What is your guess about this vaporware below? Don't worry you won't offend me, just be frank.
Does such a credible and correct unpublished white paper exist? Yes or no?
How the hell do I know? Correct would be especially hard to say if it is unpublished, since that would limit who might be scrutinizing it for errors or unstated (here at least) assumptions.
Here is a quadruple dose of FUD...
Wouldn't it be ideal if a coin's whitepaper has a mathematical proof that it isn't vulnerable to anything less than a 50% attack (other than the normal 6 confirmations type risk of double-spend)?
And wouldn't it be porn, if that proof showed that every other proof-of-work coin (including Bitcoin) is so vulnerable?
And wouldn't it triple sexy if that proof showed that all (untraceable block chain) anonymous coins can't be fixed to remove that vulnerability?
Excuse my drooling, I can't contain myself.
Edit: I have not withheld any quantification of TW attack on CN afaik. I shared all of my (limited) knowledge on that. I am referring to something different above.
