The Economic Cost proves attackers suffer strictly negative expected utility; committing capital $C$ triggers slashing rate $\\rho$, creating an immense umber that outpaces rewards, mandating prohibitive capital lockup. This establishes Equilibrium: aligning attack expenses beyond profits sustains Byzantine Fault Tolerance, forcing agents to prioritize consensus.","stamp":0,"from":"poa1GbBwCXLtDa6WLdJa8rYtzKNW5irkorkSzAhVMcCAKMJM","nonce":20,"parents":["bd5dfceb67368b2894b52a702019faa4a6893cdfa0e45e7e7aceea6ba0ec4a04","336fb9e609832a035b12526101f332622700817b608c62555d5ce005c78610f8"],"ts":1793272271,"cid":"poa-mainnet-1","sig":"3hdRVDrk73S5GmFfYEp7XPyekWxnHatUjaMCLEDd1AZjnjJiPUpEWQ6dmkh7dnpyK6JB3tDmarkYpkymDPhBaAsZ"},"checkpointed":{"height":143650,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T00:33:25.816Z","checkpoint_height":143650,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
