Counterfeiting significantly impacts product manufacturing, damaging brand reputation and profitability. Blockchain technology offers a secure solution for product authentication by creating a distributed and immutable ledger of product information. This project proposes a system leveraging Quick Response (QR) codes linked to a blockchain to combat counterfeiting. By scanning a product's QR code, users can instantly verify its authenticity against the blockchain record, eliminating reliance on third-party verification and receiving immediate notification of genuine or fake products.
