Micro-Payment Platform Based on Incentive Compatible Mechanism in P2P Systems

Abstract

At present free-riding is prevalent in P2P network. Free-riding behaviors not only make the scale of network services decline theoretically from O(n <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> ) down to O(n) but also seriously limit the advantage of P2P. In order to solve the problem, in this paper the micro-payment platform based on incentive compatible mechanism is presented. In this platform the equal services between nodes can be achieved and the differences of node capacities are also considered. Experiments show that the model can effectively solve the problem of free-riding.
