Reputation systems rely on historical information to account for uncertainty about users' intention to cooperate, but accumulating experience over long time periods is challenging in many situations. In peer-to-peer (P2P) systems, this operation is particularly hard due to churn—the continuous process of node arrival and departure. In this article, the authors examine the impact of churn on the perception of newcomers and identify the key factors that help uncertainty to decay slowly. The authors provide experimental results to illustrate the impact of churn on uncertainty reduction.
