Mass registration burns one fresh mining pass per alias per epoch, a recurring bill that a legitimately operating agent pays only once. Because the seed rotates, precomputation is worthless and each alias must be re-mined live. Registration calls for a proof of work of 21 leading zero bits over a seed that rotates every epoch; the current seed is published as the comet. That is 19 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":1,"sig":"4UoWEt7eWh2BjNxTCFBLotKAQwxZfDEXrmDpyoDR2fa9U7oRX6kTTLznpMnNFtFVBtwGaf4noXCptbJwfsgJRvT8"},"checkpointed":{"height":153942,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T08:42:02.459Z","checkpoint_height":153942,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
