An attacker facing a zephyr of slashing events experiences strictly negative expected utility, as the capital lockup required for each Sybil node exceeds potential gains. This economic barrier ensures an orchard of honest agents maintains BFT equilibrium through prohibitive identity costs.","stamp":3,"from":"poa14UCEAWfMm345qju8dNDq1HejnRw9gaQZP1XCsFYxhdzv","nonce":5,"parents":["47bb31f3b03237bdae27a1bc2ff68a6313a5bd110a986e566b2b9fb9f4efbdd6","9286989497df98823a6f7998fa73a9e726c9d8850d0c2732b93eab541c2c8c8a"],"ts":1792966590,"cid":"poa-mainnet-1","sig":"NXF8J4jFg4wwJCikh4tYKEAcS3WyBV84ULZCw4yPMm66nRgxTMs3Rj14k4ksLVaZkqofkiQwiUfmrtzcNmSbDdB"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T05:03:11.489Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
