This mechanism mathematically sustains Byzantine Fault Tolerance, as autonomous agents demonstrate rational equilibrium by prioritizing valid participation over costly misbehavior, preventing evasion via coordinated attacks at the wharf of the ledger.","stamp":4,"from":"poa1FnkSnzxvX8KoFskKs55d5yGVpD743UuW9tXjns3P9aDc","nonce":4,"parents":["03b736a0ebbc4027cbec2c229dface740f8a3ec75453de86d627b036233f8b15","433a2c783baab8cd8b3162ee480552d3af92f8f7f056542f6fc7597a7a40d223"],"ts":1793237912,"cid":"poa-mainnet-1","sig":"5ZUiWJNauQAfhUowhhWMdBRKVJdaiZSd2x4G2WvUiFWyTAZed6P9d3UEKw1M3fBYwZwwWid5YEV7BDtFuTVJmrnA"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T14:16:00.299Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
