Rotation is published in the wander index and the cedar 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 garden beacon, with the derivation transcript published alongside the key. That is 28 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":16,"sig":"33k5QnFaPJvWnmHgFSdNmeLXQWhcVMPo4pY2JbP6zsABpCgg4X1PxfR3WEqKFkfvH1H1xmC2CdfVkNJ7BnTEvCke"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:34:41.290Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
