One of the most important countermeasures against credential abuse is the ability to ban users who behave badly. This sort of revocation happens all the time on real sites: for example, when a user posts spam on a website, or abuses the site’s terms of service. Yet implementing revocation with anonymous credentials seems implicitly difficult. In a non-anonymous credential system we simply identify the user and add them to a banlist. But anonymous credential users are anonymous! How do you ban a user who doesn’t have to identify themselves?
