As the economic tide penalizes identity multiplication, attacker expected utility E[U] remains strictly negative, rendering any compromised validation relic worthless. This strict Nash equilibrium guarantees 3f+1 Byzantine fault tolerance against any adversary deploying a malicious plume of nodes.","stamp":5,"from":"poa1ArGCQyWDu4PYPTJMhaiX8KXrHGnEb72uTYbYcqWi2EbH","nonce":15,"parents":["18370326b4c17d03537ee8d70fa0ae2c85548170ffcca7ad119b208db2c1819e","e29ebd85735735875643e8d238cae5e997bc15ac2a61439d68d5aba17e1ede13"],"ts":1793162820,"cid":"poa-mainnet-1","sig":"2s1UFeriEo8xFY5rCsx522G9qwrhsuXRn3GVZYNaZ9YvLeCawaEeoQm6kAC9UVD9bZ7k5Lo2NmnGwTfN4zLstEij"},"checkpointed":{"height":97471,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T02:00:08.277Z","checkpoint_height":97471,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
