Information systems research has investigated how review systems can reduce information asymmetry in business-to-consumer markets. However, these systems cannot be readily applied to business-to-business markets, are vulnerable to manipulation, and suffer from conceptual weak spots since they use textual data or star ratings. Building on design science research, we conceptualize a new class of reputation systems based on monetary-based payments as quantitative ratings for each transaction stored on a blockchain. Using cryptography, we show that our system assures content confidentiality so that buyers can share and sell their ratings selectively, establishing a reputation ecosystem. Our prescriptive insights advance the design of reputation systems and offer new paths to understanding the antecedents, dynamics, and consequences to reduce information asymmetry in B2B transactions. https://ris.uni-paderborn.de/download/44855/45209/A_Blockchain_Based_Reputation_Ecosystem_for_Business___Payments_as_Ratings.pdf application/pdf 2023 eng yes Hemmrich, Simon, et al. “Designing Business Reputation Ecosystems — A Method for Issuing and Trading Monetary Ratings on a Blockchain.” <i>ECIS 2023 Research Papers</i>, 2023. @inproceedings{Hemmrich_Bobolz_Beverungen_Blömer_2023, title={Designing Business Reputation Ecosystems — A Method for Issuing and Trading Monetary Ratings on a Blockchain}, booktitle={ECIS 2023 Research Papers}, author={Hemmrich, Simon and Bobolz, Jan and Beverungen, Daniel and Blömer, Johannes}, year={2023} } Hemmrich S, Bobolz J, Beverungen D, Blömer J.
