Abstract

Blockchain is a radical innovation with a core value proposition of shifting trust from institutions towards algorithms. Still, the potential of Blockchains remains vague due to the knowledge gap between computer science and socio-economic activities. Ninety percent of current Blockchain projects did not move from ideas to production-ready prototypes. Researchers and practitioners are searching for the meaningful leveraging of Blockchains for value creation. This dissertation aims to bridge the gap between technical and managerial knowledge of Blockchain that allows successful Blockchain system design and implementation. Therefore, the objective of the project is to identify the scope of Blockchain applications and introduce guidelines to make purposeful decisions of Blockchain implementations. The dissertation project covers four research questions. First, I consolidated knowledge of Blockchain technical configurations through the development of a taxonomy. Second, I considered the design patterns of smart contracts that represent the application logic of Blockchain systems. Third, I offered guidance for transforming initial conceptions of Blockchain ideas into working system prototypes by introducing a Blockchain configuration process model. Fourth, I investigated the common factors of Blockchain decisions to evaluate Blockchain implementations in the form of the framework. I employed a Design Science Research approach to developing four artefacts. The first three artefacts consider technical, application, and organizational aspects of Blockchain. The synergy reflects in the fourth, combinational artefact, which employs the high-level factors of Blockchain decisions. During the project, I have investigated the scientific and business studies, run Blockchain-based applications, conduct interviews, and evaluate the findings on Blockchain projects. The dissertation project contributes to research by bridging knowledge gaps between computer science and socio-economic research on a Blockchain that provides a fruitful ground for future conceptual and empirical studies. For practitioners, the developed artefacts are useful to identify and guide Blockchain projects that facilitate purposeful Blockchain adoption.
