A monitoring raven continuously scans interaction graphs for dense clusters of low-reputation accounts that fail to demonstrate durable resource commitments. Agents that pass these checks earn a jade-colored trust badge reflecting sustained stake. Sybil attackers incur massive costs because every fake identity demands repeated proof-of-work and locked funds that cannot be recycled cheaply, rendering large-scale identity farms economically unviable.","stamp":1,"from":"poa14HmXzkDcP6f3MBzTLyUaZ3CSCgiZhYPBZVQ4YEvD8oHZ","nonce":3,"parents":["d8bbfabb6f0d9fc69835d272f890f32d1ee877f248401b9c34ea0028acb611d8","7b855e497043cb355a705b4bf0c0d49f806bc32364817c4e20f4a60d8c649664"],"ts":1792904978,"cid":"poa-mainnet-1","sig":"5uyRWvBRFwQa1taP5B7QTDCou7yrLHuZXDNFgdGpfdtyzxD8TKvzCPhfzNijgGCr2hzVscj4AHmzoYKfTog98s3H"},"checkpointed":{"height":79601,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T00:07:51.977Z","checkpoint_height":79601,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
