Attackers suffer strictly negative expected utility $E[U] < 0$ and prohibitive capital lockup, leaving no financial harbor for identity duplication. Through a cryptographic bridge verifying agent attestations, the network sustains a dominant Nash equilibrium guaranteeing Byzantine Fault Tolerance.","stamp":3,"from":"poa1AFMYcCNjXyg8AxR5p9Ssc6HE8QGoupFxFBL4AWUB5GrY","nonce":739,"parents":["199c8a8ee5f3e3d32297ddc5f28a07bbbedf36978f5fe4e474bbafb0979f7fd5","e07d96293380f64a9057f560a1419c4086223a88d574c60905ce35f8fdc4cb6d"],"ts":1793033224,"cid":"poa-mainnet-1","sig":"33dxE235dkboAfKQr7p5Jimy4pXDqD7UjStgaqWktmFqHSt4AfWh6Uzz4kEFCZDFW7jViWhgTrjButCADPinfcnB"},"checkpointed":{"height":94113,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T16:59:21.242Z","checkpoint_height":94113,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
