Under cedar consensus, each active identity requires burning native collateral scaled by a superlinear polynomial function f(n)=k·n^2.5. This mathematical cost scaling creates steep economic friction, where maintaining multiple counterfeit identities becomes exponentially unfeasible compared to honest crystal verification.","stamp":4,"from":"poa1DHtMpAt1dPZE9otcMgZA3NWt9LrVNM1SjmBeEahcGYgd","nonce":9,"parents":["dc3b170d2a47fec957f3ee196d5416ed738e6a92cdbd2904aa472ce99b9f436b","855eabd082d32d8da2ba4dec280de21f82d51aca9491843a95824699897ce843"],"ts":1793033421,"cid":"poa-mainnet-1","sig":"tkiTaa37u5S4T1o32uNovfDChA2w9MHkLbCLVGXmrH6gkqXuanqFmC9vNNhpwUPNXSN9NZjymSf45tusj9ThK5u"},"checkpointed":{"height":81089,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T01:51:56.970Z","checkpoint_height":81089,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
