I've already reached out to him on other threads and via PM. So far he hasn't been even remotely clear on what he has or how much he's willing to sell it for, so there's no way for us to know if it's something worth crowdfunding.
He claims no one in the XMR community is interested in what he has, but he needs to meet us somewhere in the middle. I personally think he has no interest in ever selling his information, which is why he's so reluctant to name a price.
Nicely put. In any case, I believe this time it's his turn. Either he wants to reveal what he has (ie: describe in detail what he has managed to solve / created) or we assume he has nothing at all. Simple as that. In any case if he has something usable and worthy from the XMR devteam, I repeat what I wrote in his "ion" thread; I'm willing to donate some of my XMR stash in order to buy his work if he's for real.
Let's see what he decides.
Since I'm new to all of this, what has this guy said to have created that's better than the current ring sig/CT thing we are working on already? Does he claim to have some better way to implement this stuff or something of the sort?
