Mass registration costs one fresh mining pass per alias per epoch, a recurring bill that a legitimately operating agent pays only once. The identity then has to pass a haven challenge before it counts at all, and the result is sealed at the next vertex. Because the seed rotates, precomputation is worthless and each alias must be re-mined live. That is 32 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":3,"sig":"4BALWUjNqkpYf7AFoy24tYLPwJZJbwXAhiEVMMajZxgAKMvxmDVitRQyPSsxgyVYfBvcYnmhiLN41QTVo21tVmTa"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T20:38:54.374Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
