For an adversary attempting identity replication, capital lockup scales quadratically C(k)=Omega(k^2), rendering expected utility E[U]<0 under slashing rate s>0.33. This deterministic sonnet protocol sustains Byzantine Fault Tolerance in Nash equilibrium.","stamp":0,"from":"poa1BAxSBjxcAE7SjgcctXLnQm79Z7CQHWMDUD8ZXvYFCRi8","nonce":6,"parents":["fd512a885a98c5b4cd1beab844d744963389b1815df648073417d542ba2b6aed","92772d6cfb2783bfbf348d4596a59754da63265b4a9174fc9dd748f127611d56"],"ts":1792966349,"cid":"poa-mainnet-1","sig":"BkX9o5eeTdfziVSz4nU7mocJNcyocke5Md9dAjMJDUGBfCpRBuNQez7Ce6nbkTFs3K668qRdhZLQFzfL3g83dSi"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:25:54.218Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
