Let me put this into perspective a bit for
my view on this..
Last year i spent a lot of months looking into it on Securecoin and Quark and i also was accused of making a cheating miner too.
Long story short, after all the vast amount of code experiments & recompiling the miner(s) and testing on pool(s) i thought i found something. *at first.
But it turned out that i didn't find any kind of an exploit but a possible slight advantage at best and that is..
A miner coded to mine for easier than normal shares combined with a pool setup in a non standard way to accept easier shares is all that can be done.
This requires the pool owner / coder to set this up or it don't work period .
*with the right kind of pool too.. the exploit would not help finding blocks but would be for getting more shares submitted over other miners..
so if any of you are claiming this happened i highly suggest avoiding the pool operator who is making these claims
because he's the one cheating you NOT the miners..
Let me pose this scenario.. say i started a pool and i set the difficulty far below normal and then i coded my own custom miners
so that they accept lower difficulty shares this would give users of my miner an advantage over regular miners mining on the proper difficulty.
I found this out by accident basically by stumbling on to a pool that was doing this before.
and i stand by what i said earlier 100% !
OBVIOUSLY if you created / modified a pool to cheat then the pool is going to get cheated
and THAT is
not what i am discussing.
Bottom line is i have never seen one real coder say it happens.. because it's not possible code wise period.
the only people saying this are NOT coders and sorry but you don't know what your talking about.
and if a pool owner says it true ? stay away from his pools
edit:It's worth mentioning i have been coding and cracking for almost 15 years too.
For example i regularly crack or keygen a bunch of apps and i have done so on many platforms from Motorola Modems to Linux to various MIPS to Windows etc.
I reverse engineered the aglo (SHA256+custom) and i coded a keygen for my Firewall and i re-keygen it every time the dev tries to break my keygen too.
Same with some other apps.. no matter what the devs do over the years it takes me a few minutes to re-crack their app's LOL
So i know reverse engineering and i have the experience and mind set of a cracker.. looking for exploits is my hobby
and.... i looked at the code a LOT on all these miners
and hey, maybe it is possible but i don't think there is a chance in hell anyone will come forward with a miner code sample..
because i personally think it's virtually impossible.
