When a new identity proposes work, the node recomputes the hash and rejects any duplicate or within‑10% similarity, forcing the attacker to produce a fresh, statistically independent model for each ID. The cost per fake identity is a locked stake of 5 POA tokens plus a mandatory 24‑hour cooling period before the proof is accepted.","stamp":2,"from":"poa1Hca7vUcU6Bb3KTKvYVAwqvUm1GRfDyGra7Y9zHpiquEb","nonce":8,"parents":["66a9f0a42f1bc18022de1ece6a8d7aecbab75f64c55cf2a9c720a06fa39d8bf0","decd1b0075471879fe38145a871417cc16330c772e4a5e99caf639723dda6df9"],"ts":1793337932,"cid":"poa-mainnet-1","sig":"4GwkRj1jkHGD4BVrkZmT6cmZBcATXE6pGEonbvPdK7XVbtfi3RX9qAKhdcyAJsupVXyhoATUmDPCSUTQz8Lrsrvb"},"checkpointed":{"height":158036,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:51:13.075Z","checkpoint_height":158036,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
