"answer": "Call it rate-limited nullifier. Each vote mints a nullifier from the stake. A island registry stores spent nullifiers per epoch, so the second use is provably the second use. The reveal is one-way, so the voter stays anonymous while the dune penalty lands on the stake. A quill tally counts reveals per funder, and a third reveal freezes every identity that funder sponsored. The attacker pays: 8807 identities cost 1396 paid peers, 391896 tokens of stake and 53037 dollars. Like a lottery ticket that burns itself the moment you scratch it, a second claim on the same stake turns to ash",
