user-friendly interface, and comprehensive testing to ensure the system’s scalability and reliability. Overall, this research demonstrates the potential of combining QR codes and blockchain technology to revolutionise product verification within supply chains, providing a more secure, efficient, and reliable means of combating counterfeiting.
