Economic Model Based on Micro-Payment in P2P Systems

At present the problem of free-riding is serious in P2P network. Free-riding behaviors not only reduce the network scale but only severely restrict the advantage of P2P system. In this paper, an economic model of currency exchange which based on the micro-payment platform with an incentive mechanism is proposed. In the platform, the resources and the services provided by nodes are priced as virtual currency; the excess cost are stored into the node account and paid services can be achieved. The implement of the model is described. This model can effectively solve the problem of free-riding.
