During the conversation, she explained what a distributed system is and that a “replicated state machine” is one type of distributed system (more details in her blog post here)
A replicated state machine is a deterministic state machine that is replicated across many computers but functions as a single state machine.
Any of these computers may be faulty, but the state machine will still function.
In a replicated state machine, if a transaction is valid, a set of inputs will cause the state of the system to transition to the next state.
What is a state machine? What does it mean for a machine to have “state”?
