ZK in Cosmos (formerly Privacy in Cosmos) is an event series hosted by ZKV. 

In the last three years, we have hosted five events, two of them IRL, to showcase the privacy use cases built in the Cosmos ecosystem. 

The first four events were funded by the Cosmos Hub. Since last year with Privacy in Cosmos Live in Prague, we have been self-funding the event to give back to the community.
