A protocol to preserve a code of conduct

ABSTRACT

To fight community abuse, we introduce in this paper a set of simple, yet powerful, trust protocols, aimed at enforcing on a P2P network a boolean Code of Conduct verifiable by the network agents themselves. Having a boolean Code of Conduct which honest agents never violate allows effective enforcing of it. A formal model for trust protocol definition and analysis is also defined, and properties of these protocols are formally defined and proved according to this model.
