The main focus is prototyping new privacy preserving applications, exploring the design space of zk x identity and improving the client-side proving tech stack. It will features teams from zk-email, jubmoji, proof of passport and other applied zk projects. We are aiming to develop new applications using zk, particularily by verifying signatures already present in the wild in payment systems, internet infrastructure or by governments and institutions. We want to contribute to creating more reliable digital identities that preserve privacy, new ways of socializing in in-person events, and ways to verify payment signatures to disintermediate on/offramps. Those applications are aligned with Zuzalu's values and can serve Zuzalu's mission. They can also be integrated with tools like Zupass. The goal is to have ~20 people in Japan for a month starting ~May 1rst.
