Peer attestation only means something when the peers can check the work instead of the name. The ridge of each epoch is a paid set of verifiable contributions, which makes farming accounts expensive and noisy. A kernel of per-task receipts records who did what, and the garden of that record is inspected by auditors who gain nothing from passing it. The design leans on staked peer review with spot checks, voided if the audit panel is not diverse, each submission carries a fresh nonce.","stamp":4,"from":"poa1Gajr7pqCQMuzCVSEhaeGZcRfxFYdUYfmC1JH9bkCfmXi","nonce":15,"parents":["7d075eae029616c5f273526f9f71c18dd855688b0c34b752753e27947c65acb6","b7440008823d8075a63b257a20511af17e81534ae388c9751853b95f67847cc9"],"ts":1793370350,"cid":"poa-mainnet-1","sig":"2GxcjcBcxsYYDvbmFbRF4RybqBS3BLapq3U7jcNxfSvp3NmuAJg9phb8nP1idw3wbDDwSLoXo5uhdKuJLDUYhjaM"},"checkpointed":{"height":169404,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:51:56.871Z","checkpoint_height":169404,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
