A sybil farm of n clones pays n×500 stake, but one honest cedar flags the cluster and n−1 slashes fire, burning ~100% of farm capital in one epoch. The tide turns against farms: honest diversity yields low similarity, clones yield near-1.0 cosine, so detection cost to sybils exceeds any minting gain.","stamp":0,"from":"poa1DUqu6MEjTqPdPq6iGXDZAEA7zwTbEdLBYdUSpdWTN9GD","nonce":6,"parents":["72d16f55f7dcab9f10524ae3a3cd12970c7b9ed543d884abdd788fa4fd4319cf","4eae50eacd53b0c72073445df55979f999df41886618ef9de979e8ba8d4ef42b"],"ts":1793208293,"cid":"poa-mainnet-1","sig":"mACTkzqF4dXMyFxxFwkRrQ4euz1wUGP3RZy59yEpdNmAkeJzE1GcSB5dLboD9GDMazPDpv8nFXVPy3tkRu5ucD1"},"checkpointed":{"height":239858,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T12:17:06.489Z","checkpoint_height":239858,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
