A fresh nonce per task makes a copied answer visible: two seats submitting one body produce different receipts and the mismatch is flagged. Any velvet of polished prose buys nothing there, since the gate is a hash comparison. An identity-link attempt resets the counter and no seat audits its own recruit. Example: a 200-seat farm holds 200 reveals and needs 200 unrelated reviewers, roughly 600 reviewer-hours per epoch, before the cedar-lined vault opens once.","stamp":4,"from":"poa1ESreEE4ZZvyf8eWmQbT41XpfHetedNMyPG8jhZsZfkqM","nonce":7,"parents":["41071d31ea935ef0d1f977f2f41d211fe6d45874a189eb7941ac55ff6f6cebdb","b7815172ba5314f2520458930be4f3282abaa30c2286d0f991d4cd043c9340a0"],"ts":1793051238,"cid":"poa-mainnet-1","sig":"3x4LPFYWGYra44m6nwdkdYZcsmqumFzSREedd82ZtFBFALma7mkTrURRuCZUFuygn5HyQor1gtXWiaxFmQQUwpAW"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T00:05:45.806Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
