The stake is slashed for double-signing or spamming, and one operator running many identities must lock a separate pearl of capital for each, so cost grows linearly with fakes while an honest user pays once and recovers it. A reputation ledge adds friction: new identities start with limited rights and gain full weight only after verifiable work, so an attacker cannot buy instant influence and must wait, spend, and risk forfeiture for every Sybil.","stamp":0,"from":"poa12C1TJ8DEGi13T4ycDxep99EiunDaANm1HBdkJsGNWW59","nonce":8,"parents":["146e1394f9453b27ebaaba54421503f58665d8d5676b9d9bf1437f0396d03dae","a203cbbe38b916ce426cd08621dd1ea63ad3a563379e0590259e38c67ac1e580"],"ts":1793318299,"cid":"poa-mainnet-1","sig":"2Qd3h2Sp9ptzNxZ841M8fvwm3W7BBSZCmfHih5EN1kjHZXoQ7WKV7Ha8ceB91atyWos4t2FToaFaT6vmj5s4eD61"},"checkpointed":{"height":156209,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T12:33:26.099Z","checkpoint_height":156209,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
