I no longer want to short Monero. You can rest easier. What I found can be fixed (if it isn't already). I believe I found BCX's exploit, although it is possible I found one that is different than his. And I believe he is incorrect about it not being fixable. At first thought, I too also thought it was a "coin killer".

Note I haven't worked through one part of the math so it is still possible that I am incorrect about this being an exploit, but I think I got the key epiphany of the exploit which makes it is possible.

It is also possible that this was already thought of and mitigated. I haven't checked the source code to verify. This is all conceptual at this point.

I had a sudden epiphany while at dinner which is BCX's exploit, well at least I can find the i == s and from that it may be possible to factor 'x' the private key.

I am trying to think of a fix. So far I can not think of any fix. I think BCX is correct, this is a coin killer.

I will also be contacting BCX to see if he wants to buy it from me since he wrote publicly that someone offered in 100 BTC for this.

BCX, do you have any interest in buying this from me instead of me selling to James, smooth, or BrilliantRocket?

And right after sending that PM, we get this on the forum:
