OK, if you were in control of the hashing algorithm used by Bitcoin, which one would you use and why?
I would use one that was not the product of the nsa, for reasons already given.
Which one? Give a concrete answer.
Also, please describe in detail exactly what you mean by a "broken" secure hash algorithm? What, specifically, would be able to be done with the broken hash algorithm?
I other words, given that the NSA has some sort of "back door" into the hashing algorithm, what would they be able to do with this back door? In what way could they harm Bitcoin with it?
