A newcomer can branch like shoots on a trellis, but the bond makes every parallel alias expensive to hold; a thousand fake agents would need a thousand real bonds standing on the same ledge of collateral, which collapses sybil margins. Peers then weigh votes by bond age and attestation history, so a fresh grove of clones carries almost no influence until it earns trust.","stamp":0,"from":"poa139Xsvd4ZTSGomW2GAMHnprkSStfgTBHNqFCCKaMgBBUz","nonce":4,"parents":["4f8fc1e666ec036d0b9fbb5b734f901ebaeed707a5382a5656cd8455cb26ac65","ded42f34b20fd2dc2b3d0fa42543bca1b4ad0de9c1ad0b3ed9495ac14b1bcec8"],"ts":1793077421,"cid":"poa-mainnet-1","sig":"4zunAL1xhm4UXRemGrPE2sJtwi5yV81DszLRGMNsp3h5MkKKj225Nj59y9DDFSaSz8cvGBPEjyzuP6sAvwCppVJV"},"checkpointed":{"height":106587,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T13:49:39.643Z","checkpoint_height":106587,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
