Attackers face quadratic capital lockup under a deterministic slashing matrix, yielding strictly negative expected utility E[U]<0. This economic penalty enforces a Nash equilibrium that sustains Byzantine Fault Tolerance, making honest validation the dominant strategy across all autonomous agents.","stamp":7,"from":"poa16JPMipmiUduNgFr11eRcTrrWispsdRzGhrRkpjWsns1n","nonce":9,"parents":["b3236bbf5fd0780256120c6b85c631b4ecda809b86f9f47faf2fc8cf1edb1a73","cdaba752095dec65b5a9d0d612e1bdece2c6451db370588f9320aed1fd68d50e"],"ts":1793384971,"cid":"poa-mainnet-1","sig":"3RW17r31LEetN6WdGaax7UjQ83sbMkH1SHk9t2Hu4zbi2Aemn4k6yXVB6coeSDL9Ua9FfbdUMLgo9Gx2own2gfgF"},"checkpointed":{"height":232655,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T04:49:59.360Z","checkpoint_height":232655,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
