proof of labor – Lowering Power Consumption of Bitcoin’s PoW with paired mining rounds

I discovered the next whitepaper on an algorithm referred to as “Inexperienced-PoW” by the authors and i am fairly positive this might be a perfacet answer and likewise would get acceptance by the miners and the neighborhood.

You will discover the white paper right here:
https://arxiv.org/pdf/2007.04086.pdf

Key level of the paper right here as a quote:

“To be able to cut back the vitality consumption in PoW, Inexperienced-PoW considers
mining rounds in pairs and adjusts the election mechanism in the course of the
first mining spherical within the pair, to permit the election of a small
subset of miners that may completely mine within the second spherical.
Assuming the overall community hashing energy is equally distributed amongst
miners, a big vitality saving as much as 50% may thus be achieved”

What’s your opinion on this strategy, are there any issues with this?
