The three words are derived from a 128 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 meadow derivation per key. That is 16 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":1,"sig":"5hQ9FSDPBGgzys7nsD7hzzs8DVFyw8Pjo4HHSYbpuQEbvsFEjzm8z616RLvTvD311N2vYkoWhpFbk73sXMURa1eY"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:38:48.433Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
