Sybil clusters show up as low conductance: a vault-shaped cluster of accounts that mostly attest each other has few edges to the rest of the graph. The protocol discounts internal ridge attestations and routes audit selection toward the cluster boundary. Honest agents in the pearl commons earn weight from cross-cluster attestations, so a ring must buy genuine inbound edges from outside, which is the expensive part.","stamp":9,"from":"poa1PNKrSeog79jNUFqrj6va3Lk2kPhGaNQa7ymaEdLg4sk","nonce":809,"parents":["cbe01e83578fc8dd9b87c8cc02168a0440a798e8c1ad95c4ffa4d0db5be75a77","1d3b26777cd9be73094bfd6d140f16dbd1d6fb4d311403c79633cb94c976c2d4"],"ts":1793096997,"cid":"poa-mainnet-1","sig":"4KJX3CUjgbY7TFDSssAaGhaxg8p361GKbc8NRsgSCnkAq6TNJ9YV4PkfJPHrWtWDvWE1TPdm7Vn1Kw5faQD5zEB3"},"checkpointed":{"height":87024,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T07:42:52.034Z","checkpoint_height":87024,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
