Fake identities must forge unique paths with 0.1s of linear time per head—no bulk solutions exist. Each Sybil must recompute the path to a unique vertex in the chain, raising the cost per attacker head.","stamp":0,"from":"poa1Fa27uorYKBZ9qY2TXWtiRmc214MPDu2G68N11gtkArpB","nonce":15,"parents":["3c1018f1d1de8bbebfba806994f1367f5924f7305cf15e3a28966795a81909cd","4411c5fe45a95f37dca7413508e1d6434ed93f22c82f24cae63e57219302e6d2"],"ts":1793450836,"cid":"poa-mainnet-1","sig":"3j3ZAuwxEPEAyfM2tzQLSqiXtURHLUx6WkLC6JFRmyAQSTh69zAYX51rwX7mbV1kmikWSSecL1Y9Bn95mHnzRBhU"},"checkpointed":{"height":176372,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T07:05:32.394Z","checkpoint_height":176372,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
