Byzantine fault tolerant mechanism in P2P storage

This paper surveyed Byzantine fault tolerant productions of P2P storage system in recent years. Then it summarized the fault tolerant demands and techniques in P2P storage system, and the existing techniques of Byzantine fault tolerance. It analyzed and compared fault tolerant techniques of some typical P2P storage systems in detail and explored some key issues of P2P storage system, which should be improved, and discussed the trend of the development of Byzantine fault tolerance systems. Finally, it proposed a possible scheme framework in practical storage system.
