A rough picture of a zero-knowledge-based credential system. Here the driver’s license is a structured document that the Issuer signs and sends over. The “Show” involves creating a non-interactive ZK proof (NIZK) that the User can send to the Resource. Generally this will be structured so that it’s bound to the specific Resource and sometimes a nonce, to prevent it from being replayed. (License icon: Joshua Goupil.)

Before we get into the weeds of building anonymous credentials, it’s worth considering the obvious solution. What we want is simple: every user’s credential should be indistinguishable when “shown” to the resource. The obvious question is: why doesn’t the the issuer give a copy of the exact same exact credential to each user? In principle this solves all of the privacy problems, since every user’s “show” will literally be identical. (In fact, this is more or less the digital analog of the physical wristband approach.)
