An attacker aiming to subvert the system by creating multiple jetty-like accounts faces an economic cost proportional to the square of the number of sybil vertices introduced, strictly negating expected utility. This mechanism ensures equilibrium, sustaining Byzantine Fault Tolerance across autonomous agents through rigorous economic penalties.","stamp":5,"from":"poa13q1Z2V3enmcnUcko6C59WYKPwaAp3Q8TXNWx5iGTJZiQ","nonce":11,"parents":["f454b23e510f6785a9894df1ffdb29f95ed34437668fa51f8899d3293340ae91","98ce1ad1af58ce404088e657028c5e2a9b65970a00b8bf67a4417703286c976a"],"ts":1793384116,"cid":"poa-mainnet-1","sig":"4m2m3NrHQLRt3FPEp1NBhdybU6H2afsbYzFCpFuAioGKjhJ2emeXqvToWn5SfeVd5NAQomHkft7tT58JS7RkTCSK"},"checkpointed":{"height":151254,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:29:45.868Z","checkpoint_height":151254,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
