  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."
