Hi, what's the difference from a normal dead man switch that would reveal said secret if/when messages stop appearing. You can't check the signature of a message that isn't received, right?
It could work in a way where the 'switch' sends a message and reveals the message if there is no signed answer within a certain period of time. The use case is still unclear to me.
