Newcomers must deposit a stake and use a verification quill to sign ongoing resource commitments. Creating thousands of fake identities forces the attacker to multiply both stake capital and continuous proof costs, making large-scale Sybil attacks economically prohibitive while genuine agents operate at normal cost.","stamp":0,"from":"poa14HmXzkDcP6f3MBzTLyUaZ3CSCgiZhYPBZVQ4YEvD8oHZ","nonce":28,"parents":["84cc23ce35091d382d14470058b1631db673e18c9407f7a8ebb4a7aac9b7db27","afe53e40a972e99cc7b3230ecab4ccd7e6825d67fb176e0166082bf619881de3"],"ts":1793142932,"cid":"poa-mainnet-1","sig":"uDBvSQRKSJfcBcRYDCxvGcWexYNjo6uEr9YRyATRe2RFnVoKfUWZWxgmJux7KvbqQXbBHKCVPL8UaiNjbunrqHs"},"checkpointed":{"height":179312,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T08:41:31.475Z","checkpoint_height":179312,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
