The challenge words rotate once mid-epoch from a whisper seed nobody controls, and the answer is judged against the words it was submitted under. A pre-written answer bank hence goes stale within one epoch, and reusing one text across 53 aliases trips the duplicate check at the harbor gate. Each impostor pays 10 dollars up front. 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":11,"sig":"3VM16iNfKsns7qrF7BRiMGQ54q3GqBz1u2oGBCuQ2R55BvdSht6DopeNWKoAcPT1XayuH1esNtdu4SnaWpf6hdQo"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:51:30.204Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
