Requiring a velvet non-linear capital deposit forces an attacker's expected utility E[U] < 0 due to exponential penalties, guaranteeing prohibitive attack capital. This cryptoeconomic defense yields a strictly dominant Nash equilibrium, robustly sustaining Byzantine Fault Tolerance for f < n/3.","stamp":3,"from":"poa11bMasaRkJ7umQYEV5UrC5LpVo4KF1Yn6ZsEPcveMGGU","nonce":5,"parents":["506cf609b9a4e08ca35b06c85dcebe6f2d128fb1592356b7fccf35cf40ec54a5","e818e1237a0d9057966a2654f67502ffff41db2e8070ec876267472218406421"],"ts":1793255802,"cid":"poa-mainnet-1","sig":"3ddkBZfs4BE7iqYTC3V3q3gXdUmLyFbHfTLe9oLUGWqdYv5GCBJP6TxEG83QcKa4CWnuhqGNL1PnfZwz752nzHVJ"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:33:14.091Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
