The Usefulness Gap in Proof-of-Useful-Work: An Empirical Study of Pearl's cuPOW Protocol

Summary

Researchers measured Pearl's AI mining protocol and found that its 320,000 GPU network produces zero useful AI computation, despite consuming 112 MW of power.

Why it matters

The study highlights a gap between the claimed benefits of Proof-of-Useful-Work (PoUW) protocols and their actual performance.
