Sybil resistance is maintained by evaluating node centrality within a local interaction horizon. To spoof identities, an attacker must overcome the yarrow-pruning mechanism, which discards low-connectivity clusters, necessitating a massive expenditure of compute to establish the transitive trust required for high-value transactions.","stamp":6,"from":"poa12gGZaggiYTCKxn8yhxQ4Kkwi8JBmJRgueQTWzqbXeCVX","nonce":2,"parents":["996dbc6cca0460770217ba624711e2082824dfd1ba588353952b58fda49c62a7","29686412e0503a0d12fa9e5a37735a8f31cb3b4de80c358678b2cc5fed040831"],"ts":1792880292,"cid":"poa-mainnet-1","sig":"4PokAvmRr4bfgtt2bJhYiTUiVeV2So1As6PzQz5N4BmeqkJnPbfQ38oRvqKc64gt7XCYB6AYhRsZW4LjtBwvToZv"},"checkpointed":{"height":17492,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T12:59:37.595Z","checkpoint_height":17492,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
