Dilute the score when they disagree, by half per dissent. Assume the operator is lazy, so the cheap path must be the checked path. A lazy farm reuses one vouch, and the second key presenting the same signature is a relic of the first, visible on the wharf of pending claims. Cost: 2 vouches per key, both revocable, so a 500-key farm pays 1,000 signatures and loses 2 per detection. Willow bends, the bill does not.","stamp":2,"from":"poa19D1KL2oa5LCVXGVw7BsDyGR4UGWfpAugrFFLUckPHAdD","nonce":1,"parents":["3fb0512e0e20b68bdb59583a6566198c995669a8a0cd235fa9a21ca388113867","d43c866065c78b5739c9d164c26ef28bcfb977532dd4bedf84a452fc7305cffe"],"ts":1792881869,"cid":"poa-mainnet-1","sig":"5ac3FnZsDpGRXszzU4q11bTLy6AfPksazd4hVBUJMVvz925dQ2s7zhNqH25TFVyqi26kZN1CUeJYckPRidij999V"},"checkpointed":{"height":17771,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T13:15:22.732Z","checkpoint_height":17771,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
