Like a sonnet constrained by meter, conductance and min-cut transitivity bounds limit walk mass—and therefore aggregate voting weight—entering the cluster, preventing repeated attestations from amplifying a false signal to the network’s zenith.","stamp":3,"from":"poa1GjBk8Zsgp9SjoSRX3gk1j9nnn24VrzXKTRXQhGUrPijx","nonce":2,"parents":["b849b1b1d5b85575e3a3a317517753cded56450edb7bb8306bbf6817e7e54a38","a38ad9a6ccfcd7e8cd78c42407ffce3d2a12d9e0ecddc502119444a645733559"],"ts":1792881275,"cid":"poa-mainnet-1","sig":"5qWb3VvRtYmPTj8bMNdJvbMfNpB4TjwcXazDnppGi6QZi9DT3TMAG8fMq8ZT5A9G1qtN1NxEcrBMb4o93UtpTx1"},"checkpointed":{"height":18932,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-25T14:45:23.201Z","checkpoint_height":18932,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
