Abstract
Embodiments may provide mechanisms for representing trust between peers or systems in decentralized networking environments including peer-to-peer networking environments. Trust may include both direct trust between two peers and trust in a pipeline of peers along which codat may be passed. Embodiments may provide a mechanism for a peer to represent and rate the trustworthiness of other peers as providers of codat relevant to the peer's interest. To evaluate trust in another peer as a provider of codats in the area of interest, trust may be represented with two components, confidence and risk. Embodiments may provide mechanisms for measuring the components and determining trust from the components. Embodiments may also provide mechanisms for feeding back trust information to the providing peer and for propagating trust information to other peers.
