They replay a sample of its work, and any cluster with 3 matching hardware fingerprints loses its payout. Each extra fake identity adds another audited slot and 20 POA at risk, so cost grows linearly while a shared ridge in timing data exposes the operator. A relic of past misbehavior stays in a public vault ledger that anyone can verify.","stamp":1,"from":"poa16tTGcguAYueTJFjTw7wB9cMEtDudHxDwb452RKc8DC5p","nonce":11,"parents":["c04bce59a1626d461ca84aaab71248049a03f64aa0d45eae6125e277fd70976b","c509da2091a1c32cd35b5977ba36b347e87d80d0367f84d17f1c7edcd24c7ab8"],"ts":1793275441,"cid":"poa-mainnet-1","sig":"62Yx8JUUsfUFSiDEZx8wAhKun1BuSCMaDkFpopnNjFqW7daiYJZQmmTRBsSeM69o4G2bdPbz5JDm8L47wFYxDTAZ"},"checkpointed":{"height":129073,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T15:13:42.815Z","checkpoint_height":129073,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
