    A Blockchain Research Framework
    (Business & Information Systems Engineering: Vol. 59, No. 6, 2017) Risius, Marten; Spohrer, Kai
    While blockchain technology is commonly considered potentially disruptive in various regards, there is a lack of understanding where and how blockchain technology is effectively applicable and where it has mentionable practical effects. This issue has given rise to critical voices that judge the technology as over-hyped. Against this backdrop, this study adapts an established research framework to structure the insights of the current body of research on blockchain technology, outline the present research scope as well as disregarded topics, and sketch out multidisciplinary research approaches. The framework differentiates three groups of activities (design and features, measurement and value, management and organization) at four levels of analysis (users and society, intermediaries, platforms, firms and industry). The review shows that research has predominantly focused on technological questions of design and features, while neglecting application, value creation, and governance. In order to foster substantial blockchain research that addresses meaningful questions, this study identifies several avenues for future studies. Given the breadth of open questions, it shows where research can benefit from multidisciplinary collaborations and presents data sources as starting points for empirical investigations.

    Auswahlprozess zur Identifikation von Einsatzmöglichkeiten für Blockchain-Technologie
    (HMD Praxis der Wirtschaftsinformatik: Vol. 55, No. 6, 2018) Werner, Johannes; Mandel, Peter; Theilig, Max; Zarnekow, Rüdiger
    Die Blockchain-Technologie steht derzeit verstärkt im Fokus der Öffentlichkeit. Neben dem Einsatz als Kryptowährung wird der Einsatz dieser relativ jungen Technologie auch in Unternehmen betrachtet. Die dadurch entstehenden Angebote können etablierte Unternehmen herausfordern, bspw. durch Effizienzsteigerung oder neue Geschäftsmodelle. Daher stellt sich die Frage, ob der Einsatz von Blockchain-Technologie auch im eigenen Unternehmen sinnvoll ist um den technologischen Anschluss an Konkurrenten nicht zu verlieren. Dieser Frage vorgelagert müssen Einsatzszenarien für Blockchain-Technologie identifiziert und entsprechend bewertet werden. In diesem Artikel wird der Auswahlprozess für Einsatzszenarien am Praxisbeispiel eines Energienetzbetreibers betrachtet. Hierfür wird zunächst die Problemstellung konkretisiert und ein Überblick über Entscheidungsmodelle zum Einsatz von Blockchain gegeben. Anschließend wird das Beispielunternehmen und seine Ausgangssituation beschrieben sowie der durchgeführte Auswahlprozess dargestellt. Der dabei ausgewählte Anwendungsfall wird auf seine Verbesserungspotentiale durch Blockchain betrachtet und die Konzeption für den Einsatz wird vorgestellt. Abschließend werden Handlungsempfehlungen für den Umgang mit der Blockchain-Technologie in Unternehmen gegeben. The blockchain technology currently attracts a lot of attention. Apart from its application for cryptocurrencies, business application of this technology are emerging. These may lead to increasing efficiencies or business model innovations, to which established companies must react. For not falling behind the technological level of competitors, the question of using this technology in companies arises. First, operational scenarios for blockchain technology must be identified and evaluated. In this article the selection process of application scenarios for blockchain technology is shown by an example of an energy grid provider. Therefore, the problem itself and a review of different decision models for the use of blockchain technology are presented. Afterwards, the case company, its initial situation and the used selection process are described. The chosen use case is analyzed regarding its possible improvements by employing blockchain technology and a concept for the implementation is presented. Furthermore, recommendations for dealing with blockchain technology in companies are given.

    The Energy Consumption of Blockchain Technology: Beyond Myth
    (Business & Information Systems Engineering: Vol. 62, No. 6, 2020) Sedlmeir, Johannes; Buhl, Hans Ulrich; Fridgen, Gilbert; Keller, Robert
    When talking about blockchain technology in academia, business, and society, frequently generalizations are still heared about its – supposedly inherent – enormous energy consumption. This perception inevitably raises concerns about the further adoption of blockchain technology, a fact that inhibits rapid uptake of what is widely considered to be a groundbreaking and disruptive innovation. However, blockchain technology is far from homogeneous, meaning that blanket statements about its energy consumption should be reviewed with care. The article is meant to bring clarity to the topic in a holistic fashion, looking beyond claims regarding the energy consumption of Bitcoin, which have, so far, dominated the discussion.
