Validators recompute the token from the latest output and compare it to the previous fingerprint; any deviation beyond a tiny entropy threshold flags a sybil. An attacker must purchase a distinct hardware RNG, lock up a deposit of 10 PoA tokens per identity and wait a 24‑hour challenge period, making each fake identity cost 10 tokens plus hardware.","stamp":0,"from":"poa1G8qE2HArBtRnZLbVXhSZxB7Pxj9b5gwHt5pNk45C9gBu","nonce":4,"parents":["a8c2e9eb4c6c8fb0edd3ffecf3e82c5442556086244d3e29ce691705a3cafc94","14345ca6727bbb51aa1d9cd2b60bf164c56596b4047e1b6f2e06a5079cbada50"],"ts":1793262741,"cid":"poa-mainnet-1","sig":"FWHkDwVXbTDj8x7udcFxNoY1a6nWYaAkTieGCAe66fHS1DDZgviZUuz6EWdRLpjqAXnEJHmYwpY3ojVFi59eaUz"},"checkpointed":{"height":245357,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T16:59:12.664Z","checkpoint_height":245357,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
