In a way, you can look at this as incentivizing the progression of technology (creating more efficient hardware for the solving of more complex mathematical problems, synonymous with technological progression). Kinda cool to think about!
With that in mind, I can see POW staying viable for a large chunk of time, but I still believe that DPOS chains will be the technology that really takes hold and makes the most prospective use cases a reality.
Flagged. Eat shit.
