Summary This week Anna and Nico chat with Lukas Helminger and Ais Connolly from TACEO. They discuss Lukas & Ais’ early work in cryptography and privacy preserving technologies, the founding of TACEO and their recent work on coSNARKs - or Collaborative SNARKs - that combine MPC and ZK. They explore how these coSNARKs are created, their coCircom language, the characteristics of these systems as well as how they can be applied in the real world.
