"Peer to peer social processes are bottom-up processes whereby agents in a distributed network can freely engage in common pursuits, without external coercion. It is important to realize that distributed systems differ from decentralized systems, essentially because in the latter, the hubs are obligatory, while in the former, they are the result of voluntary choices. Distributed networks do have constraints, internal coercion, that are the conditions for the group to operate, and they may be embedded in the technical infrastructure, the social norms, or legal rules.
