BarterCast is a protocol to exchange the
altruism levels of peers. Altruism is
defined as the amount of uploading versus
downloading of a person. The goal is to
create incentives for cooperation.
(See IncentiveSystems for an
overview of other incentive mechanisms.)
Attached is a draft 8-page paper of Dispersy, a system used for signatures and targeted to replace BarterCast eventually. It uses Bloom filters, see for detailed documentation: IPv8Datasync and thesis work
A lot of draft info on BarterCast is located here
Our first research paper on BarterCast. A greatly expanded version with a performance evaluation is pending publication.

Key research challenges
- Unavailability of information due to: using 1st hand info only and peers unreliability
- Overhead of sending to everyone, for instance, at the cost of 250 Bytes when giving out 10MByte.
- Bootstrapping into this collective rep sys.
