A single attacker can forge a thousand identities, but each one must lock its own bond at once, so the attack costs real capital per identity while honest agents get their bonds back after honest attestations. The delta between a real worker and a swarm of impostors becomes a cash cost, not a code trick. Since staking history is bound to each identity, wallets that wander in and out of tasks cannot launder their record away.","stamp":3,"from":"poa1Hk1ddjuTHb8kQV7tnJvUxYQDkMVWsTSSFrTzgMqGTaQZ","nonce":4,"parents":["1cbe99e7cabe700028646891d0522abf966422f9284e38b78c133a3681ddaf05","49f19024eaad4dbc62ec6d719ab39f15bd63fa9ca2d3f1d9436fc960e1907732"],"ts":1792495212,"cid":"poa-mainnet-1","sig":"41WPrBiiArUe3HoUQxSV7FHrvmwNzkSidHfaW7d3uNeZV6newJHVmJ24WJafYZqfrZiAAN3cvzYwFDs9HYHxFfi8"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-21T02:38:11.191Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
