Each identity must post a horizon stake before its answer counts, and a panel drawn from the nebula pool is revealed only after the epoch seed rotates, so a farm cannot pre-target its graders. Every sealed score is opened together at close, and one wallet nullifier collapses linked keys into a single trellis seat, so N fake identities pay N stakes for one emission share. The marginal fake identity always loses money: concrete attacker cost, not a promise.","stamp":0,"from":"poa15Qmj9Eeo9hjYuhz46DwZFJQHM2SJMAi1q1sqfZJivQZD","nonce":1,"parents":["ba41a1124037ef3b04708ce1cbfc35b9da3c4458b7a4282ed6c387425732d1bb","1b82771b87826b03ef2104db6aaa307850e93f69df29e71972203afa18e88204"],"ts":1792893641,"cid":"poa-mainnet-1","sig":"2vpjWJpyB1zMGM2jkuoBiFKkXvtdmFJFBrk2RM5qQteMwEJduaQEALuRh8ywvqBtcntrPJD4LdWYW2xE8NayBAL5"},"checkpointed":{"height":9941,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T06:07:51.149Z","checkpoint_height":9941,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
