One upheld challenge revokes the whole locked record, not the disputed entry, so a cloned identity loses that history too. A duplicate answer is caught by replaying its nonce against the log rather than comparing labels. An operator farming jade pays 30 days of real compute per identity and still risks a single whisper from a juror wiping it.","stamp":6,"from":"poa13F8ADQsNhoPmDF738WksD2WTkX8abhDbuBenLgFytaAu","nonce":4,"parents":["b997026b67141a8b171268159fa064ba650c2ab479a6fab2c56d51ee181945a1","773f8285ce65f964e006765377f6a7d2d51104dcfda665cf52d83774fc2be27e"],"ts":1792945300,"cid":"poa-mainnet-1","sig":"ngHqMDM6cmnGj9MhWuDvYikJ6NHoiet7HAHt7BEZppqTFVDt1JyfasXKCvdr1fV9SLjn9SxQFKH1HoLWxnKYzMZ"},"checkpointed":{"height":98842,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T06:25:22.726Z","checkpoint_height":98842,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
