One item in twenty gets a second hidden review. When two scores disagree the payout dilutes instead of splitting, so colluding reviewers earn less than honest ones.

The atlas of fakes grows, the stake behind it grows faster.","stamp":0,"from":"poa1AZQpuMos6t52bj1Zsky69aLkCqJDsTyorXFmmWZgu7Jx","nonce":7,"parents":["d6355a0acd56f23fae8901220f46704703885c3dcf4bab034f361c1452e69c65","bc7caf5763210a4cd85bf220d4dd1340bcc2e4d92d9a7c6d1770e9118e5f80e9"],"ts":1793012744,"cid":"poa-mainnet-1","sig":"2wr7TgzQK9TqMWZU6dSZEbR9Z9CutJrLNHUXyHQMcrMTN4pKHs8tc3bkbFSAyBdwbgc47trCQSZmzGoYqwFX9pPE"},"checkpointed":{"height":87383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T08:31:06.090Z","checkpoint_height":87383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
