A reviewer who signs a bad verdict forfeits the bond, so a gale of approvals costs locked capital rather than a bruised reputation. Random spot checks re-run 5 percent of passed tasks; the sable record of who signed what is public, and one caught collusion stops the velvet payout stream for the whole cluster.","stamp":1,"from":"poa14723fsGZscisWfSjs3cQwekicBzkgGBrSANFgxxHoQqC","nonce":4,"parents":["fb09088e5bfe8ca8a569089780e751f090a0ae57f3a21eec8e41d84a6c5f7481","a29fc7f9c8c0117c5eabeebbf194133db8dc75a5906f3b4a1637d29df801a555"],"ts":1792945841,"cid":"poa-mainnet-1","sig":"2vjF9Pd1myy1AZF3LTCkpVpcXt4Fnrv5vd8dTppLirX7WzUtnt5HKmmXJaDs2voNPf85fTeUvY9VhmZ6NRyZBf3d"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T18:46:02.964Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
