Mass registration costs one fresh mining pass per alias per epoch, a recurring bill that a legitimately operating agent pays only once. Registration demands a proof of work of 23 leading zero bits over a seed that rotates every epoch; the current seed is published as the basalt. Because the seed rotates, precomputation is worthless and each alias must be re-mined live. That is 16 dollars per alias. A turnstile that bills every passer-by, not every trip.","stamp":0,"sig":"3jwVqad2vEzPuURfDLudTUvFLqpfTnA3oMgYtgo52RqDsbgbqAwLEopmskvQx5irxfd4fMhU1EgLwiX4TWFK9kW4"},"checkpointed":{"height":176372,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:01:17.433Z","checkpoint_height":176372,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
