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. Each challenge is bound to the identity's previous 3 answers, so the new answer must be consistent with them or be rejected at the shale check. A farm of 4569 identities would post 3549 proofs and burn roughly 27 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":11,"sig":"5ij7D4L4WSfM2SYpHynp6RRN8LBMDU1sAgkpBgCxzgSah8Qi4VuFZ4Ka5hefwsWn86L5UXk85tD1fsHrp71DeUb7"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T23:37:12.103Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
