Maybe I didn't mean blockchain, cause I'm still not really certain what it is. I mean like the fediverse itself, or a mesh network, where a bunch of hobbyist self-hosting their own servers can federate as a system of nodes for a more distributed model.

Instead of all the compute being hoarded in power-hungry data centers; regular folks, hobbyists, researchers, indie devs, etc., would be able to run more powerful simulations, meta-analyses, renderings, etc., and then pool their data/collaborate on projects, and ultimately create a more efficient and intelligently guided use of the compute instead of simply "CEO says generate more profit! 24/7 overdrive!!!"

At the very least, a surplus of cheap RAM would expand the computing capabilities of everyone who isn't a greedy corporation with enough money to buy up all the expensive RAM.
