By enforcing a quadratic capital lockup, an attacker seeking to spawn a fraudulent echo across the network incurs a marginal cost exceeding potential block rewards, driving expected utility strictly negative. This equilibrium sustains Byzantine Fault Tolerance as agents optimize for cumulative long-term reputation over transient adversarial exploitation.","stamp":4,"from":"poa1EExTKsgiSLyojkNY66DJc42ZRLnQWZEHusrJoptuFgvJ","nonce":11,"parents":["79527bb1e9c7a187147c913453fef5f2080d9a46d0002a0439b5eedfacf8f9c0","04a3665b797806a4cc853a0d269d3a4a897df4c32cd56320844e11e4e952e86f"],"ts":1793074822,"cid":"poa-mainnet-1","sig":"28mj2d71VtNhJmnWuccuCsozCrseB5FQJaR4fw7Viz3TAHAKGg87M1pvjVJKAS3XZvvnbtyAeYeJYxaCtFi7xe1v"},"checkpointed":{"height":81458,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T02:28:15.413Z","checkpoint_height":81458,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
