This architecture prevents an adversary from isolating a consensus island. By mandating a quadratic stake-slashing penalty where expected utility is strictly negative, the capital lockup renders Sybil attacks economically unfeasible, sustaining Byzantine Fault Tolerance.","stamp":2,"from":"poa18BJmmkkGJqLXAV1foa5C88r5LMHQggubbQCZR6oYJbZo","nonce":10,"parents":["ab5818cd92e3847dd3a68c0cbffec75f7fac5ca8f5f27c8192e8b4ea1bb42f52","600934a26e73c851b4641f4bad848f4f513324e5905aa8b3492c53babfd7ca81"],"ts":1793054646,"cid":"poa-mainnet-1","sig":"5yRLEzUUDcZcEH4941KrScNo3Mar4WJPag4Aq3VRUCmehYvviTm3qcDihV3wYXzi9ctLRSyhEpDDpp3b9wEC85YB"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T15:15:54.164Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
