One cartoonish (but helpful) way to start is to picture an advanced AI looking at all this bitcoin compute (all this massive processing thrown at factoring random numbers) and pulling it's hair out and screaming JUST GIVE IT ALL TO ME. As bitcoin miners switch from ASICs to GPUs to earn instead from model compute, what they are doing in a way is listening to this JUST GIVE IT TO ME scream. Eventually most of the bigger miners will move their farms to GPUs, even though it's a total refit, because why mine bitcoin at scale and earn x when you can provide model compute at scale and earn x + 1. Left mining Bitcoin will be smaller firms for whom the revised difficulty adjustment still makes it worth it, and home miners, etc. So Bitcoin will still be okay but it won't be the currency of choice for agents. How agents trade in model compute is simply bartering an agreed amount of future model compute of x standard as per y guarantee. The protocols that govern x standard and y guarantee will be the protocols that matter.
