🌍 Why Istanbul?
Istanbul is where East meets West, and ideas become movements.
This September, it becomes the epicenter of Zero-Knowledge thinking during Builders Week Istanbul, a full week of events, hacking, and deep tech conversations across the city.
There is no better place to explore Zero-Knowledge technology with leading international developers than Cryptist. Bringing together the World's and Türkiye's most talented developers with global friends, Cryptist aims to make Istanbul a hub for zero-knowledge developers.
