Connecting more phones is one thing. Giving them something useful to do is another.

That's the part of Acurast I find worth watching.

Turning idle smartphones into decentralized compute sounds promising, but onboarding devices is only half the challenge. Developers still need a reason to pay for that computing power.

What I like about Acurast's design is how it connects network activity to $ACU . Execution fees are burned, while processors completing tasks can receive additional reward bonuses. So actual compute usage plays a role in the token economics, not just the number of devices joining.

Of course, none of this guarantees demand. And that's probably the biggest challenge for DePIN projects in general.

I'd rather see 100,000 phones doing useful work than a million sitting idle.

Because in the end, it's not about how much compute a network has. It's about how much of it people actually need.
