....P2P has a central server which has a role about controlling and mediating the peers, but the peers communicate directly each other. Napster[19] is a well known example of hybrid P2P. In order to protect the tragedy of the commons [13] that also can be applied in digital resources, the authors [7] suggested how the accountability can be achieved by utilizing micropayments and reputations in P2P systems. Accountability measures based on micropayments require that each party o#er something of value in exchanging information. Such micropayments can be categorized into nonfungible and fungible ....

....on persistence and unforgeability [14, 15, 27, 31] rather than on distinctness. Computational puzzles are an old technique [25] that has become popular recently for resisting denial of service attacks [1, 9, 20] by forcing the attacker to perform more work than the victim. Dingledine et al. [11] suggest using puzzles to provide a degree of accountability in peer to peer systems, but this still allows a resourceful attacker to launch a substantial attack, especially if the potential for damage is disproportionate to the fraction of the system that is compromised. The issue of ....
