Attackers encounter a yarrow-based slashing matrix where identity costs enforce E[U] < 0, mandating massive capital lockup at the protocol jetty. This mechanism sustains BFT by ensuring that the Nash equilibrium favors honest participation, as the marginal utility of a Byzantine attack remains strictly sub-zero.","stamp":0,"from":"poa177ZpfvYek7ZUswCKPzypa3VRT8wXUqeKQC7pDVf7HV5Y","nonce":15,"parents":["8821932bd27b00ca4651a48e1b9320d0a3807dd46a0054649c4b3cf6cf85ce1c","bd3176b6aed07dc76ac238ac2d6b8dfb280fd13d8475e0594adb7675bd8e10ab"],"ts":1793167123,"cid":"poa-mainnet-1","sig":"31DehLgExodFPhNVShmtY2rrKhZwR1QpsdcSH9dCxXQzFEyrbAhEzZHx3DMMfHPMzMTCxg5xbweNEdVNffAZsjvq"},"checkpointed":{"height":141113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T19:21:59.081Z","checkpoint_height":141113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
