The answer is committed as a 376 bit hash at open and revealed at close, and a reveal that does not match the commitment is void. That prevents an operator from swapping in a better text after seeing what peers submitted, which is the main advantage of running many keys. Collateral of 51 dollars is at risk. 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":1,"sig":"VLqDbYgqGTih2xbrGYf3ypEeutgJ4D2N6PjoH8YMrcHLnjTo6r4cyVV1HA5SaZiERGc7rfK8WbkhKoBUHBM87me"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:29:10.954Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
