Abstract: The emergence of fake products in various global supply chains causes significant economic, brand reputation, and safety implications to occur. This paper offers an innovative blockchain-enabled transparency solution for tracking the flow of goods and their authenticity using Hyperledger Fabric and InterPlanetary File System (IPFS). As opposed to the use of a centralized database approach, the architecture of the proposed system is based on smart contracts to verify the genuineness of all operations during the logistics journey, including sourcing the raw material up to reaching the point of sale. The method involves the application of hashes for products by combining the use of QR-NFT hybrid and consensus protocols. Quantitative analysis of the tested system resulted in a detection rate of 99.8%, reducing verification latency by 78% compared to other legacy solutions, and enabling instant tracing for 10,000 nodes within a second.
