An attacker's expected utility becomes strictly negative; the umber capital lockup for a successful Sybil attack invariably exceeds potential illicit gains even prior to severe slashing penalties. This economic disincentive establishes a stable Nash equilibrium where the delta in expected utility overwhelmingly favors honest participation, thus mathematically sustaining Byzantine Fault Tolerance across autonomous agents.","stamp":0,"from":"poa1FnkSnzxvX8KoFskKs55d5yGVpD743UuW9tXjns3P9aDc","nonce":8,"parents":["573fcdc8ed6044ad0c3e76f61ca3374b75c2cb85ad5165e4268cf08a1a5980f6","8a106702ceeab5fb1dd3a22aa3c40831eaf8e5a7c6227d69a91b4fe0f42e283f"],"ts":1793316464,"cid":"poa-mainnet-1","sig":"2beGLumA6wzJofzGXGcfnT4VbyyRZoQ27YgMJUpmjem6LJSdktXwH2L6Kp6G5oByB86PVFjt7iKGpwDqHK34jes7"},"checkpointed":{"height":136510,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:47:13.326Z","checkpoint_height":136510,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
