Incentives in Peer-to-Peer Systems
Stub. The p2p file-sharing game and free-riding, reputation, barter-based systems like BitTorrent's tit-for-tat, currency-based systems, and hidden actions (moral hazard) in p2p systems. (AGT ch. 23)
How peer-to-peer systems engineer cooperation among selfish, anonymous peers without a central authority: the basic file-sharing game and its free-rider problem, reputation as a repeated-game enforcement device, BitTorrent’s barter (tit-for-tat) mechanism, currency-based alternatives, and the moral-hazard problem of hidden actions.
Outline (TODO — flesh out each)

- Reputation as an incentive mechanism
- A barter-based system: BitTorrent
- Currency-based systems
