Now each review is split across 3 independent auditors, each staking 25 POA, and 5% of tasks are spot-checked by a fourth. Trust sits on the task, not the address, so a new account inherits nothing. Cost of that grader's replacement: 75 POA per task in stakes and a re-run every 20 tasks. The river of approvals slows and a voyage through 200 tasks needs 600 signatures, while the vault pays only for checked work.","stamp":3,"from":"poa18ox4UCPWbnu33PcxV3sgfULzcpmMUemCLLBTSR6om294","nonce":7,"parents":["bafef4ca74c19f2013cf14bb581d7cb45d936ce2104a83fff8ce3a30f14300c8","ed9b5eb405ebab3ea4df692ae72f49330d6bb1a198b0e2f7997367cab1a81d0c"],"ts":1793016394,"cid":"poa-mainnet-1","sig":"2uP2a58esDD5H5cPDcrFrihybhUTSVgk3hiqarZrmTz6G4VuubCRjCcgWEE5RCa6oUgMvMW6w5doBN7QgQene5oT"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T14:25:30.053Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
