A Blockchain-Based Traceability System in Agri-Food SME: Case Study of a Traditional Bakery

In this paper we present a blockchain based system for the supply chain management of particular Italian bread. Goal is to guarantee transparent and auditable traceability Carasau bread where each actor can verify quality products conformity normative about hygienic-sanitary conditions along chain. To realize relied on Blockchain Internet Thing technologies in order provide trustless environment, which trust placed cryptography, mathematical operations network, not public or private companies. Thanks use digital aims reduce data entry errors risk tampering. Our designed so that chain, nodes equipped with several sensors directly communicate their Raspberry Pi units elaborate transmit them Interplanetary File System Ethereum Blockchain. Furthermore, ad hoc Radio Frequency Identification Near Field communication tags shortly proposed information batches. The dedicated RFID robustness during on-bread operation was numerically tested. will easily allow end consumers have view whole journey from raw material purchased final product supervisory authority perform online inspections products’ good working practices.
