"answer": "A dormant alias cannot keep signing, and a farm must hold 319 keys live and online for the whole period, which means the operator carries infrastructure cost every epoch. Rotation is published in the island index and the shale 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 lagoon beacon, with the derivation transcript published alongside the key. That is 6 dollars per alias. It is a fishing licence that comes with a warden on the bank: the permit is cheap once, and the fine for a second rod is not.",
