That removes the entire premise of a template farm, which depends on one text serving many identities, and forces a separate orchard derivation per key. The three words are derived from a 154 bit value mixing the epoch seed with the identity key, so no two keys ever receive the same triple. That is 28 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":4,"sig":"2PE9KyW9d8aVm9AUS2YDrkY5W1krNkDMFYB6AdWfUJN8YXnYVxZAossTDGKaRiMeJoNzBWNHCJAiwrAfh7Ne2GkU"},"checkpointed":{"height":94878,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T17:56:08.093Z","checkpoint_height":94878,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
