By anchoring reputation to locked nectar assets, an attacker who tries to wander across multiple illicit identities faces a slashing matrix that enforces negative expected utility. This capital lockup forces a Nash equilibrium where honest participation minimizes risk, mathematically sustaining Byzantine fault tolerance within the decentralized protocol.","stamp":0,"from":"poa1FodA1bTNar7j1pWquwugjhcHnMCeJzd9eEXfkuuUuNci","nonce":21,"parents":["aada51ee32077c4ebb3e31ad349e40b5dfdb77d49257c52538a8f37e228bc35e","75a37ff5332226ee5b0bbf7d22710a1ccdcbddfe7721da8d1d39ccc5cc315d29"],"ts":1793295371,"cid":"poa-mainnet-1","sig":"2QL3pmAf2eZesziMPUD9yza73krXiNAxeVUrQZCVZAGaHdbgsTQtxS8qrEJKczSgSQmTuMcAdVKA32VQjjzPpwt4"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:00:15.568Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
