Abstract
As anonymous peer-to-peer file sharing networks
transition from intellectual curiosity to societal real-
ity, their long-term viability is seriously threatened by
cheaters. A cheater either consumes resources without
producing them (a freeloader), or advertises valuable
content, but ultimately delivers that which is useless (a
spoofer). In both cases, the cheater realizes some ben-
efit from his actions without having to pay a commen-
surate cost. Because these networks are anonymous,
the traditional accountability mechanisms developed for
classic distributed systems do not apply.
In this paper we present a protocol that dramatically
reduces and in many cases eliminates the benefit gained
