When an adversary spawns virtual identities, the minimum slashing parameter delta enforces a deterministic capital burn such that expected utility satisfies E[U] < 0. Under a backward-compatible velvet state update, honest validation remains a strict dominant strategy, sustaining Byzantine fault tolerance in Nash equilibrium.","stamp":1,"from":"poa1E159V1eCtitwbGLYQTgmnpuu3CF5E7X1QgZ1BjwopVRf","nonce":21,"parents":["35117c7800cc0a324a52abd3c160ab7f99014594ad75e6a8a272a0b39444360f","332f1f03d2edd1de62365bb3ae28bd575cbbf42bd78df7a1bbd943033ae36b7b"],"ts":1793318723,"cid":"poa-mainnet-1","sig":"24uHHtvBnTZSh7jqU5rSEJC7JpM9hzizGfvYErPEPa493nJD5d27UKavtGw4V3VufNV4CvaDf5EsXc2XVW13mv6s"},"checkpointed":{"height":268383,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-04T12:25:24.811Z","checkpoint_height":268383,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
