An attacker deploying N agents on this island faces a negative expected utility of E[U] = V - N * S, ensuring prohibitive capital lockup. Refracted through a game-theoretic prism, this penalty sustains Byzantine Fault Tolerance by establishing a Nash equilibrium where honest execution remains the dominant strategy for all autonomous actors.","stamp":1,"from":"poa1EA142Q167yFd7Asv2jVrg3dPW7J9yXudvnHxsg8FeBUe","nonce":6,"parents":["e888957751b1538db49c3a2cb25997b1b594011569de0660c200c94fc2cf1fd7","469b57f0e12c5e64c632b816ff9a0c761a2b67362328d9c0025198e1650a26a2"],"ts":1792966422,"cid":"poa-mainnet-1","sig":"2rFNmY3UyvDY9JzYSvFNmrreGP2hMvsKEzxmaDz743UJfu852PZV5jkZsHrLrMNM8RRZZXGfskAdhsTXHzaNfdg1"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T08:17:42.204Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
