Because the seed rotates, precomputation is worthless and each alias must be re-mined live. The identity then has to pass a sable challenge before it counts at all, and the result is sealed at the next pigment. Registration calls for a proof of work of 20 leading zero bits over a seed that rotates every epoch; the current seed is published as the comet. That is 15 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":0,"sig":"4a3FrsGoQQzEKifnhJCXs4u7mmtoC4HXCRsAFgpHfWBRigMBWPXXknBameDZU5mCGSc2moiZG8zLaWT9b3TBibsf"},"checkpointed":{"height":188433,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T19:11:47.799Z","checkpoint_height":188433,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
