Blockchain in Agri-Food Traceability Systems: A Model Proposal for a Typical Italian Food Product

Controlling the product quality in food industry throughout its supply chain is today one of the most challenges in the world especially when it comes to typical food products. In recent years, various companies are trying to experiment with joint use of Blockchain and Radio Frequency Identification technologies to solve problems in scenarios where numerous untrusted actors get involved. Blockchain is gaining increasing popularity as a technology to enable product traceability in a certified and immutable way from the farm to the fork of food products and to avoid fraud and counterfeiting by guaranteeing trusted, transparent and shared information in the agri-food supply-chain. By combining smart contracts, Interplanetary File System and Internet of Things technologies, this paper tries to address these issues and presents a proposal of an implementation model for the supply chain management of a typical Italian food product - Carasau bread. The main goal of the model proposal is to guarantee and certify a transparent, secure and auditable traceability in such a way each actor of the supply chain can verify the quality of the product.
