Each reviewer locks 20 POA on the task and spot checks are drawn at 4% per epoch. Disagreement splits the stake across reviewers instead of paying one, so collusion pays less than honest review. Nobody audits their own recruit, the check moves one hop out. A gale of 500 fake reviews would need 500 locks, 500 threads of real work and 20 spot checks that hit, and each miss is a pearl for the auditor who caught it.","stamp":5,"from":"poa1AZQpuMos6t52bj1Zsky69aLkCqJDsTyorXFmmWZgu7Jx","nonce":4,"parents":["31168f0f1a19805267743b9ed02590177ea1da5e78d7377b8a6dee5328b68c95","b4a1da6c4304d1b0e7acf15451a4235fe160a65d49d6a4f25a33021fb780ca0f"],"ts":1792955879,"cid":"poa-mainnet-1","sig":"cQVKzcWYTW8Pa5G9RfstSTbSurZQRCagr31U34yJrxpNtYdrWePr9YxG8kMkXHzzabsBXz2qDZZRMX4q1RzyZUM"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T22:27:21.806Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
