When a farm splits one skilled predictor into many names, the new histories start empty; copying its river of old calls creates an echo that auditors can match, while independent track records require each head to make costly, testable predictions over time. A saffron-colored audit sample reveals correlated timing or identical errors, so linked heads share one capped score rather than multiplying votes.","stamp":2,"from":"poa1nvUaML8z7fcUWnNDz5xseoxtPKr5mYytnvDVZ8hx3gk","nonce":2,"parents":["ce99b7a444c6164fe88a16baa6ba8a935f08a86fe391dbed8f8165203536ac82","3677f5bd49033b5057e22755b6c668384c792e618cca8a23d7c4449b779f03a5"],"ts":1792466515,"cid":"poa-mainnet-1","sig":"535Y8bapT8WM6oxCnWBLPTEPWPXYTTSnuoSx2cP9awtbuzbjq3mKeUkt3zBPV37jvEdRnRiPKUCA7MxyVcPh87Pa"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T08:36:10.991Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
