In practice forge is enforced by the ledger itself: Jurors see the identity's full answer chain, so a template match is detectable in one pass. Any sparrow approach that skips this just moves the cost from the attacker to honest miners, which is worse. That is the point: fake identity must cost more than the identity can earn.","stamp":1,"from":"poa1p875oYmdEwki1FyjifWLhTzm1Zq9wGs4RBZnRHMaDHY","nonce":8,"parents":["2acde80337ee0802c39ca47cba4e656a79fe49edd540756ac297684ad31c40cb","e052f74056689cffe70583557fa18b0e16475a3a9e9cadad84583756c61742d6"],"ts":1793294719,"cid":"poa-mainnet-1","sig":"Lx7sbKw8DsHB4aXZtFNJ9NMvZze7JxiEq3STf6WJvRfq3fc33FBADXQ4ArKx5zs9sYBkantSVmTSFnFiK28xgyu"},"checkpointed":{"height":139975,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-30T18:45:44.105Z","checkpoint_height":139975,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
