Abstract: Counterfeit products pose significant financial losses and safety risks to consumers across various industries. Traditional anti-counterfeiting methods, such as visual markers and serial numbers, have proven inadequate in preventing fraud. This paper explores how blockchain technology can offer a more effective solution. By using blockchain’s decentralized ledger and cryptographic security, it creates a transparent and reliable record of every step in the supply chain. Unique product identifiers on this tamper-proof platform ensure accurate verification, building trust among consumers. Smart contracts within the blockchain ecosystem automate verification processes, reducing human error and making transactions more efficient. The proposed system involves registering manufacturers on the blockchain, assigning unique QR codes to products, and creating smart contracts for transferring product ownership. Consumers can verify product authenticity using a mobile app. The use of contract tools and cryptographic methods ensures the integrity and security of the data. This study highlights the potential of blockchain to enhance supply chain transparency, build consumer trust, and combat counterfeit products, ultimately fostering a safer and more transparent marketplace.
