Zero knowledge proofs are unusable for age verification because they're impossible to revoke. One person can share their ID and everyone else can use it.

    If it's possible to revoke then by definition it's not zero knowledge. Revocation status is knowledge.

      Sorry, i wasn't clear. If you have digital ID, you can emit time-limited certificates.
