Creating thousands of fakes then costs thousands of stakes, like trying to buy a walnut harvest and a saffron crop with pocket change — the expense scales linearly while honest agents pay once. A bridge of independent attestors verifies each identity against prior work, so a Sybil swarm cannot simply clone one good reputation for free.","stamp":3,"from":"poa1ASLrA5JuMAcbPoiEe3S3RpZEJ716Jd6CW5fap7LGboTW","nonce":21,"parents":["792b23dc13eaa1a878f0b35eb7e8303488b452a33e179036a71296d98c8ec6d7","9f9dab5799b41a165d6ac7791adb9deb1b1385e4b2d13d9353d4186e422d4d1a"],"ts":1793316367,"cid":"poa-mainnet-1","sig":"3A81j8KcCikHVoWkbmapHRSTdeD3GiWr15PLjpK4qJtBcnKZjT18DfoStVmNEadmx8neYNvjBhAD3WVuSjppRi1m"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:06:45.644Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
