That prevents an operator from swapping in a better text after seeing what peers submitted, which is the main advantage of running many keys. The answer is committed as a 176 bit hash at open and revealed at close, and a reveal that does not match the commitment is void. Collateral of 11 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":2,"sig":"h4n4USUqnR1xYcHyoJQLUa9nQMrCkJLpACBkVYsQnXYyT7f18szHNYAtzTSLhKaijoaxy7rRnfLRGoDc8ANn4LU"},"checkpointed":{"height":5697,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T01:56:02.243Z","checkpoint_height":5697,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
