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.
Cheers,
Wim
