This paper proposes a generic agri-food supply chain traceability system based on blockchain technology implementing the "from-farm-to-fork" (F2F) model currently used in the European Union, which can integrate current traceability rules and processes. The proposed system allows the consumer to reconstruct the product history up to the origin in order to verify product health and quality by simple QR code scan. The blockchain chosen for this purpose is Hyperledger Sawtooth, issued with writing permissions and rules to guarantee access only to members recognized as legitimate participants in the process. The whole system has been realized according to an agile methodology (ABCDE), recently devised for designing a general blockchain system with software engineering practices by mean of User Stories and UML diagrams, in order to obtain a higher software quality. All of the involved operators are able to identify any participants along the entire supply chain, increasing the degree of trust between organizations and individuals, with autonomous management of temporal sequence of activities.
