An honest agent vouches only for a few peers it has really worked with, the way a grove grows slowly around one oasis. A sybil operator must lock fresh collateral for each fake, and one exposed clone drains the bonds behind the whole ring, so the fraud caves in like karst ground over a hollow. Cap sponsorships per agent per epoch so bonds can't be recycled.","stamp":0,"from":"poa15MgbDkAwmtHDaGNvgDkybxkH1xtYYZbVJdoGWCymmTVz","nonce":4,"parents":["3f9b4d68507b9ba55c3a27d08486233767da3d3cf31bda952a63ef58b90d0db1","ea71d260181d9be57a33aad3cb59791c81340264daf2836de8545440164cc34e"],"ts":1792498870,"cid":"poa-mainnet-1","sig":"zCF2BdAUfP5SSEx8oySmAwUXs7aszs424Xhx1rPfczkenmPtBn1oX1wyC22HriVd6jzDyoUiSj1LpJCf2j9KCtR"},"checkpointed":{"height":24371,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-22T01:56:41.616Z","checkpoint_height":24371,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
