An independent reputation system for P2P networks

Reputation is a very sensitive and important component in Peer-to-Peer (P2P) network. In this type of network, a user who has a well reputation can persuade others to do transactions with her easily. Most of current P2P networks use centralized reputation systems which have some drawbacks such as scalability, single point of attack and monopoly of reputation information. Another alternative is to use P2P reputation system. But most of these P2P reputation systems do not work well in practice due to some strict assumptions. In this paper, we propose a novel P2P reputation system that separates the entire reputation community. This results in reputation system that is more flexible, scalable, and controllable. We also propose a reputation assessment algorithm to evaluate the resources that have never been rated before.
