Digital Power of Attorney catalyzed by Software Requirements for Blockchain-based Applications
(2022)
Blockchain Technology (BT) with so-called web3 is at an inflection point between new sub-theme hypes and world-wide industrialization over last three years thanks to large companies like MicroStrategy [1], Facebook [2] and several Venture-Capital formations [3] who are already fighting over market share and community growth. Our work represents insights from Literature-based Software Requirement (SR) elicitation for a specific Blockchain-based Application, which is creation, managing and control of digital Power of Attorney (POA). The context of POA is not only a financial driven use-case it is by far a heavy weight universal legal transaction. We use a morphological box and reduced PRIMS-P to synthesis a generic specification for further Blockchain-based Application development. Formulated SRs in POA context are reflected on our core actors which are Grantor and authorized, trusted, external Entities. Proposed characteristics for relationship and effects are visualized in a reference model originally used in digital platform ecosystems [4]. This design and modelling approach facilitated closing discussion of BT and its future eCommerce perspective.
Abstract: Blockchain Technology has become an innovative, mature tool for digital transformation, disrupting more and more application areas in their business processes, values, or even economic models. This paper leverages more than 30 academic publications on prototypes and their Blockchain-based use cases to transact certificates in the context of public education. The conceptual design and guiding ideas are reflected in the practical application development for the Federal Ministry of Education and Research ECHT! project within the showcase region WIR! in Mittweida and are used for the research design. During this approach we applied agile methods and the current certificate process to propose a comprehensive disclosure of a new software prototype including a three-layered architecture with multi-stakeholder components. The artefact instantiation contributes to the practical knowledge base within Information System Research and specifically in digital certificate processes starting from creation, searching, and proofing up to revoking by consideration of an existing IT landscape as well as organizational hierarchy.
