In this paper, we discuss problems found with the incentive model in a large, deployed peertopeer network, Maze. We evaluate several alternatives, and propose an incentive system that generates preferences for wellbehaved nodes while correctly punishing colluders. We discuss our proposal as a hybrid between TitforTat and EigenTrust, and show its effectiveness through simulation of real traces of theMaze system.}, url = {http://approjects.co.za/?big=en-us/research/publication/robust-incentives-via-multi-level-tit-for-tat/}, }
