    Touching space: distributed ledger technology for tracking and tracing certificates
    (2023) Moriggl, Pascal; Asprion, Petra; Schneider, Bettina; Scherb, Christopher; Bui, Tung X. [in: Proceedings of the 56th Hawaii International Conference on System Sciences]
    Components built into space vehicles and equipment (space products) must meet different regulatory requirements; in detail, each component must be certified and sustainably traceable at all times. Space engineers have expressed the need for an interoperable system to collect, manage and route certifications for components, parts and materials that go into space products. The lack of a unified approach in the European space industry is a challenge for companies involved in product development. This research proposes an open-source, secure, fast and distributed ledger technology (DLT) based solution that fits into any IT environment and is well adapted to the needs of manufacturing companies in the space sector. The results show that a blockchain-based solution based on ‘Hyperledger Fabric’ combined with the InterPlanetary File System is viable. The results can guide other researchers and practitioners to consider DLTs when changing their certification management paradigm with suppliers, customers and auditors.

    Towards a distributed ledger system for supply chains
    (2019) Asprion, Petra; Hübner, Philipp; Moriggl, Pascal; Bui, Tung X. [in: Proceedings of the 52nd Hawaii International Conference on System Sciences]
    Interoperability and traceability of digital supply chains are becoming a major competitive factor. Businesses operating in supply chains need to share interoperable information and systematically track product and service deliveries. This research investigates a novel approach to model digital supply chains and operationalizes this through a "Distributed Ledger System" in combination with "Smart Contracts". Based on design science, relevance and rigor for a novel approach are derived. As resulting ‘artifacts’, exemplary supply chains using colored Petri-nets are modeled as a structured and automatable instance for the sketched ‘Token-flow Supply Chains’. For the operation of our visionary scenario, a baseline concept with an associated architecture is drafted. We argue that the outlined approach and related artifacts are predestined to achieve a new quality of performance and innovation including bridging the current challenges for digital supply chains.
