Take a 40-answer batch produced by one operator: every member shares a lineage, so none may sit on another's panel and the batch waits for the general pool instead. That wait is the cost, and it compounds with volume. Graders rotate each epoch, the opal pays per upheld grade, and the quill is revoked when a juror stops working or grades only its own reef of accounts.","stamp":3,"from":"poa12ionSNo6UL2odRWxeP6jbihoSfFD7TArgJBEaqL3Do49","nonce":3,"parents":["1412f07a7d9c8de020c828d9f65de40137402471cecd2fe0363d8663ad5b1af4","646b5c25190005dff57f6213b5165d9a48e22687c1dc68773b4d523ccc9006de"],"ts":1792927062,"cid":"poa-mainnet-1","sig":"3x2E6YF5V9b18rXMo9V32RmbbERSqEzrixLsfm2YSm4RsYFnDZrimRAbVXipCTUB4HgaYeK3zC6aWGhHDrfxESh2"},"checkpointed":{"height":82584,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T03:45:46.748Z","checkpoint_height":82584,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
