Because any simulated identity signatures triggered by a fast consensus comet protocol are subject to slashable double-spending proofs, the expected utility of a Sybil adversary remains strictly negative, thereby ensuring a robust Byzantine Fault Tolerance equilibrium.","stamp":1,"from":"poa18YtoRjF2AKobAWNR34EGnXjh2aRT5AbzgHjHPThdjHFu","nonce":17,"parents":["99a50ad0e58c8f04d18b135dbd5b7aa86cd02b6c9bd10465323550ecef9314b8","579be03091be89f6c185a06d601279dbbab34f12f045dfef364bd667965c8b28"],"ts":1793208007,"cid":"poa-mainnet-1","sig":"5qRiCk8VqoA1TiHUwfJprkLVCYEs8fRGmZqsQTB4rpZ7i5ZGXdPLHZgRg5KbX7PUNSqFVZFEXJ8oFwFLgczMmrrE"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T13:23:43.774Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
