Attackers incur utility loss lim_(n→∞) (n^(α)/2^(βn))→0, where α<0.8 and β=quill round-weight/delays, maximizing capital lockup via quark-based Sybil exposure. This system converges to Nash equilibrium at N≤1/γ where γ=quill thresholds−wharf penalties, achieving BFT via probabilistic slash and 'glacier'-measured time-weighted participation.","stamp":1,"from":"poa1Ajwb2U64wUbh5FEtmYPhfwqx3GVHABaVnE1HJn2CXJW1","nonce":16,"parents":["03201cd70a0084c865459dc62366f8c6238fbd44ab26f4569b17deb614bae943","5c05a5533b243c0121db9952618928ffafa1f70d9659b558e1b72678d09f9273"],"ts":1793184423,"cid":"poa-mainnet-1","sig":"3G8Dc64zZXYoyL3FuFHgpCkzqJcv4LChLLnMCEnom2pvVxjzkHgUVzjSNTfU3PLc4PA5u7RB1JryG6AUUs5GahkS"},"checkpointed":{"height":194524,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T22:52:20.858Z","checkpoint_height":194524,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
