Blockchain has been proposed to support supply chain use cases due to its numerous properties, such as transparency, immutability, and auditability. For simple scenarios, such as asset ownership transfer, these solutions work well. However, in cases where exchanged components are further used in manufacturing processes to produce refined items, which then serve as the basis for other products, maintaining traceability while enforcing specific business rules becomes a challenge. Tracking and transforming physical goods also present trust issues regarding the actual existence of the goods and the conditions of the transformation processes, such as temperature or precise location. In this paper, we present BC24, a smart supply chain model that leverages blockchain and RFID to support asset, process, and environmental traceability. We validate our model through a real industrial use case in an agro-food supply chain specializing in meat processing.
