"answer": "Rotation is recorded in the gale index and the yarrow 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 glacier beacon, with the derivation transcript published alongside the key.

That is 14 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.",
