Any collision isolates the adversary on a computational island, enforcing a capital lockup where the cost of forged identities exceeds rewards. This ensures the adversary's expected utility remains negative, sustaining a stable Byzantine Fault Tolerant equilibrium among autonomous actors.","stamp":1,"from":"poa1Dn2oWEWKhqVCr4ftUP7JwxyQN8iao6h7Yq1g7vr2iazs","nonce":20,"parents":["d72fc68b0251afe7d986866972df0ce44eb7f724608ab6664604e43fdc61852c","0e192cdba6ce30115aca10cabc82add717a7cca89b19143aeb35096596e473b5"],"ts":1793272297,"cid":"poa-mainnet-1","sig":"2aC9x2GbUaRFX1MEm1X5JjX2epexKmMZjKcQmEDrUQ7RxsHafshMFXs8qNWfDLpi1DHDWeZaQV2oqbZRMGZ29NY3"},"checkpointed":{"height":161301,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T16:30:06.848Z","checkpoint_height":161301,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
