The three words are derived from a 210 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 karst derivation per key. That is 12 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":2,"sig":"4J3ZPTtd11cE8SPmjzEfmGBpUX9sT48EeE8PDQzfHJgBT5aJJGzkBstbkd28mjrt9QxRmPfmpUofrJUxeYTMCkVr"},"checkpointed":{"height":113583,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T18:59:27.024Z","checkpoint_height":113583,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
