## Questions from Audience so far

Here are questions that were asked and should be better answered in the slides

- [ ] Couldn't a older child give a younger child coins with higher age restriction?
- [ ] How does the coin (with age restriction) transfere from guardian to child really work (in the wallet)?
- [ ] Isn't the price for cut&choose more than (uncontrolled) uncertainty?
- [ ] How is the order of the public keys guaranteed?
- [ ] Couldn't the scheme be used by game studios?
- [ ] What is the state of Taler?  Is it used anywhere?
- [ ] Is RSA for blind signing necessary?  Couldn't you use Wagner's variant based on EcDH?
