Researchers just built a Bitcoin miner out of fly brain neurons.
1 watt per terahash. Ten times more efficient than the best silicon on the market.
It's also microscopic, biological, and nowhere near deployable at scale.
While the labs figure that out, 20,000+ S21 XP machines are hashing across nine sites in Iowa at 13.5 joules per terahash.
The fly brain is a great story.
But the S21 XP is what actually finds blocks today.
