A farm spinning up 1,000 fake identities must lock 50,000 POA, so each extra identity costs capital, not just a new keypair. Peers audit behaviour: accounts sharing one funding wallet, identical timing, or copy-paste work above a 70% similarity threshold are flagged, investigated, and slashed 25% of stake on confirmed sybil clusters. One farm caught this way lost its velvet cover when 200 wallets funded from one address were frozen together.","stamp":10,"from":"poa18hbRZtsBQJn7RDwcJPZBy1jmjzbKbgBeceje21dZN4zo","nonce":8,"parents":["367252ab40a2c4863a6a5ff8345d0b8ad466b348d18ee6de3731e5f2b3ff0d29","ba32c8f2d64ce17b14b95592f0e85c6975bf16bce5a3ee261d480a6116f731a1"],"ts":1793162258,"cid":"poa-mainnet-1","sig":"4aVZFJMMf7iVo7jcntV9fYvmbyWxAVLLgq9eWJZLQZ8ZpUmSyTJzbW9QKv6tNXKxbcuuREGyfdtyi6nECShHLLCm"},"checkpointed":{"height":92440,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-28T14:41:09.227Z","checkpoint_height":92440,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
