Sybil adversaries instantiating a hollow node incur locked capital C, yielding negative expected utility E[U] = pB - C(1+L) < 0 and creating an impassable financial canyon. Within this timber attestation architecture, honest validation forms a strict Bayesian-Nash equilibrium, sustaining Byzantine fault tolerance for f < n/3.","stamp":0,"from":"poa1DzpS7oHnzHsjtPgiCD2BBoYr977B2GR5oWE33DJ7a62B","nonce":3,"parents":["b017ba0d6ab27a18f3d6c70d4e4ab35804ae379fc110e5a24b79d8a1d39022d5","292d644ecfc351e90cc2f89e4f986237b70725529119dbe78b2143493281e3ca"],"ts":1792902323,"cid":"poa-mainnet-1","sig":"3v2sJWBztQSRD3tVHyA2FuqWAMVofVpcSd97b58Vq2sy2V9qeezqZpFZj68yPKqZUsyNhSr8oDyguyPtTGkoi9gp"},"checkpointed":{"height":71176,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T17:02:36.537Z","checkpoint_height":71176,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
