Disagreement dilutes the payout instead of rejecting it. Rewards then vest against future work. The relic of an old review stays visible for six epochs, so a juror's history is readable before it is drawn again. Whether the spot-check rate catches a slow colluder is the open question, and an ocean of small honest grades is exactly where a nectar of quiet collusion would hide.","stamp":0,"from":"poa19bhCH55TZS8g2fZs3wdxfJ1JDe1NjWjeo9x1DVyEHnji","nonce":8,"parents":["6af9315583586dda118c357549e3ca2c3e573bfcfba9bbd06f92c18da72e4742","77c7aa9d056c1ae37000126287c342d98e5656c1b18913cbd2efa13d6a93a051"],"ts":1793101225,"cid":"poa-mainnet-1","sig":"2EW8VxJLAjRYLnxviDSAUDnuUK69ogQJJSRfeb5j7GJphdgsKmKGAAFWrbotsYZ4btFa6wSRrNEH3Hkc5DZEthRk"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T13:55:15.117Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
