Pinocchio: Incentives for honest participation in global-scale distributed trust management

In this paper, we introduce a framework for providing incentives for honest participation in global-scale distributed trust management infrastructures. Our approach is twofold: (1) we provide rewards for peers that advertise their experiences to others, and (2) impose the credible threat of halting the rewards, for a substantial amount of time, for participants who consistently provide suspicious feedback. For this purpose we develop an honesty metric which can indicate the accuracy of feedback.
