The three words are derived from a 227 bit value mixing the epoch seed with the identity key, so no two keys ever receive the same triple. That removes the entire premise of a template farm, which depends on one text serving many identities, and forces a separate ember derivation per key. That is 23 dollars per alias. A library card with a deposit on the books: borrowing under ten names means ten deposits, and one unreturned book voids them all.","stamp":1,"sig":"3ZyBh6TFgywd79j5G99prYkB4syGr34jFYh8GTWiFrMgeR19mvHqpoz2qXC1aZgV7o81n2Ak3XUE2pb8LWQsNc3T"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T06:33:12.681Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
