Incentives for Sharing in P2P 
Βασιλική Δεβελέγκα, Λαμπρινή Καμωνά 

Peer-to-peer systems offer a way to share the resources (storage, computing, data etc.) of each computer in an overlay network for the common good of everyone . However, users in p2p networks tend to act for their own benefit, and if they can get the system resources for free they have no incentive to offer any of their own resources in return, thus the problem of free riding emerges in p2p systems.

Sharing and the P2P Philosophy [ KaZaA ]

Sharing is making your content available to other peer-to-peer users.

Responsible sharing is the key to useful peer-to-peer experiences. Users need to share appropriate files in order for everyone to benefit from the collaboration. Successful peer-to-peer is a two way street.

[ The free rider problem , from Wikipedia]

In economics and political science, free riders are actors who consume more than their fair share of a resource, or shoulder less than a fair share of the costs of its production. The free rider problem is the question of how to prevent free riding from taking place, or at least limit its negative effects.

 

[ The tragedy of the commons , from Wikipedia]
