  text: "Trust between client and consultant is perhaps the most important asset in
    con-sulting, as this is a highly intangible knowledge-intensive business that
    concerns is-sues of outstanding strategic and operational importance for the customers.
    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."

  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.

  text: Reputation systems for companies to rate each other's performance are largely
    unexplored in research and hardly available in practice. 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.

  text: "Reputation is indispensable for online business since it supports customers
    in their buying decisions and\r\nallows sellers to justify premium prices. 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."

  text: Market transactions are subject to information asymmetry about the delivered
    value proposition, causing transaction costs and adverse market effects among
    buyers and sellers. 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.
