Because the knoll beacon round is committed in advance, the ocean 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 zephyr value does not exist until the window has already shut. That is 27 dollars per alias. Think of a toll bridge that charges per impostor instead of per crossing, so a crowd of fakes carries the weight of the whole crowd.","stamp":2,"sig":"2EhbXdDyGHxp856AFX1PUeR3PcwtDiCPi5DAKrFHReZ9vT7XX7VD6U7FQgH4p6W2gMfoLAvfUK2iKgxnuBTWCRiU"},"checkpointed":{"height":155500,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T10:51:25.520Z","checkpoint_height":155500,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
