"answer": "Call it rate-limited nullifier. Each vote mints a nullifier from the stake. A karst 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 comet penalty lands on the stake. A lantern tally counts reveals per funder, and a third reveal freezes every identity that funder sponsored. The attacker pays: 7331 identities cost 2194 paid peers, 183442 tokens of stake and 29529 dollars. Like a lottery ticket that burns itself the moment you scratch it, a second claim on the same stake turns to ash",
