Cli-ents who have not worked with a particular consultancy face considerable risk when they place an order while lacking reliable information about the service quality they can expect. There is a strong link between trust and reputation, as the positive reputation of a consultancy can act as a substitute for a new client’s missing individual experience with the provider, fostering trust in the service quali-ty. Thus, creating, maintaining, and demonstrating a good reputation is of signifi-cant importance for consultancies in a very competitive industry.\r\nTo facilitate trustworthy signals, we design and implement a novel reputation mechanism that carries a monetary weight stored on a blockchain network as an immutable, decentralized, and transparent ledger. Based on an implementation in the Ethereum network and subsequent evaluation, we conclude that the reputation mechanism can contribute to leveling information asymmetry and reducing risk while increasing reputation and trust. The mechanism lends itself to being used in other business-to-business scenarios that suffer from similar information asymmetries."}],"status":"public"},{"date_created":"2025-05-28T08:12:28Z","publisher":"Springer","title":"Blockchain‑based reputation systemsfor business‑to‑business services: designing a reputation mechanism to reduce information asymmetry in professional consulting","issue":"1","quality_controlled":"1","year":"2025","external_id":{"unknown":["https://doi.org/10.1007/s10257-025-00702-9"]},"language":[{"iso":"eng"}],"ddc":["000"],"keyword":["Information asymmetry","Trust","Reputation system","Monetary rating","Blockchain","Consulting"],"publication":"Information Systems and e-Business Management","file":[{"content_type":"application/pdf","relation":"main_file","success":1,"creator":"hemmrich","date_created":"2025-05-28T08:05:18Z","date_updated":"2025-05-28T08:05:18Z","file_name":"Hemmrich_et_al-2025-Information_Systems_and_e-Business_Management.pdf","access_level":"closed","file_id":"60051","file_size":1440251}],"abstract":[{"lang":"eng","text":"Reputation systems to rate companies’ performances remain largely unexplored inresearch and are scarcely used in business-to-business (B2B) practice. Such systemsare essential for businesses seeking trustworthy partners, as they help reduce infor-mation asymmetry, lower buyers’ transaction risks, and allow high-quality serviceproviders to justify premium pricing. Unlike traditional review-based systems in thebusiness-to-consumer (B2C) context, we propose a B2B reputation mechanism inwhich buyers commit to a rating payment before a transaction. Once the buyer final-izes the rating, this payment is executed and recorded on a blockchain as an immu-table, secure ledger. Our system mimics natural trust-building mechanisms with rat-ings that are (1) monetary-based, (2) stake-based, (3) non-aggregated, (4) involvecounter-ratings, (5) selectively sellable, (6) individually comparable, (7) stored ona blockchain, (8) and monitored by a third instance. This system provides a novelapproach to fostering trust in B2B transactions by reducing information asymme-try and transaction risk. We illustrate the mechanism’s application in the consultingsector. Our analysis has identified 23 institutional trust and distrust dimensions thatpromote establishing institutional trust through the proposed mechanism. Qualita-tive interviews suggest that, while complex and challenging to apply, this mecha-nism can foster trust in B2B transactions. Given the low maturity in the applicationdomain—rating professional business services with business reputation systems—and solution domain—using monetary stakes for ratings, this system stands as apotential invention."}],"author":[{"first_name":"Simon","full_name":"Hemmrich, Simon","id":"83557","last_name":"Hemmrich"},{"last_name":"Nissen","full_name":"Nissen, Volker","first_name":"Volker"},{"first_name":"Daniel","last_name":"Beverungen","full_name":"Beverungen, Daniel","id":"59677"},{"full_name":"Pauls, Josias Daniel Miño","last_name":"Pauls","first_name":"Josias Daniel Miño"}],"volume":23,"oa":"1","date_updated":"2026-04-02T04:32:13Z","main_file_link":[{"url":"https://link.springer.com/epdf/10.1007/s10257-025-00702-9?sharing_token=fOiWqZx_ScKFAKjxu5UqWPe4RwlQNchNByi7wbcMAY6mjxpZFPB3OtpVT0rAZf9eEBt3_qXIVcZ67l3R9JVYasmuCsIimzE-xfP0N5Rimun248j0jFOnL1eBu4rypKSDFnbmR3kJ5xx-HLnCXvPvQPwpm09qOkS9GSNsiG-du60%3D","open_access":"1"}],"doi":"https://doi.org/10.1007/s10257-025-00702-9","publication_status":"published","has_accepted_license":"1","citation":{"ama":"Hemmrich S, Nissen V, Beverungen D, Pauls JDM.

