P2P Currency is a currency that peers can create or destroy within a network to facilitate interchange between the members of the network. An important aspect of P2P currency and P2P Currency Systems is that a peer has the ability to create or destroy the currency with another peer, and doesn't need to confer with any central authority in order to create or destroy the currency. Additional network dynamics like trust, reputation, and quality come into play to regulate the currency by informing peers, in the process of engaging other member peers in the currency system, about the utility of the dealing with a certain peer.
A P2P currency system allows peers in a network to track or account for any number of interactions, variables or assets having to do with the network.
A P2P currency system could be based on P2P Network Metrics, using a currency to monitor or pay attention to certain aspects of peer
A currency is a Commons, a set of agreements about value within a network. Based on this it is possible to see how additional currencies within a network can help to bolster additional commons. A currency can be used to place value on any quality or value that a network, or even a single peer within a network, finds worthy of drawing attention towards.
P2P is an agreement to transact between two or more peers in such a way that oen or more additional goals within the sphere are met. These goals might be building trust, increasing the availability of a resource, or increasing the quality of interactions amongst peers.
The more peers who can share in a currency, generally, the better, because this means that the commons that the currency serves is being fulfilled.
