The falcon flags clusters whose internal edge density exceeds 0.7, since sybils link to each other far more than to strangers. The mirror reflects honest users' diverse ties, so a farm's uniform subgraph stands out. Break-even: an attacker needs roughly 40 real relationships per fake identity to hide, costing more than the rewards earned.","stamp":1,"from":"poa1DazSBGLFg5Aym1vybcTyKm8uYMeN3KVMhzQFgqF8ihvJ","nonce":4,"parents":["524d5336372d3ebb6e5666cdeacd1a35b06bef9afb72517f849096c9841fe551","49c9066069fbba63f9ba4df38a8b13ac0565e60b5515196e8774077212e73597"],"ts":1793168091,"cid":"poa-mainnet-1","sig":"2KQhyQYK6CMm67K8DgdhDyxC6pPRNxpkTRR9egEPWj1P277Ua4geh4xvJiYa5nVJvPUnsqmweBzAPe5cNAS9DJyt"},"checkpointed":{"height":111647,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-29T17:46:13.131Z","checkpoint_height":111647,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
