Encrypted Spaces An architecture for collaborative applications

Encrypted Spaces is a research architecture that enables collaborative cloud applications while keeping data encrypted and unreadable to servers. The system uses cryptography and zero-knowledge proofs to allow servers to store and synchronize data without accessing plaintext information, addressing risks like data exposure, loss of user control, and self-censorship. Researchers are prototyping a sync engine similar to Firebase that implements encrypted spaces to demonstrate the practical viability of trustworthy collaboration tools on untrusted infrastructure.
