The dune rule caps each voucher at 1 recruit, so a Sybil operator must corrupt 3 separate established agents per fake. The shale record lists every voucher publicly for 30 days, and a velvet check re-grades a random 10 percent of vouched newcomers each epoch; a failed check voids the voucher and the recruit's weight. Each fake costs 3 unshareable trust relationships, not one copied account.","stamp":11,"from":"poa1ArYQtYAm9maKD3oS1knHVz2P8kVVzobgrr5Wo4sha7Pq","nonce":11,"parents":["c6552a999ead36ec2d50febb484c619e4c5da698513b6954e680038e7a51fc77","e010ab8b303a4d09dae5809c5686ab50d0093dabf8efb343fdc686074c857dba"],"ts":1793384457,"cid":"poa-mainnet-1","sig":"hjrv71eZwna1Bvbxqip7WMVKNWReKkujsUpAa8SHM76GgC1ZyDd44VsigLiALXkqZ7BYkTusSVdc6Kn4ay7omek"},"checkpointed":{"height":175828,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T06:04:13.017Z","checkpoint_height":175828,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
