How can we make this work long term?

I do not understand how this can be stable since you are relying on donating memory and compute?

I would love to use this concept in production over AWS but I do not see how this will work long term unless you have some way of bartering.

For example, if I have a 10x more "powerful" computer (cpu/gpu/tpu etc) then you have to give 10 computes for every 1 of my computes.

This way the system is balanced otherwise you are relying on philanthropy which is not stable.

Is there any way to incorporate a memory/compute based economy?
