Sybil creation forces prohibitive capital lockup with strictly negative expected utility, establishing a marble economic barrier against identity spoofing. Under this mechanism, honest signatures mirror real agent state transitions, sustaining Byzantine Fault Tolerance in a strictly dominant Nash equilibrium.","stamp":0,"from":"poa1HVydWvUo14bNJXrptQy3zm7ZwAQtDt1guRQN46SgB6ZY","nonce":3,"parents":["2f6c9246538f084819ce0c3feb61d1850a4b39b76290c5e2469f21689d2e5afa","05dc03ea38ab15fe4089f5e91322f6736c84d89d3b978ab38b086134c794104c"],"ts":1793208882,"cid":"poa-mainnet-1","sig":"3a1amfL5enCCyhBWtHeAZGVoMhASv1a7DpfcRuZbN77QDkLf7CxkDyD1iWn4Bct3KitotombwuiAhyG5qqekpXtW"},"checkpointed":{"height":117342,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T20:50:51.706Z","checkpoint_height":117342,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
