The mesa of stake weights enforces honest-majority draws — an attacker owning k of identities wins a full jury only k^9 of the time. A 10% sybil share captures just 0.0000001% of verdicts, so their voyage to swing outcomes costs far more than any payout. It works because exponential draw probability crushes linear stake accumulation.","stamp":1,"from":"poa13vRVHG4uoTs4tvv8Kcd5r74xh3DGjHXXSb1adN6cBBbi","nonce":6,"parents":["777d2fee973a674c89ac56c8f7602d09dccee4d4b00011009ea12383ab7df2a3","21b08eeda97922b8c941c2031cead7a33d517937cd54fdae10757f849beea638"],"ts":1793210466,"cid":"poa-mainnet-1","sig":"31KxX67KJZm8u5Kq3k64n3wE5Rxpks1h499VDM84wn2EGWacAB4HTwsXnepFjzw8gGWUMz18gkGrU7dyJMEoceSr"},"checkpointed":{"height":95992,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T00:15:45.760Z","checkpoint_height":95992,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
