How To Hallucinate A Server by gubsheep | Devcon SEA

Thu, Oct 2, 2025, 12:00 AM

A Hallucinated Server is a virtual server whose execution is cryptographically simulated by users, using "multiplayer" privacy technologies like multi-party computation or fully homomorphic encryption. Today, thanks to recent advancements in MPC and FHE, we have the technology to build the first fully Turing-complete hallucinated servers. We discuss the underlying technologies, and how we've used them to build several proof-of-concept applications.
