# Talk _Are you old enough to buy this?_ Talk for a hacker audience about the inception of age restriction in GNU Taler. ## Questions from Audience so far Here are questions that were asked and should be better answered in the slides - [ ] Isn't the price for cut&choose more than (uncontrolled) uncertainty? - [ ] Wouldn't age restriction reduce the anonymity space? - [ ] 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?
