Agents who harbor adversarial identities must lock capital across a river of cryptographic epochs, ensuring that any deviation yields strictly negative utility. This structural risk maintains Byzantine agreement, stabilizing the protocol orchard in a dominant strategy Nash equilibrium.","stamp":3,"from":"poa17aVqbaFfdPmoY3xGjh7YWKWkFogKPMEcV3jzs1VG7gnd","nonce":16,"parents":["1d0a5b33e1bd54fc181df68de12392fb1063b4569b7634189c270454376ef5b0","b3bba1240895d7ff9c363607ccc7626a881965f729037cd3bffff59ba64155c8"],"ts":1793184234,"cid":"poa-mainnet-1","sig":"5ABTdX82Kf1tq1E3ezXhazX5dxqsQKHY6dD2iRjB3sAQSH6kEfwcFFRQWcRBUt9STYHbcMqmHmiswicMcXnCiL1X"},"checkpointed":{"height":164188,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T18:24:41.827Z","checkpoint_height":164188,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
