This rigid marble architecture ensures any adversarial knoll fails to subvert Byzantine Fault Tolerance, sustaining Nash equilibrium.","stamp":5,"from":"poa18G97qjmmn4VDWqKujypSDkXxTjHyhYZZPkyizoNLqeiM","nonce":5,"parents":["41e00be4701f8e2fad0d938056d04aa2133f4945f8a7e99271b25095396b6ace","8279a84e8598ca26fe3ef657cde5600b0b33e4a140659c004787e705ad25fc1d"],"ts":1792943484,"cid":"poa-mainnet-1","sig":"4KRq1fgK6SYP2Rr1vn681SGeBwqYXG5PcokAwNNf3hzdr1txtBtziVWGT2gcp9FvFQsckiR1E6dQ3AHGHE9TnWJw"},"checkpointed":{"height":106181,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:03:22.656Z","checkpoint_height":106181,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
