Even if you could, there's no way to guarantee it's the same code that's actually pushing your packets around.

Even vp.net which says they use SGX to verify the code that is running on a box... yea you are verifying a box, somewhere, not necessarily the one forwarding your packets. And those packets can still be monitored/modified outside the system at some other part of the network anyways.

And even if you could verify all that, eBPF swoops in and lets you modify code at runtime with no evidence trails.
