The power of the ZK approach gives us many other tools to limit the power of credentials. For example, it’s relatively easy to add expiration dates to credentials, which will implicitly limit their useful lifespan — and hopefully reduce the probability that one gets stolen. To do this, we simply add a new field (e.g., Expiration_Time) that specifies a timestamp at which the credential should expire.
