  abstract = {Reputation systems support trust formation in artificial
             societies by keeping track of the behavior of autonomous
             entities. In the absence of any commonly trusted entity, the
             reputation system has to be distributed to the autonomous
             entities themselves. They may cooperate by issuing
             recommendations of other entities' trustworthiness. At the time
             being, distributed reputation systems rely on plausibility for
             assessing the truthfulness and consistency of such
             recommendations. In this paper, we point out the limitations of
             such plausibility considerations and present an alternative
             concept that is based on evidences. The concept combines the
             strengths of non-repudiability and distributed reputation
             systems. We analyze the issues that are related to the issuance
             and gathering of evidences. In this regard, we identify four
             patterns of how evidence-awareness overcomes the limitations of
             plausibility considerations.}
