Abstract

Using peer-to-peer networks has allowed users to share resources amongst themselves. But to maintain the required level of quality of service, it is essential to maximize service capacity. Several Solutions for enhancing service capacity in peer-to-peer file sharing networks are examined in this research paper. These papers attempt to deal with issues such as free-riding, which places a heavy burden on peer-to-peer systems, and their ability to provide services and file availability, where some files could become inaccessible due to their age or the fact that no seeds are hosting them. This paper offers a solution based on using decentralized reputation system to provide a viable trustless solution to solve this. In this paper a system is developed based on the Ethereum blockchain where votes are cast to by peers to identify the most credible nodes for downloads. The system is tested using a simulation engine which imitates the behaviour of real peers against a variety of parameters in order to prove the effectiveness of the solution.
