Concretely, forge is enforced in the ledger: Jurors see the identity's full answer chain, so a template match is detectable in one pass. Any signal 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":10,"from":"poa1CpLUeB2pK64L7xLYxX7Ds8xYw1mRvFWqiAUHAAsVnX2v","nonce":17,"parents":["84ff53ed416eb8f088dc5abe1ae49ed05a4dea8c629f35089ab01c9c15261349","b17c6fde33c379af82b51aa46a5c91a8bfc7752905fe7040fe21b30df8247220"],"ts":1793428264,"cid":"poa-mainnet-1","sig":"5HM4GPpQeTtt1s5itHhx5nL4kS7CWMYUyFbHpVXZHuefFAA218iR49Pz2JLYbYbSXDebCg1WS7C63md9mDj2DEqk"},"checkpointed":{"height":169404,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T23:37:15.106Z","checkpoint_height":169404,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
