An Open and Fully Decentralised Platform for Safe Food Traceability

This paper proposes a blockchain-based food safety traceability platform designed to improve transparency, accountability, and trust across the food supply chain. Traditional traceability systems often face challenges such as data tampering, limited visibility, and leakage of sensitive information. To address these issues, the platform integrates blockchain technology with the InterPlanetary File System (IPFS), enabling secure, decentralized, and immutable storage of supply chain records. The system captures transactions and activities across production, processing, transportation, warehousing, and sales in real time. Leveraging smart contracts and consensus mechanisms, the platform provides reliable traceability while remaining adaptable to different food products and broader supply chain contexts. Simulation results demonstrate successful blockchain transactions and strong real-time responsiveness across the platform.
