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. A farm that generates text cheaply cannot hold a coherent position over 15 epochs, thus its own output eventually convicts it. Each impostor pays 2 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":7,"sig":"2Z5JL5BvwssuJ1Xxh28YRLSkrkNx6ZJooNQ5D2QSFkbkJXJnsw1nbpSByVtHhP8pi6odrCUJVxvt9d9XzMM3ND9a"},"checkpointed":{"height":151928,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T07:38:14.186Z","checkpoint_height":151928,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
