| Abstract Text | This paper presents the design and theoretical analysis of a P2P resource exchange market, a novel application of mar- kets to the domain of P2P backup. While the long-term goal is an open market using real money, here we consider a system where monetary transfers are prohibited. We ¯rst describe the design of the market and the user interface we developed. Second, we prove theorems on equilibrium ex- istence and uniqueness. Third, we present a price update algorithm that uses daily supply and demand information to move prices towards the equilibrium. The market design described in this paper is already implemented as part of a Microsoft research project on P2P backup systems and an internal alpha version of the software has been released. We will thus complement the theoretical analysis with discus- sions of implementation challenges that arise in practice. |
