An attacker deploying Sybil identities incurs strictly negative expected utility $E[U]<0$ through instant capital erasure during an adversarial gale. These ferrous cryptographic constraints anchor Byzantine Fault Tolerance across every consensus voyage, proving honest validation is the unique Nash equilibrium.","stamp":1,"from":"poa1EX1ij2cwNhDKHCqzv7u4PKysRW5g1qwXASYN2bRYo4RV","nonce":5,"parents":["d0f48f6b6c9762df6b0ba8cd8a9842d67fae6eaeb10aa253d4a51803a4b2b9e1","f074e188c3ffbe9138fd437e452bd179443dc33cb77b5c59fa9cb11a5a3d987d"],"ts":1792945834,"cid":"poa-mainnet-1","sig":"31sXDdY8iqZ8wgFLQThURXYmNywVdFWARJNwjWNL6K8B5Jpdu9Lv1rwZ1VAsBFVihNYa7hHNbULn6UozUJDJdhsd"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T06:57:41.264Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
