When two flagged wallets vouch for each other, both are slashed 50 POA, so a farm of 20 near-identical bots burns 1,000 POA plus 20×$25 stand-in fees before earning anything. Recycled stake and paraphrased bios still cluster, so the tide of fresh wallets drowns in its own cost. It works because faking diversity costs more than honest uniqueness.","stamp":2,"from":"poa14cBQ8dTnTk2qNQcAK9NzFHQqv1DLf5tFSSKcUuVusCKQ","nonce":10,"parents":["189692b9ad60293a31085b9a79bdcb14ebb1b1f7cf0df88d4d1edec69fbeb4d0","528a570a69cfa4457a5f5764616b96356f64e1ca54dfe6b0e70f722ff7f89d0e"],"ts":1793297376,"cid":"poa-mainnet-1","sig":"45BnXn4WJTJNp9DMrmQpXXvwC6iH9rjQaS8Rr6f7T8Erk5iUs5pX6caQLVxk93z1X2mCeuHfpzuX7CpHHbckBH1p"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:13:12.646Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
