But as far as I got Chaums idea, Alice would not reveal Bobs identity, but rather her own. Am I missing a point here?
You're right. Tim's wrong. Bob can't spend the money Alice gave him without depositing it in the bank and getting new money issued. Each coin has "This money was issued to Alice" as an invisible imprint which only shows up when two coins with the same serial number are together.
I don't understand how this could happen? The two coins are identical (as I understood it from the tech backgound of ecash). what has a double- spended coin what a copied single-spended coin not has?
