    Together or Not? Exploring Stakeholders in Public and Permissionless Blockchains
    ( 2022-01-04) Schmid, Roman ; Ziolkowski, Rafael ; Schwabe, Gerhard
    The emergence of blockchain projects enables new ways of collaboration between untrusted parties. Each of these projects, however , only exists because stakeholders of these projects find common ground. If this common ground is not found, blockchains are forked – organizationally and technically – which endangered major blockchain systems like Bitcoin or Ethereum. To assure the operation of such projects and, thus, to improve their governance, it is crucial to understand their stakeholders. This research conducted a literature review and a survey to (1) identify blockchain stakeholders and to (2) understand their interests as well as underlying motives for their interests. This research has two main contributions: a stakeholder map, which serves as a lens to study stakeholders of public blockchains, and exemplary insights from the application of this lens comprising of 74 survey responses. Consequently, this research provides a novel tool for stakeholder analysis in academia and practice to improve blockchain governance.

    The Proliferation of End Users as a Success Metric for Cryptocurrencies
    ( 2022-01-04) De Rossi, Leonardo Maria ; Avital, Michel ; Gleasure, Rob
    Over the last decade, numerous studies have examined the remarkable appreciation of cryptocurrencies and have typically focused on their price and the factors that predict them. In contrast, this paper argues that the success of a cryptocurrency is determined not only by its monetary value but also by the proliferation of its end users. Specifically, we hypothesize that changes in developers’ and miners’ activities drive the growing proliferation of a cryptocurrency’s end users. Building on the Bitcoin case, we use a time-series model based on 4,285 Bitcoin daily observations to suggest that changes in the number of end users are anticipated by surges or drops in activity by the developers and miners who develop and maintain the network. We further find a limited relationship between these variables and the price of Bitcoin. These results support an alternative view of cryptocurrencies’ success and highlight further research avenues in this nascent domain.

    The De-Central Bank in Decentralized Finance: A Case Study of MakerDAO
    ( 2022-01-04) Brennecke, Martin ; Guggenberger, Tobias ; Schellinger, Benjamin ; Urbach, Nils
    Countless decentralized finance (DeFi) applications of the past years have suffered from the high volatility and speculative behavior surrounding their underlying crypto assets. While the academic debate has been flourishing in these areas, Decentralized Autonomous Organizations (DAOs) have not received as much attention. This is the case even though they could offer an opportunity to solve some of the underlying problems of existing cryptocurrencies and ecosystems, for example, by providing lower volatility and, thus, exchange rate stability. This paper presents an economic analysis of the MakerDAO, a DAO in DeFi. In doing so, we use a single case study methodology based on existing resources and expert interviews. It also uses monetary theory instruments to provide researchers and developers with insights into how DAOs are governed. Further, it serves to illustrate how IS research may support the development of future IT artifacts aimed at offering the infrastructure for DeFi applications.

    Increasing user engagement on blockchain applications through persuasive design
    ( 2022-01-04) Knott, Manuel ; Mayer, Anne-Sophie ; Strich, Franz ; Fiedler, Marina
    Blockchain gives rise to many new applications and use cases and has already markedly changed several industries, such as financial services, energy and utilities, or healthcare. Although blockchain could potentially be used disruptively for end-user applications as well, utilizing it remains poor. It appears that the unconvincing design of many end-user blockchain applications leads to insufficient user engagement. To investigate the influence of design aspects on users’ engagement of blockchain end-user applications, we developed a blockchain application for the creative industries based on the principles of persuasive design. Hereby, we aim to contribute to research in the blockchain context on how end-user applications need to be designed to increase user engagement. By using a design science research process, we can ultimately provide a total of seven recommendations for developing persuasive blockchain applications for end-users.

    Going Beyond Blockchain Adoption's Hype to Improve Supply Chain Sustainability: Evidence From Empirical and Modelling Studies
    ( 2022-01-04) Chikhi, Tinhinane ; Santa-Eulalia, Luis Antonio ; Mosconi, Elaine ; Risso, Lucas Antonio ; Filho, Moacir Godinho ; Ganga, Gilberto Miller Devós
    Potential solutions emerge with the fourth Industrial Revolution technologies, including the Internet of Things, Artificial Intelligence and Blockchain. The global supply chain requires greater traceability and transparency to ensure product security, efficient management and sustainable performance. However, traditional supply chains face several challenges related to traceability systems. This paper aims to analyse academic literature regarding Blockchain adoption in supply chains to improve traceability and transparency from a sustainable perspective. A systematic literature review was performed in order to provide verifiable evidence; we focused our investigation on empirical and modelling articles. Results suggest that Blockchain benefits occur through three levels: macro-level (overall supply chain network), meso-level (such as dyadic relationships) and micro-level (end consumers). However, we note that the contribution’s results have not yet reached a consensus. We have therefore proposed three research insights towards addressing the identified gaps.
