Vouch was an app that was very helpful at each Zuzalu for events at members houses and coworking spaces where paid security was not present, and curation of members and guests was self managed.

Vouching will become more important as Zuzalu expands, and seen complimentary to Zupass. A vouch is like a recommendation, both contextual and specific to each user, for new and exisiting members.

The vouching system was used repeatedly by the Blockravers and later added to the Vibes map in Istanbul, showing how a web of trust can be built from vouching, and a framework for future coordi-nations. Vouches are orthogonal but complimentary to the private zk based Zupass. A user-to-user vouch, violates anonymity provided by Semaphore based zk proofs.

We see Vouching as something that is very interesting to the Zuzalu community, and hope to touch more usecases for the visitors of future events.
