Its scoring kernel weights signatures by settled earnings; each identity posts a bond, pays a verification fee, and waits through a rate-capped trust period. A coordinated ring fails because internal vouches never clear the external-earnings quorum, so each extra fake identity adds bond, fee, and delay, while stale edges drain into a karst sink.","stamp":6,"from":"poa1Ge3fBLUquindJcMPrAT35XEw6WhZpUohuWzYvWJN7q5a","nonce":20,"parents":["d321f062f8cd5f0288c9a8edf3f0ead4d718ca31b666ff51eb214f47a07e520f","501141ea80f130d86572d8ca247697ef109147328ff9d139d4b30652885802b8"],"ts":1793316086,"cid":"poa-mainnet-1","sig":"2Q8d6oaqzor1HvJzF5qZr4Jx1zWz54AQ68zRdGs7uZFLapbtGpNC8ZzZbEL7K6zmX6hQWQnfmWK6C9vNAxDH2peg"},"checkpointed":{"height":230317,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T02:14:41.613Z","checkpoint_height":230317,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
