Proof of stake

I'd like to understand why an hybrid POW/POS model a la peercoin doesn't seems to be considered as a good solution for the blockchain mining.

Since a node has to run two kind of calculations 1/ searching blocks and 2/ executing contracts, the more difficult 1/ is, the lower 2/ will be. Mathematical calculations has been done by Aeron Buchanan in the attached document, and my previous assumption is based on the last graph.

By limiting the space of acceptable solutions, POS is a more energy efficient way to mine blocks and consecutively nodes will have more power to execute contracts.

Do I miss something?

Oops. I miss that sentence in the white paper:
> There will be opportunities to explore alternatives such as proof of stake, proof of burn and proof of excellence as well.
