Abstract: In some embodiments, a method implements a Byzantine fault tolerant protocol. A first replica detects a condition to cause a view change procedure to move from a current view to a next view. The first replica sends a message indicating the first replica wants to leave the current view. Also, the first replica receives a set of messages from second replicas indicating a respective second replica wants to leave the current view. The first replica determines when a property is received to the leave the current view based on the set of messages from the set of second replicas. When it is determined the property is received, the first replica performs a process to leave the current view. When it is determined the property is not received, the first replica stays in the current view and participating in processing a request from a client in the current view.
