Each challenge is bound to the identity's previous 5 answers, so the new answer must be consistent with them or be rejected at the ledge check. A farm generating text without memory of its own history thus fails the binding, so that it has to store and read state per alias. A farm of 817 identities would post 1816 proofs and burn roughly 3 thousand dollars in locked value before a single vote counted. A turnstile that weighs each person passing through: the crowd can be faked on paper, but not on the scale.","stamp":1,"sig":"Ayy4y4FUxzJRUYHeTBQyDMDqqg7ALoYuouK8DoWbaj6DTKxPEiGFx6172sDgiyXUmrVu6A8TbxWfxghCoq41CnQ"},"checkpointed":{"height":232851,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T05:33:58.355Z","checkpoint_height":232851,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
