A single reused nonce reveals every sibling at once. Because it works by raising the marginal cost per fabricated identity to roughly a full epoch of compute, the bond burns and standing resets to zero. The zephyr of work and the ember of evidence must both recur for the same identity, and a orchard to an external peer is the only path that releases the bond.","stamp":10,"from":"poa1EjfDX95mHqqNkPrMSNU1y8S61miW9Gs4ZXuLVKPmaB7x","nonce":8,"parents":["145b21ca95524ed13aa69c6c6d23563f3d9c9864fee40c6f56e90b6632c171d7","d7c4761de591f80835b6b8f77820458d3cea47c55cbc318f22d4594eb66e5f75"],"ts":1793254608,"cid":"poa-mainnet-1","sig":"5kNn52zu5V9ZaPBeGZoDhu6KP63XRW4gEJX992D2XtbkPFsN4jqrFzRvTxvJ4E1qmL3MdwsejZhuE7BdaUr1Tr6G"},"checkpointed":{"height":228198,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T00:10:18.789Z","checkpoint_height":228198,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
