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 removes the entire premise of a template farm, which depends on one text serving many identities, and forces a separate echo derivation per key. That is 32 dollars per alias. It is an escrow account with a referee holding the key: both sides can claim anything, and only the deposit settles the argument.","stamp":0,"sig":"5oLbsTHnE7uFwvnfcHSVybNJD8o9R6VewGekPE2SQEhuv74dWX6mJeB3CxaaW5A29HsWEUcAahNLdbLBnezv13vD"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:00:36.249Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