However, these systems are relevant for prospective buyers to find a trustworthy seller. This observation applies especially to short-lived business relationships where fulfilling the performance promise is subject to a high degree of uncertainty. This paper explores the value of a reputation system for a business-to-business (B2B) context and focuses on three novel solutions for designing reputation systems. These solutions include selling ratings, conducting ratings as payments, and employing a counter-rating mechanism. We interview buyers to fathom the added value of these solutions in different contexts. Our findings suggest that such a system is useful for companies acting in less transparent markets and also helps when companies already have a good market overview. Depending on the market conditions and business context, the perceived value of the proposed system varies.","lang":"eng"}],"author":[{"first_name":"Simon","last_name":"Hemmrich","id":"83557","full_name":"Hemmrich, Simon"},{"first_name":"Jannika Marie","last_name":"Schäfer","id":"74374","full_name":"Schäfer, Jannika Marie"},{"last_name":"Hansmeier","id":"55603","full_name":"Hansmeier, Philipp","first_name":"Philipp"},{"last_name":"Beverungen","id":"59677","full_name":"Beverungen, Daniel","first_name":"Daniel"}],"date_created":"2024-06-27T09:52:26Z","date_updated":"2024-06-27T10:01:29Z","conference":{"end_date":"2024-01-06","location":"Honolulu","name":"Hawaii International Conference on System Sciences 2024","start_date":"2024-01-03"},"main_file_link":[{"url":"https://www.researchgate.net/profile/Simon-Hemmrich-3/publication/374550987_The_Value_of_Reputation_Systems_in_Business_Contexts_-A_Qualitative_Study_Taking_the_View_of_Buyers/links/652406723ab6cb4ec6d01951/The-Value-of-Reputation-Systems-in-Business-Contexts-A-Qualitative-Study-Taking-the-View-of-Buyers.pdf"}],"title":"The Value of Reputation Systems in Business Contexts–A Qualitative Study Taking the View of Buyers","publication_status":"published","citation":{"short":"S.

While IS research has investigated reputation systems mainly\r\nas review systems on online platforms for business-to-consumer (B2C) transactions, no proper solutions\r\nhave been developed for business-to-business (B2B) transactions yet. We use blockchain technology to\r\npropose a new class of reputation systems that apply ratings as voluntary bonus payments: Before a\r\ntransaction is performed, customers commit to pay a bonus that is granted if a service provider has\r\nperformed a service properly. As opposed to rival reputation systems that build on cumulated ratings\r\nor reviews, our system enables monetized reputation mechanisms that are inextricably linked with online\r\ntransactions. We expect this system class to provide more trustworthy ratings, which might reduce\r\nagency costs and serve quality providers to establish a reputation towards new customers, building on\r\nsecond-order trust.","lang":"eng"}],"status":"public","_id":"49785","user_id":"83557","keyword":["Trust","Risk","Reputation System","Blockchain Technology","Business Reputation System."],"language":[{"iso":"eng"}]},{"date_created":"2023-05-16T08:31:27Z","author":[{"first_name":"Simon","id":"83557","full_name":"Hemmrich, Simon","last_name":"Hemmrich"},{"last_name":"Bobolz","full_name":"Bobolz, Jan","id":"27207","first_name":"Jan"},{"first_name":"Daniel","last_name":"Beverungen","id":"59677","full_name":"Beverungen, Daniel"},{"last_name":"Blömer","full_name":"Blömer, Johannes","id":"23","first_name":"Johannes"}],"date_updated":"2023-05-23T10:12:32Z","conference":{"name":"ECIS 2023"},"main_file_link":[{"url":"https://aisel.aisnet.org/ecis2023_rp/344"}],"title":"Designing Business Reputation Ecosystems — A Method for Issuing and Trading Monetary Ratings on a Blockchain","has_accepted_license":"1","citation":{"ieee":"S.

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."}]}]
