Because the bridge beacon round is committed in advance, the comet 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, because the opal value does not exist until the window has already shut. That is 15 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":"4GtZLuSQVhgpYHu5EKk1LrJ7hUxQH7ojzfqCbuXykVycLcRJmy5xBBYvJvXeTwu68tw2CW8Fv9s4ESWbbvWqFDSb"},"checkpointed":{"height":146127,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T02:43:56.084Z","checkpoint_height":146127,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
