Common Ground

Proof of liveness (ZK client side) - Aka Proof of human

IDs and image vectors. Proof of liveness that works directly on the user's device and is able to generate a liveness proof (verifiable on-chain) without specialized hardware, or need to share biometrics to external servers. Client side ZK-image recognition is required by Rarimo.

private event planning

You should be able to sign up for events as easily as with luma, but you shouldn't get spammed by random projects because you shared your email or other information after. Using the zupass API to create a luma experience that is fully private! Private state: user information

zk visitorID database

Private and encrypted database verification system for building access that requires ID for security purposes
