Abstract: While traceability has become an important aspect in managing safety-sensitive supply chains, blockchain arose as an innovative technology with great application potentials in this area. This research determines the requirements of the main stakeholders along the supply chain from agriculture to retail with regard to a blockchain-based traceability system. The resulting specification framework includes usage requirements formulated as data classes, technical requirements regarding data access, storage and processing, and interoperability requirements necessary to assure digital communication and permanent operability. General application guidelines for digital information systems are derived, and the blockchain technology is evaluated with regard to applicability. A distinction between public and sensitive data appears to be fundamental, while a two-part architecture involving a public permissioned blockchain network is proposed as a basis for a digital traceability system in the food industry.
