Securing the Supply Chain A Blockchain Based Anti Counterfeiting Framework

Counterfeiting is a major problem in the antique industry, making it difficult to verify whether an item is genuine. This paper introduces a blockchain-based system that helps secure the antique supply chain by making all item records permanent and easy to trace. Each antique is registered on a blockchain with a unique ID, including details like images, ownership history, and location. A QR code is created for each item so that anyone can quickly check its authenticity. The use of blockchain technology ensures that the data cannot be changed, increasing trust between buyers, sellers, and other parties. A React.js-based interface has been developed to allow easy item registration, image uploading, and real-time location tracking, supported by a secure backend. Tests and evaluations show that this system can effectively reduce counterfeiting by improving the transparency and security of the antique supply chain.
