  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 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.
