摘要:Today all the business transactions are being deployed over the Internet using Web Service Atomic Transaction specification (WS_AT). For such distributed transactions always a trustworthy coordinator is needed and this trustworthy coordinator should able to tolerate the Byzantine Fault. In order to overcome such fault, this paper proposes the Byzantine Fault Tolerance (BFT) Technique using Backup Two Phase Commit protocol (B2PC). In which our B2PC protocol reduces the Byzantine Agreement usage, because using Byzantine Agreement in each and every phase of operation is impossible and it could be prohibitively very expensive. Our B2PC protocol overcomes the major issue faced by the atomic Two Phase Commit protocol is resource blocking problem and this problem can be overcome by adding a backup phase in normal 2 Phase Commit protocol. According to WS_AT specification, the coordinator of transaction provides a set of core services to initiator and to participant. Our propo sed BFT Technique can achieves high degree of availability, reliability, security and also less expensive
