The document describes IBM Food Trust, a blockchain-based food traceability system. It allows participants across the food supply chain to securely share information to track food products, mitigate contamination risks, reduce waste, and ensure freshness and quality. Key features include end-to-end traceability of products, easy verification of certifications through digitization of documents, and controlled data access so participants only see permissioned data. The system aims to involve millions of participants to gain visibility across global supply chains.
