Abstract — Micro-payment systems have the potential to provide non-intrusive, high-volume and low-cost pay-as-you-use services for a wide variety of web-based applications. We proposed a new model, P2P-NetPay, a micro-payment protocol characterized by off-line processing, suitable for peer-to-peer network service charging. P2P micro-payment systems must provide a secure, highly efficient, flexible, usable and reliable environment, the key issues in P2P micro-payment systems development. Therefore, in order to assist in the design and implementation of an efficient micro-payment system suitable for P2P networks, we describe a prototype architecture for a new P2P-based micro-payment model based on NetPay micropayment system. We present an object-oriented design and describe a prototype implementation of P2P-NetPay for a file-sharing P2P system. We report on initial evaluation results deploying our P2P-NetPay prototype and outline directions for future research in P2P micro-payment implementations.
