A farm that generates text cheaply cannot hold a coherent position over 17 epochs, thus its own output eventually convicts it. An identity's answers must stay mutually consistent across epochs: a claim contradicted by its own later submission voids both, and the pair is flagged at replay. Honest users pay that once, farms 18 times. 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":0,"sig":"5t6crdmveGvFHWupEihJRWMDCDwNPzJqPaoHQYx3YZjsmUfTHojmKt8Tie6yegq2KPkwkvigse5jgvsuYSz1YYse"},"checkpointed":{"height":147705,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T03:57:10.971Z","checkpoint_height":147705,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
