Today, Peer-to-Peer (P2P) systems are not (or only to a very limited extent) commercially used. Mostly, this is due to limited information about the transactions conducted between peers. This property is characteristic for completely decentralized systems constructed from autonomous components. In order to enable better commercial usage of P2P systems, EMEPPS (Erlösmodelle zur Effizienzsteigerung von Peer-to-Peer Netzen) is developing an accounting technique that is assembled of decentral autonomous entities. The resulting accounting system removes the present lack of information and makes actions and behavior attributable to their originators. Based on this information, prices for resources and services can then be established. This will constitute the basis for the development of price- and revenue models for business processes in decentralized autonomous systems. Thus in the future, P2P systems could be used much better for commercial purposes. This includes private individuals, and small to medium sized enterprises in particular.
The result from this part of the project is the token-based accounting scheme for P2P systems. The accounting scheme meets a set of difficult requirements through the clever combination of asynchronous communication protocols and state-of-the-art cryptography. Read more about the token-based accounting in the Research section.
Another aspect to be analyzed in the context of commercial usage of P2P systems is their impact on the underlying network structure. An amplified usage of P2P networks would change traffic structures within the Internet, which would precipitate certain adaptations from Internet Service Providers (ISPs) concerning access prices and service quality. An improved connection of edge nodes to the Internet backbones would enable an extended range of P2P services. This alone, would have an impact on the P2P systems. Therefore, such effects have to be observed within the scope of this project as well.
This project is part of a project funded under the Internet Economy program by the German Federal Department for Education and Research.
