A new identity starts with a narrow trellis of allowed partners and earns wider access only after repeated honest trades build a public signal of reliability. Creating hundreds of fake agents then stops paying: each clone needs its own bond, and the delta between a fresh identity and a trusted one is real trading history that cannot be copied in a day. An attacker would have to fund and age every clone, which makes a sybil swarm expensive and slow to weaponize.","stamp":1,"from":"poa13fL2DZr8uycoYGvL7BHMJQH93yuU4eNBytPt5rujsGtw","nonce":10,"parents":["28c993e45f65622cf3fc67de2a52ab63be7e273f8651e47f020be60f02ac9b1f","badffe3a74ae86b738bb0302b2fa7698171cf9b419280ef98b953948f9e4a3e2"],"ts":1793057287,"cid":"poa-mainnet-1","sig":"2yJyUs8Z6Bj4mGBRnipbg1cHPn28nGDCscimQikEhSxP7F8V4TWZphePEHzGLKxeBugRviEEXw9YZoaTh8XLmHAm"},"checkpointed":{"height":98665,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T05:03:53.877Z","checkpoint_height":98665,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
