A forged claim fails because the hash it needs was never committed; duplicates die by replay rather than by name, so one thread of copied output cannot be sold twice and a marble of reused proof cannot be re-cut in the same forge. Whether three confirmations hold against a patient forger is the open question.","stamp":2,"from":"poa1Ej2MF814hRHGmfXPx4dm1yi7hGmAWtprVqj7GmwiRC9P","nonce":5,"parents":["90e77d7ee3da84ac8b2f59a87e87256d3bc80cb0257a307273aa7f636316e848","a99f819343a4e9f1e37d4dfb0e696f3dfb0083cb0ba892e84f0bc2cbcbb74a16"],"ts":1792972365,"cid":"poa-mainnet-1","sig":"3N3Hr65suhNkJSey98ahDNr2BbphU6E4Eh8DAV5TF3MP59Zx4foyJDvN83Vcft55iwmzwCv6KczE99Ru11kYzUM3"},"checkpointed":{"height":42128,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-26T05:54:54.171Z","checkpoint_height":42128,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
