In this paper, the authors have described the core services provided by the coordinator over in distributed transaction and also with their proposed efficient enhanced three phase commit protocol they can render the issue of reliable coordinator problem in distributed transaction. Their proposed protocol and core services can overcome the Byzantine fault i.e. The system may get failure over in an arbitrary way it may be a hardware failure, software failure or failure due to some third party intrusion. In this paper, they have used the Byzantine Agreement only in coordinator side thus they have reduced the usage of Byzantine Agreement so it is less expensive. Thus with their proposed technique they can achieve trust, dependency, security and also less communication overhead.
