I think that there are a number of reasons this would be beneficial but the main one would be a reduction in the huge amount of energy wasted in mining
explain the nature of this so-called "waste". I'm going to give you a head-start: you can't
I can. POS would require less energy therefore POW is wasting energy. Simple enough.
Sadly, you were incapable of a meaningful explanation, as I suspected. The problem is that POS cannot achieve the quality of security that POW can, so your comparison isn't meaningful. That's why this design is the successful one: it works, lol (and hence why POS failed as a technology)
I know you are talking to banks - or my answer would not be friendly anymore
But I like the point you think of, but I think the way is not the right (hard switch)
Bitcoin was the new idea - maybe we need something new again (within bitcoin)
So we would need a mix from POS and POW maybe.
Solving "puzzles" is ok - but why not solve a puzzle like Boinc is offering.
YEAH - I AM YETI @Home - and I help SETI@Home
So fill up the POW with sencefull things may help. It would be not a waste of power anymore.
Curecoin for example is for cancer research.
A pitty BOINC has no COIN - but its 100% science related and I think the oldest system in this public way I know (Seti @Home was my first software like this --- uhhm --- 20 years ago)
And now Seti is a small BOINC one
And there is always enough to calclulate - even all ASICs and GPU on the world could not solve all REAL puzzles of mankind.
You can rent supercomputer power at almost any big research facility for real big money. Why?
They dont need power over a day. They need it most time FAST for a SHORT TIME with MAX POWER. (emergency results, weather results, results of ill people and and and ...)
And big research companies, goverments and hospitals are buying those power.
ofc they are not using a normal pc or server for clustering - you could say they are like ASICs for the science people and always for special coding.
Not even one normal software you and I know are working on it - not yet
And an ASIC, well --- looks not like I could use it for anything else.
I had the luck to see such a big cluster from inside and it is amazing!
Not to compare with even a big normal datacenter. Racks, too - but anything else was a new fantastic world
I am invited to see it again in 2 years and I will go again. I have so many new questions

Under the line. Lets calculate something important and we all feel better with bitcoin. Having them in the own wallet and doing something good while using (and mining) them
