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

• Wouldn't age restriction reduce the anonymity space?
• 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?
