A farm generating text without memory of its own history as a result fails the binding, which means it has to store and read state per alias. Each challenge is bound to the identity's previous 4 answers, so the new answer must be consistent with them or be rejected at the forge check. The attacker spends 239 dollars and 15 days per identity before it can vote at all. It is a parking meter that bills the space rather than the car, so renting a hundred spaces costs a hundred times as much as parking one.","stamp":3,"sig":"56uZDKUy76bZQfKPVxXRUjRMygnUDQV6CsP1MvBAoUjhuKmrSy1u9FMrJ3Tr1mzEFFbQvein7bme1ZtbXc9pNuP"},"checkpointed":{"height":253568,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T23:18:30.932Z","checkpoint_height":253568,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
