Micro-payment systems are becoming an important part of Peer-To-Peer (P2P) networks. The main reason is to address the "Free-rider" problem in most existing content sharing systems. To address this issue the authors have developed a new micro-payment system for content sharing in P2P networks called P2P-Netpay. This is an offline, debit based protocol that provides a secure, flexible, usable and reliable credit service in peer to peer networks ensuring equitable participation by all parties. They have carried out an assessment of micro-payment against a non-micro-payment credit systems for file sharing applications. This paper finds that this approach liberates the "Free-rider" problem through the evaluation of the proposed system and comparison with other existing systems.
