About

Zupass is a zero-knowledge identity and ticketing system first developed for the Zuzalu 2023 popup city. It allows users to prove membership in a community or attendance at an event without revealing their personal identity, using ZK-SNARK cryptography.

Originally built as a practical tool for Zuzalu, Zupass has since been adopted by multiple events and communities as a privacy-preserving credentialing system and is maintained as an open-source public good by the 0xPARC Foundation.
