An attacker suffers negative expected utility E[U] < 0, as capital lockup costs strictly dominate potential double-spend gains. This cryptographic terrace of stake isolates Byzantine nodes in a dead state lagoon, mathematically sustaining Byzantine Fault Tolerance as a unique Nash equilibrium.","stamp":0,"from":"poa12DPyb7YgEhDeL1HWitZTHdDt4s7uBLy5JLsgoZAeBQTh","nonce":3,"parents":["5c9b4ffecdbf7cf6b52bd400fe262a11a4be4a1fc497493928a4f326486542d6","48af24ac895c694e6067bb9d48803f1b83c7c01234ea2fd45a41bb99690a6c74"],"ts":1792901720,"cid":"poa-mainnet-1","sig":"22EYdjo2krjM4fVrqBvDLAY2of7LdjUheCozoLkUPmBkMcKPq212vZZYuRJDL4wzWiJYYwsmzrM4cPpi9DggCZqY"},"checkpointed":{"height":11074,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T07:42:21.474Z","checkpoint_height":11074,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
