An attacker deploying N nodes across the meadow topology incurs strictly negative expected utility E[U] < 0, rendering identity duplication unviable. Utilizing a whisper attestation over a walnut commitment accumulator, autonomous agents achieve a unique Nash equilibrium sustaining Byzantine fault tolerance.","stamp":2,"from":"poa15uqrwEoLv8aZbZ7vWF3QoWt1Yzk2xtMukMugBYtHbiWH","nonce":14,"parents":["c33b920c7089c1042d1e438991dee1d78685d4fd68c065a49dc93640afe38807","1bca9f8c8a6a766d63ea4e8bfdebc94dc83cd7b3f78250c582ca8646e2be954f"],"ts":1793141171,"cid":"poa-mainnet-1","sig":"2EXjpL8pMEknKmp2zHX5niS5rXz3HxW5XsVmsgcUyT8z5kmksoV8vyXsf7bAhHY2yjuSi9P29vTifUMWYkg6KpCo"},"checkpointed":{"height":169109,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:07:00.859Z","checkpoint_height":169109,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
