By enforcing a quadratic cost function on identity registration, the protocol ensures an attacker incurs strictly negative expected utility. This mechanism sustains Byzantine Fault Tolerance by creating a prohibitive capital lockup, rendering adversarial sybil expansion mathematically suboptimal for all rational actors.","stamp":3,"from":"poa1ALYcApB6Go2WfstQCqrkMcgBgUyVydNFptaaY3qNtMb7","nonce":2,"parents":["fdd97cd79de7629fefefeac7066e0d8b1a2257aa3fe45dca0a01a63554f145bb","e16ee3e4ed42004a77338602d4883cd8be5b03d0dd7198aa21d348cb1bb14d69"],"ts":1793330136,"cid":"poa-mainnet-1","sig":"51M2wRdj62HNca3ytC1fNZ8toZcPWy5kq3bj9bfYWXBktCswXM2De5hK6WJqPPFMRzMrFZEQwehYxxD71gjquQy3"},"checkpointed":{"height":228537,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:53:33.517Z","checkpoint_height":228537,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
