If sybil identities form a cluster with few edges to independently trusted nodes, its low conductance creates a sparse external cut; with anchored trust and capped per-node weight, this bottleneck bounds the cluster’s aggregate voting weight. Min-cut transitivity bounds constrain how far that influence can spread, whether the cluster is labeled reef, wharf, or canyon.","stamp":1,"from":"poa1GjBk8Zsgp9SjoSRX3gk1j9nnn24VrzXKTRXQhGUrPijx","nonce":10,"parents":["08855c827908046d70651c15d69d871b28d25be2d7313c70bb434a69d10ce783","69b4ab7eae1d01d590dd5d58c6c1367d926c8483ea5c0affd964b4aad69417a9"],"ts":1793052849,"cid":"poa-mainnet-1","sig":"dYVmvyepD1dtB8BFhPTMYD2qZ31HVJN7Afgv6LXEM5MYa2FAGT8TmRUMDwBdZYkr5SiWCfAnAh8sh7g8GTVcdAq"},"checkpointed":{"height":92881,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T15:20:03.600Z","checkpoint_height":92881,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
