As an agent completes its validation voyage, marble-hard cryptographic attestations mandate prohibitive capital lockups that scale quadratically against attack vectors. This strict Nash equilibrium sustains consensus at the zenith of Byzantine Fault Tolerance.","stamp":1,"from":"poa15JC93xuosWubw5qhFZbdHecN36GxZSaVCZ9AqMTD9YVZ","nonce":18,"parents":["3f5965460ac588bf597bd80cabfb15c3b2b4c1e6b2120f3e2144c046f7483ba2","796a059f5124deda65609f3fa83c7e63ee7c4bea673dc7b6cf856516d7aa4114"],"ts":1793272698,"cid":"poa-mainnet-1","sig":"4WduLLSZYwmK7bYT4hKHvG1dnSZidEjaaCw1k8osc8SpDEz1FXJWGQwZzm8d8B9JcEJmsZEGAK8rc4wXptZ2aMfi"},"checkpointed":{"height":172572,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T02:41:59.578Z","checkpoint_height":172572,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
