Abstract

Abstract: - This work describes the functioning of blockchain technology, its potential use or impact on current supply chain management (SCM) registry systems, and the role of legal experts. Fake products have emerged as a major global issue, leading customers to purchase fraudulent goods without any means to verify their authenticity. This system utilizes blockchain technology to counteract the auctioning of counterfeit products. We utilize blockchain technology to enable producers or creators to incorporate verifiable product serial numbers into the balance sheet, which customers can use to confirm the authenticity of the product before making a purchase. Blockchain ensures the integrity of data, fostering a trustworthy environment. The proposed system uses a custom algorithm, which helps to identify fake products. This approach primarily focuses on generating QR-codes for individual accounts and utilizing Supply Chain Management (SCM) to ensure secure data distribution to end users. Keywords: Blockchain, Smart contracts, PHR (Personal Health Records), healthcare, access control.
