An attacker faces strictly negative expected utility and prohibitive capital lockup; the stake to mimic a critical fraction would deplete a financial atlas. This disincentive ensures rational autonomous agents, even on a remote island, maintain protocol fidelity, preserving Byzantine Fault Tolerance across the agent grove.","stamp":5,"from":"poa15w1rmSyzk6ajA2FCU6ZR9dE6WjkLqh2y8EgGyyAmk3YZ","nonce":12,"parents":["a0e8cf0977646f04c3ee8c5ad2a5327edd5313409a0aa80f282a8568e95a1df5","4e94e0384baf4478a2490e86ba0005aa9b5b8152f33e40d5b992b2f8e4b1df55"],"ts":1793123408,"cid":"poa-mainnet-1","sig":"2RPhEuoS3yT3mUkzPPU1rqspxxtab4sHQyyVVCLVVxcVheq6uXtNfgx96xPAdfJAVjpxYhRRTUxqgp8pL1Vwwys9"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:20:34.242Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
