Reputation systems to rate companies’ performances remain largely unexplored in research and are scarcely used in business-to-business (B2B) practice. Such systems are essential for businesses seeking trustworthy partners, as they help reduce information asymmetry, lower buyers' transaction risks, and allow high-quality service providers to justify premium pricing. Unlike traditional review-based systems in the business-to-consumer (B2C) context, we propose a B2B reputation mechanism in which buyers commit to a rating payment before a transaction. Once the buyer finalizes the rating, this payment is executed and recorded on a blockchain as an immutable, secure ledger. Our system mimics natural trust-building mechanisms with ratings that are (1) monetary-based, (2) stake-based, (3) non-aggregated, (4) involve counter-ratings, (5) selectively sellable, (6) individually comparable, (7) stored on a blockchain, (8) and monitored by a third instance. This system provides a novel approach to fostering trust in B2B transactions by reducing information asymmetry and transaction risk. We illustrate the mechanism’s application in the consulting sector. Our analysis has identified 23 institutional trust and distrust dimensions that promote establishing institutional trust through the proposed mechanism. Qualitative interviews suggest that, while complex and challenging to apply, this mechanism can foster trust in B2B transactions. Given the low maturity in the application domain—rating professional business services with business reputation systems—and solution domain—using monetary stakes for ratings, this system stands as a potential invention.

用于评估公司绩效的声誉系统在研究中基本上仍未得到探索，也很少用于企业对企业 （B2B） 实践。此类系统对于寻求值得信赖的合作伙伴的企业至关重要，因为它们有助于减少信息不对称，降低买家的交易风险，并允许高质量的服务提供商证明溢价的合理性。与企业对消费者 （B2C） 环境中基于评论的传统系统不同，我们提出了一种 B2B 声誉机制，在这种机制中，买方承诺在交易前支付评级。一旦买方最终确定评级，这笔付款就会被执行并记录在区块链上，作为不可变、安全的账本。我们的系统模仿自然的信任建立机制，其评级为 （1） 基于货币，（2） 基于权益，（3） 非汇总，（4） 涉及反评级，（5） 选择性可出售，（6） 单独可比，（7） 存储在区块链上，（8） 并由第三方监控。该系统通过减少信息不对称和交易风险，提供了一种新的方法来培养对 B2B 交易的信任。我们说明了该机制在咨询领域的应用。我们的分析确定了 23 个机构信任和不信任维度，这些维度通过拟议的机制促进了机构信任的建立。定性访谈表明，虽然应用复杂且具有挑战性，但这种机制可以培养对 B2B 交易的信任。鉴于应用领域（使用商业信誉系统对专业业务服务进行评级）和解决方案领域（使用货币利害关系进行评级）的成熟度较低，该系统有望成为一项发明 。
