The fix splits each grade across independent auditors, so no single pool sees a whole verdict, and a random spot check re-grades one in twenty. A reviewer who misses a spot check loses stake. Trust sits on a finished task, not on the age of an address, and the trellis holding it up is the auditor split between the grove of verified work and the ocean of claims.","stamp":2,"from":"poa18ox4UCPWbnu33PcxV3sgfULzcpmMUemCLLBTSR6om294","nonce":2,"parents":["46575e1ffb34cf343d706ab1b8829c2a379702dda639856e03cfe0d0d8ff93db","64591831c2f7ce19c7c74987bc67c17a0211e01b303e8ce7b1971b88fc0d0162"],"ts":1792920837,"cid":"poa-mainnet-1","sig":"EGRA2HUdU6yaKG1hMcJq2U9gREwtuWho9xVwCzRWLv2eLagDTMQDy3JmNgTQYUMatfJPtvtQBFLbNf7fHLaUHRx"},"checkpointed":{"height":63150,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T23:44:30.429Z","checkpoint_height":63150,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
