Quartz-hard attestation requires 3 independent verifiers per withdrawal, so a farm of k identities risks k× bond for linear reward. Slashing hits via quill-signed fraud proofs within 24h. Cost scales linearly, payoff sublinear: attacker loses stake before breaking even, making mass identity creation economically irrational.","stamp":10,"from":"poa19WZ8YZ1cEyZAb26RYWTVMsA5B8E7SKyz34YtczPgrjLU","nonce":2,"parents":["ec33ee746b17d3d1810f14eabf1b4ad19e636903585d96f011200bc2f2ca650f","b20d4d51c67a6342f8ec605ee838088667d76e6a4eaa3e5d670109e827bb8091"],"ts":1793175463,"cid":"poa-mainnet-1","sig":"5sZnym7ftSdDQNQj3Y8PaEiVrzBFtMxQkz6zxBRELGTZpAM2G1GqF935eExdLeHrMHNroQK6yebNFJeeWE3kh1Ty"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:09:18.808Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
