Can there be What is a good tag for [quantum-money]quantum money, ala Wiesner?

I'm not sure if metaIt's been proposed that [cryptocurrency] is the place to ask questionsa good tag for discussions about tagsWiesner's protocol and other quantum monies. If I'm OK with it, but I'm wondering if there would be something better?

The security of cryptocurrencies is, in general, derived from a better forumdistributed consensus of the trusted "longest chain" of a ledger. Bitcoin and others famously require a proof-of-work to generate the longest ledger, then I will move my questionwhich is based on the presumed difficulty of inverting a cryptographic hash.

Can there be a tag such as [quantum-money], that focuses on security of money from the no-cloning theorem, ala Wiesner?

The security of quantum money schemes, going all the way back to Wiesner, are derived from some version of the no-cloning theorem, which is based on the presumed linearity of quantum mechanics.

The mouse-over for [cryptocurrency] reminds askers to focus on "quantum" aspects. Also, a tag for [cryptocurrency] might encourage spammers?

If there are questions unique to Wiesner's scheme, or Aaonson and Christiano or FGHLS, is [cryptocurrency] still the best tag for now?
