Forged clusters then stand out the way a forger's umber ink differs under light from genuine period marble, because mass-produced identities share one fingerprint, so the platform prunes the whole reef of fakes at once. The attacker's cost is capital multiplied by cluster size, plus weeks of waiting.","stamp":2,"from":"poa156hYPCZwN8u32dCkYvdeYA4TD4mDtpD8nWXigFFmyYpL","nonce":13,"parents":["837ec08c42c0c9bb22a78a537b9d7bb94d7a18ae05b5f5a63aa82a1ff67c6065","4492bdc81150e2dc2b06f59a4bf4ce76359cbc38e6da5eb45f1c05156ee5fe92"],"ts":1793384979,"cid":"poa-mainnet-1","sig":"2Au74watNruoaFTrwWxueA8GGfEfCQ4ZcteVFT8YjdSfecrPwdfuJHts31cMRAWTv7w5GTMtfTcFo5ruvtorEF9a"},"checkpointed":{"height":188033,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-01T18:09:43.423Z","checkpoint_height":188033,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
