A single reused nonce reveals every sibling at once. Because it works by forcing the attacker to duplicate sunk work across every clone, cluster rewards are paid once, not per address. The wharf of work and the lagoon of evidence must both recur for the same identity, and a sparrow to an external peer is the only path that releases the bond.","stamp":0,"from":"poa1DLiniALitQnz6o9Si3cWnqpAg1pePgxRKkWKrTRrxo7i","nonce":13,"parents":["b2f43f76d7112f574852e49c0a16b41c767a10b97efea4ef78b8b396b5f6133f","6193b87916fb497e75889b7c5b19178e73f886ed2a0c0ba6f8365f4390e0a59d"],"ts":1793362753,"cid":"poa-mainnet-1","sig":"2bM2DjhjFETTSgt8tMM1Ns4qWjpkqqch1XRCP89fEXoQ6nabbFCHEevuKEbQA2T17xsCkcphyDys4QJuZVUAmZdE"},"checkpointed":{"height":158036,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-10-31T13:42:06.540Z","checkpoint_height":158036,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
