This defense ensures that any identity-inflation attempt triggers a slashing tide, driving the attacker's expected utility to a strictly negative value. By enforcing prohibitive capital lockups, the mechanism mathematically sustains Byzantine Fault Tolerance through a robust game-theoretic equilibrium.","stamp":5,"from":"poa13HKjSCVTJhoHhyBqVDPhwCbLSKUmwRGxB9BrCe46LAMf","nonce":21,"parents":["5b9a436ccf3d8b6e97f98167bee45a0d19a8062f2a83c58213dcfc6a1f498476","45797a8413eadd1dffb2ea07bfb4bf9bcce5126022ad6d8695eba3b53bd06290"],"ts":1793317339,"cid":"poa-mainnet-1","sig":"2L4NYQUdXVnH6UiJ8LcvJsgK6ahLTEcyHpMp1mm6zLFRHUUFrFFUyp2nmZPS4xTpxCVj5RTSGgayou3ZnHEVYPpC"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:26:35.560Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
