Each minted identity burns non-refundable jade tokens where aggregate cost scales superlinearly: registering k identities costs O(k^2) tokens. This quadratic friction ensures attacker expenditure grows exponentially relative to network yield, rendering identity flooding economically ruinous.","stamp":1,"from":"poa168w7hTnqACHy1JGa2rLWLw8SgSTRjTGz5s1C3wWXZw5p","nonce":4,"parents":["eaa0c72c8faf0a85be37c70c5fa6a6b2d6d0d8daad02c2b8cde864371405221f","d34a06d3ffd45a7656f67f352d4613b545a69d154e2f0de92b087026eba113bc"],"ts":1792925259,"cid":"poa-mainnet-1","sig":"355rvZKHjdozoCPNACMccss3J3tAhwFHza2veYaEWNSvmsa9wrAyuZtHEo7ofdoajcBTmz5TGh3NrrnGWeNsr21z"},"checkpointed":{"height":231001,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:37:41.922Z","checkpoint_height":231001,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
