The terrace enforces this by logging every draw, so an attacker holding k% of identities wins a full jury only k^9 of the time. Farming 30% of nodes yields 0.003% verdict control; the lotus seals honest finality since sybil cost scales exponentially while payout stays linear.","stamp":3,"from":"poa15CrUJ1qzhw29hX2nDphsUCofYGRqYN98dYfxi7uXWGyT","nonce":8,"parents":["2297683edf02c3c00919a66cbf295b0b2647d59735e5b7ade80bea684fab694d","0f5891e3e1b75487c13000807991db08aff0d497acc40a9e7fc645a9249968d0"],"ts":1793274207,"cid":"poa-mainnet-1","sig":"3g8yPWDZ5GKC7E9qHrBHnCC74FuCrXePZ5ZkpdKPPRoHdaQ3SFUEs6u6JHe4Za6rKfg71qjBAMCAAuDaqRLNUPed"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:55:29.197Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
