đ Original message:This is silly, but I'll add my take:
This would create the incentive to have chips that are idle 50% of the
time and work harder 50% of the time. This means miners would buy twice
the chips to use the same amount of power, for example.
This in turn means a greater portion of your operational costs are spent
on chips, and a smaller portion on electricity, reducing the incentive
to use cheaper power and turn off when it's expensive, because you need
to recoup your investment. That seems like a bad thing.
Here's my proposal: if you want a PoW algorithm that's better for the
environment, make one where the chips are easier to manufacture, so
power costs become a greater portion of miner expenditures. Maybe
SIMON/SPECK would do it. It could also incentivize someone to find that
NSA backdoor...
