My limited understanding of MPC is that it makes a node’s data private from another node. Doesn’t that somewhat conflict with blockchain, whose entire purpose is to perform the same computation on multiple nodes? How would consensus be reached when each node is processing only one part of the input?
Also, I wonder if the AMD SEV initiative is still ongoing, or has hardware-enforced privacy like SEV been deprioritized in favor of software-enforced privacy like MPC?
EDIT: Just noticed there is also this long-term proposal.
