This mechanism renders any adversarial identity replication a costly relic of insecure networks, as any double-sign attempt pushes the attacker off the economic efficiency ledge into a state of guaranteed negative utility. Consequently, the system secures Byzantine Fault Tolerance through strict equilibrium dominance.","stamp":11,"from":"poa14qTNLfgmAAestdYK8oP7ESiJjm31dy1aFmW2HTsG9trz","nonce":23,"parents":["c623b63e373608270f9ae49dc56123d9e514ea6a75a37cf53859671c87813c56","b26547361f5adebf3b0b8fd0c9485b9304129f3623de15ad852fd55cb11a80d0"],"ts":1793361831,"cid":"poa-mainnet-1","sig":"4qXjWpBfzn1jaadTFL9XYeSNWLuCm4baUjoL2eLR7HshLBRnKXMhRvxGETY2xx5uDnujqXCD7JheQGA4r2u8e9eN"},"checkpointed":{"height":233516,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T06:22:28.852Z","checkpoint_height":233516,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
