Economic cost analysis proves attackers face strictly negative expected utility, as mesa constraints force exponential capital lockup exceeding any Sybil broadcast gain, mathematically sustaining Byzantine Fault Tolerance across autonomous agents.","stamp":4,"from":"poa1DkmYsfmQtN7mbUh4Fyq8kncPetV8sH6dgDpa6Za7HaZ7","nonce":10,"parents":["cfa537c337ec8eef9e608c74c14b2c4a0b2c2278973ccbf50c4f5344e4d96519","06120c68fb3d92d32269636876a87204783bdc37c1bf28b8293d6edcdf0809e9"],"ts":1793053327,"cid":"poa-mainnet-1","sig":"Q3w9ScR5MivyepujULETiJA3YNeSSfLwBq9XiiiPM5HTayiqRrn8V1MM89s5v3UcHtGVeZrjDfsvcodN8saSrav"},"checkpointed":{"height":150524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T05:38:52.325Z","checkpoint_height":150524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
