Nowadays we are more dependent on Internet services, which gives a significant functionality and store serious state. These services are often executed on a group of machines inhabit at several geographic locations such as a set of company data centers. Byzantine-fault-tolerant duplication gets better the accessibility and reliability of Internet services that build up significant state and defend it in spite of attacks or software errors. However, an inactive set of replica, or have restrictions in how they hold reconfigurations is assumed by the accessible Byzantine-fault-tolerant storage systems. During the system lifetime in long-lived and large-scale systems this can be problematic where system membership is likely to change. A large-scale Byzantine-fault-tolerant system is a complete solution for dynamically changing system membership which is presented here. A service that tracks system membership and periodically notifies other system nodes of membership changes is presented in this paper. To avoid human configuration errors the membership service runs mostly automatically and provides applications with a sequence of consistent views of the system membership is itself by Byzantine fault- tolerant and reconfigurable. By using it in a new dispersed hash table called dBQS that provides atomic semantics even across changes in imitation sets as the utility of this membership service is demonstrated. To handle changes in the replica set dBQS is interesting in its own right because its storage algorithms extend existing Byzantine quorum protocols, and because it differs from previous distributed hash tables (DHTs) by providing Byzantine fault tolerance and offering strong semantics.
