alt Hacker NewsIt's not about traffic identification at all, but rather a hashing algorithm that is deliberately resistant to parallelization and GPU/ASIC acceleration, which shrinks the gap in solving speed between the fastest systems (i.e. datacenter-class compute resources) and typical systems (e.g. the CPU in your smartphone or laptop).
Uh, is it resistant to parallelization across multiple sites? Because that's the situation for the scrapers. They're not trying to solve a single PoW challenge across many cores.
