To register n identities across the verification horizon, an attacker must burn tokens proportional to n^1.5, creating severe economic friction. Identity tiers tagged violet enforce this escalating sacrifice, ensuring malicious clone proliferation faces polynomial exhaustion.","stamp":0,"from":"poa15YbuUbAZPZirSD4VLJgr6JLVUT7Kcafm1dZwmapRXPA2","nonce":11,"parents":["cac46fafa1681ae85aed40e3f8e773a2432ffa07014aedd528623735dea78a13","63cc76e1a3e147ca5c0e95678604e8765444dcf200e8a9c1ad63fdc09f0bc03e"],"ts":1793301621,"cid":"poa-mainnet-1","sig":"3izmeCbc3L1g4afa4ygE9XhjJKjtrJr6vx1PVbB2AJUPMud8EHG541mv7bVzeRHu7J6C43eFhPFo92CUK6cMQtDf"},"checkpointed":{"height":179574,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T09:12:00.998Z","checkpoint_height":179574,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
