Going back pretty far in the stack this weekend, and reading the first Multikey FHE paper.

Main problem statement is outsourced, private, storage and computation of weak clients that are sporadicly online. Can’t really use classic MPC protocols since they assume weak, non-interacting clients.

hey propose Multikey FHE. Server computes f on subset of clients S chosen “on the fly” that may be offline.

There is a lot more recent research that removes the assumption of hard problems over ideal latices and adds distributed decryption, but it's a fantastic paper to start going down the rabbit hole.
