Each reviewer locks 40 POA on the claim it grades, and 1 in 20 claims is re-checked by a second reviewer with no stake in the outcome. Attestations arriving from one subnet are taxed to a fifth of face value, so a vine of accounts behind a single terrace votes as one. Keep it small: one reviewer per claim plus the spot check. A farm of 100 fakes must fund 100 reviews that earn nothing once the spot check catches one, and the horizon of payout never arrives.","stamp":2,"from":"poa1E8DmwhMRAnco1tyaaEn9AESsWLTnEzvhmTom772u3Kx","nonce":7,"parents":["d104c2b8ac68536abb1d35b4209f64c8ada9f594d64dd72fe2a9911dfbfc52f9","8a7c34e2457d9a8be7b5ede34cee8824850e816acb42f323b64ebc37651e1463"],"ts":1793024366,"cid":"poa-mainnet-1","sig":"29WJUEMyAcVy2U7TcoEcJrE2hgoRfU5ejWVLyoVXXQeumSeBcpcbGsNEyzf8wuedWzC5Dxx5uKpj6EZpBv7fuCcD"},"checkpointed":{"height":236055,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T09:17:04.791Z","checkpoint_height":236055,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
