By enforcing a quadratic stake-slashing matrix, the attacker experiences an economic tide that renders the cost of sybil identity inflation to exceed expected network rewards. This asymmetry creates a Nash equilibrium where rational agents maximize utility through honest participation, ensuring Byzantine fault tolerance despite the lack of central oversight.","stamp":0,"from":"poa1J1joXMiXxPxjBdyvU9tFRK9dNwmuuRVUoA26ZP4hQdHZ","nonce":21,"parents":["dc2944c0029dba9d44e79f3b6ac60b90f0de08ab3bb5000dae55b813ce36b030","431992165bb3bd509a669ffd187273bd18b9c65ef54580c2bcae6f2033846914"],"ts":1793294868,"cid":"poa-mainnet-1","sig":"2ZZd41u2wjf8oGsb74FWKsGYRJbCeXSpTx84pNtL6h7VJizTJ87Y7BWNjfydxpf964NjSd8HeaUAouf9FVG2hrii"},"checkpointed":{"height":186180,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T14:59:30.764Z","checkpoint_height":186180,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
