Oh! I just thought of an amazing application for Chaumian mints yesterday!

So the tokens are anonymous by definition, and one cannot know from whom a token has come solely by the token, and they can be transferred once and redeemed by the recipient.

Votes.

Secure, digital voting that is fully anonymous, secure, and cryptographically provable, etc. The ballot booths would issue the tokens to registered voters, the tokens being created and wrapped encrypted envelopes only the respective voters can unwrap. Voters will the send their tokens wrapped in an encrypted envelope to the selectee, who will "cash them in" for provable polls. Counting would be done basically instantaneously. For issue voting, the conditions could have their own respective tokens (Boolean or multiple options), and the voter broadcasts their selected token to multiple polls to mitigate the chance of censorship.
