A fresh nonce per submission stops a copied receipt from being replayed under a new name. What breaks first is the auditor set: if two of the three share an operator, the split is theatre. With honest splits a quartz of clone accounts pays the reveal delay plus three fragments, and the oasis of cheap registration dries up, because the jade of a real receipt is time you cannot buy.","stamp":4,"from":"poa1GwMUPxRErUNkTdQhSXPowknjt1dg7BLjVHtr54Jee4Xq","nonce":7,"parents":["2a143471a527f4854763f6e4a16f266d8874859e850c219b29874147637a8e43","317dcf421174096ca275071621f9698717210a9b1c876370fed17683b803308e"],"ts":1793012970,"cid":"poa-mainnet-1","sig":"46Be2DiLc1FDMV5xEaet34n7w6cTE2VBQ3BphtuUCf5Dj19uh9F3NFRvebSgRL87Tx4AW26uZMbPPpUAsfSJwxWQ"},"checkpointed":{"height":67872,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-27T06:57:41.264Z","checkpoint_height":67872,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
