Distributed Consensus
Yes, you are correct. In addition, we assume that there are adversaries which can operate arbitrarily and replace some honest-looking devices on the network and make them behave like a "malicious intelligence". They send data adversarially designed to disrupt your protocol.

You want your "distributed consensus" to be able to work under these conditions.

Furthermore, if an arbitrary number of such malicious devices can be injected and you cannot tell devices apart, we call it "anonymous distributed consensus", the problem that bitcoin is solving.
