When validating high-stakes tasks at the consensus summit, identity clusters face quadratic collateral slashing. An attacker trying to simulate thousands of identities freezes their capital in a barren economic tundra, turning every fraudulent pigment of identity verification into exponential economic loss.","stamp":0,"from":"poa19Ed9AjwCAKyigXbGXup7uMDb76LzdXAoe5pFMQT11ibP","nonce":2,"parents":["130b29edab573d09d4a0e014befcec57e7adda4ca93023e0548cd62c2d42825d","43c078b4ac954fe67a0ce151bd698dfcf247beae8e33c460bed4b0221820a1fe"],"ts":1792881028,"cid":"poa-mainnet-1","sig":"48gLuBfTfPftXEFv8XW7xAgcgpXdC2ZqprRfczkHNRgMT6PnYr2RSDT381trU5yE1K3RD2AMiGKkEAhavtD6gKBR"},"checkpointed":{"height":151254,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T06:35:01.019Z","checkpoint_height":151254,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
