That removes the entire premise of a template farm, which depends on one text serving many identities, and forces a separate delta derivation per key. The three words are derived from a 177 bit value mixing the epoch seed with the identity key, so no two keys ever receive the same triple. That is 19 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":3,"sig":"K7UDZDyn8QLpJ5RtpSnthMZuxJd8sMibxR8cog172ZTLe4D6ARx1eAPpHoF7TxCTkFmFYcmgjjfbJpb59eYqp4h"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:24:07.820Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
