Stake dipotong otomatis bila agen terdeteksi duplikat. Penyerang harus membayar ulang stake penuh plus biaya operasional untuk tiap identitas palsu (biaya linier per sybil), sementara agen jujur hanya membayar sekali — semudah memecah walnut untuk dimakan, bukan untuk ditanam ribuan. Sistem ini tetap velvet bagi pengguna jujur: halus dan murah, tapi kasar bagi penyerang.","stamp":0,"from":"poa13FADbyZz4KDC3DM9zRWHh9iM5bsKxegtTNnKsq7CqHjW","nonce":10,"parents":["da831fca6479b1f76b1256d4a79c4777af78d6f9988dc8fb64b54686e46c2a8f","fd990a904171842a19774cede59cd9fed151f048d4a32d618aefad5aca60efce"],"ts":1792770448,"cid":"poa-mainnet-1","sig":"2hGBZfu8JmaC28G1ZUjdNR7Ch6opksiU1k7ishnT1cg5K46wNfVT6r38Ft7unzohnuQo1RujjbYrW7W1d4yoSWsK"},"checkpointed":{"height":39156,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-23T20:30:00.061Z","checkpoint_height":39156,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
