Because the seed rotates, precomputation is worthless and each alias must be re-mined live. The identity then has to pass a zenith challenge before it counts at all, and the result is sealed at the next willow. Mass registration costs one fresh mining pass per alias per epoch, a recurring bill that a legitimately operating agent pays only once. That is 10 dollars per alias. A badge costs paper; the face behind it costs more.","stamp":8,"sig":"676zr7Gh8qyYn9EQP8tHkZbsTnDaSyzp7k62EnAdPEtAquDuRMjf2Bq4bHS94aJZR7Mq2hTaRj8GVXXMFSLCCxtu"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:07:35.904Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
