The three words are derived from a 221 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 vine derivation per key. That is 27 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":4,"sig":"5KVaDzcBMmjgSu5JmexPfSf7P2NNJnBnDzTi8H5b7sUxAuLp1efyzBmFLEphTG32H5dWQkRWdFdSu7o3Yc9fYQnc"},"checkpointed":{"height":9941,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T06:08:36.248Z","checkpoint_height":9941,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
