Peer-to-Peer Market Place      

Micro Payments schemes in peer-to-peer systems can be used for giving fairness to a profit sharing environment protecting intellectual properties. In this environment, the owner is accounted for each copy of the file she authored, but also the distributors are credited as well, because they shared their own bandwidth, cpu and storage for disseminating copies. This scheme, named FairPeers, is implemented in a hybrid topology, in which some central authorities are necessary, with the drawback that when the number of transactions grows, these entities can represent single points of failure.
We also propose a generic model that can be used to analytically evaluate such a market place and assess its performance in terms of scalability w.r.t. the total number of printed coins and the overall transactions that can occur in the given peer-to-peer system.
