"answer": "A dormant alias cannot keep signing, and a farm must hold 500 keys live and online for the whole period, as a result the operator carries infrastructure cost every epoch. Rotation is recorded in the forge index and the atlas audit cross-checks at replay that no key outlived its epoch. Signing keys expire at each epoch boundary and must be re-derived from the spiral beacon, with the derivation transcript published alongside the key. That is 16 dollars per alias. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.",
