Can mutually mistrusting users collaborate in a distributed systems ? The answer is yes. See following papers.
2004 ACM Electronic Commerce: asynchronous trust system
This paper introduces the notion that Byzantine participants cannot bring down a recommendation system. It shows that honest peers can still successfully cooperate to retrieve the best value.
2005 IEEE ICDCS: concurrent trust system
2005 ACM-SIAM SODA: collaborative filtering
2005 ACM-SPAA Learning preferences by collaborating with strangers
This paper shows a randomized algorithm that successfully reconstructs all values even in presence of (majority) of byzantine peers.
