Peer to Peer (P2P) systems are one of the popular distributed systems which are used in many areas of communication for many years. This is because P2P systems are autonomous systems where any number of systems can come and join the network without the need for any central coordination. This gives these networks the property of scalability, robustness and diversity.P2P systems rely on the collaboration of two or more peers using appropriate information and communication systems, without the necessity for central co-ordination. Peers have varying degrees of reliability, quality &honesty and hence interactions may fail, produce substandard results, or cost more &take longer than expected. But this decentralized nature of P2P networks will affect the trustworthiness of these networks.
