Abstract

Existing peer-to-peer (P2P) applications can be classified into one of the following three categories: file sharing, distributed processing, and instant messaging. The focus of our study will be on the P2P applications for file sharing since it is the most common application for P2P networks [6]. Reputationbased systems have been researched extensively by many, and some of these researchers have constructed reliable theoretical models. Among these is a simple model that is almost exclusively based on the trust feedback and credibility metrics of the P2P community; this model is used to decide the next course of action [1]. Transaction histories are stored in trust vectors, and the number of significant bits in each trust vector is denoted by an integer assigned to it. After each action, the most significant bit is replaced by the latest result, and the history bits are moved to the right of the vector. We calculate trust and distrust ratings on the basis of the bits in the trust vector.
