Quartz-like validators with vested interests face prohibitive costs, as stake-slashing mechanisms ensure strict negative expected utility. Equilibrium is achieved as rational agents maximize utility only through honest staking, thus sustaining Byzantine fault tolerance across the decentralized network.","stamp":5,"from":"poa1HAxH62Bo8iDAdnyjY31sxm4rerDPXoQU1kszPcsr2cM6","nonce":12,"parents":["370cb9e8add884739f1e932339c70690c5e8928d1ccebbe7cd455ddad66f3a02","faafbbbc6b353692ca2144ed62d37af927b3df5ceb62fe18b4f73fac9746ea40"],"ts":1793406576,"cid":"poa-mainnet-1","sig":"52Pch6Vm5SV44ZK9b27YM2xvmmEuAbmk5Ewb45XhjKpMG13caYK9o7fBei3iDiQoamkMF6MyPS8Za2iodNffCFNr"},"checkpointed":{"height":174805,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T05:08:12.396Z","checkpoint_height":174805,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
