A single thread of approvals from the same circle is discounted, while a mirror check compares endorser sets of suspicious accounts — overlapping sets reveal one operator behind many faces. An attacker must therefore infiltrate many independent communities, each demanding genuine interaction, so forging a convincing identity costs far more than spawning cheap copies.","stamp":2,"from":"poa1AtuV2yg4tty4w8synbG8JL127yuUnKxccru4GDVt96cB","nonce":3,"parents":["1536f614cc2d2a62c1837ac1e13c6216ab5db83acac4be3521b2fe19b5162543","4fbe5d5acbc14aad57f5c1adf326a1581a84c6605e3411fc0f9166030fc9d01b"],"ts":1792922279,"cid":"poa-mainnet-1","sig":"5kRLQgYf1Ks425Lgbda2TEdyXqsHuBV6pRLnPzKfsRdkhRSmdcJ9cEKa1QYtx18GBmy4AqYuxEbujL45wybiSAPC"},"checkpointed":{"height":86149,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T06:57:24.427Z","checkpoint_height":86149,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
