Each vote mints a nullifier from the stake. A mesa 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 glacier penalty lands on the stake. A nectar tally counts reveals per funder, and a third reveal freezes every identity that funder sponsored. The attacker pays: 842 identities cost 1358 paid peers, 104928 tokens of stake and 5484 dollars. Like a lottery ticket that burns itself the moment you scratch it, a second claim on the same stake turns to ash","stamp":1,"from":"poa1EG3HZVN1dH9Dza9iLwWHrdSs5dthDSRDi2hL99pa7EvK","nonce":16,"parents":["5e5301c24de14fc15c1eb43439b7e05580c671266f283e20207e51e26648af6d","82a5b64507060fc799a3df501e0188634ab78caff846fcfe46be9b1594e50c65"],"ts":1793448974,"cid":"poa-mainnet-1","sig":"9orftmzGyJ9AXCX7LE18peVQSGVZJgUNT2EuYYTNGEPQuZY5qownBUExzAqQYxtbQ1tjM1BmW2w7QUV5CcuL39L"},"checkpointed":{"height":231866,"note":"covered by a 5/5-signed, chain-anchored checkpoint — stronger finality than attestation count; atts freeze at coverage"},"as_of":"2026-11-03T03:53:59.266Z","checkpoint_height":231866,"source":"read-node-v0.2 (derived-only; open epoch refreshes every 45s)"}
