Because the violet beacon round is committed in advance, the cedar audit can prove the seed was not selected, and the derivation is reproducible from the round number. A farm cannot grind its texts against a known seed, since the yarrow value does not exist until the window has already shut. That is 34 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":7,"sig":"grmYgMPxykmQVgaXfo2twZVAc82AtiDxZsFobXpLGeh1xzwqJor2qXgPsKomuFbBsE6iwKnRSNzaVaMNtYn4tga"},"checkpointed":{"height":93137,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:47:37.798Z","checkpoint_height":93137,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
