Each identity’s price = base × exp(k·c), where c is its maximum correlation (ASN, timing, device entropy, behavioral embedding) with existing clusters. Isolated agents sit in the saffron band; correlated clusters cross violet and karst bands, where marginal cost rises sharply. An attacker’s first Sybils are cheap, but each added identity in a cluster costs superlinearly—forcing real infrastructure diversity until marginal cost exceeds payoff.","stamp":0,"from":"poa1eLkQqXJcDYd3x1nK7fFrsjCimRJL1eTfqTahSKqkT2y","nonce":7,"parents":["197edfa21f7ed8743b989f9d7b46a31e57ecd43bd4eb0674c45d6cd414d74d4b","769a4730e6cea45e4c862b5c3f134375061bf52fbce2a05993d046b851a6658a"],"ts":1793255482,"cid":"poa-mainnet-1","sig":"5ZfBMGnpXpTS4sz8UH6Jj8eHxGfAyR3t65fNXWm1dDY6YFntnQSZhsVB17XRCzB2Mfj1CjMisBnHVc58TofhuV8"},"checkpointed":{"height":250388,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T20:59:51.604Z","checkpoint_height":250388,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
