Re: [ANNOUNCE] Tenebrix, a CPU-friendly, GPU-hostile cryptocurrency
ckolivas won't add features for this Well, who knows, who knows.
As for the actual scrypt - lol r=1, p=1, N=1024 so you are joking right?
Since the scrypt part was done by ArtForz, I believe it would be most welcome if you provided a more elaborate criticism and kindly informed him of your opinion, so as to prevent possible distortion of you communication and expedite formation of improvements
And like I said, even if current PoW turns out to be insufficiently good at discouraging GPU mining, it can always be updated.
The real issue is that I'd doubt anyone would bother to write a GPU version since there is no gain from the effort and there are few who are experienced at working with OpenCL ...
We shall see...but the point isn't that OpenCL version is impossible (that indeed would be a nontrivial feat), the point is that it would be not verily likely to achieve even measly improvements over CPU in same approximate price range (I haven't yet decided as to criteria of performance increase "over CPU" in GPU implementations I could use as reference for bounty establishment, and am open to suggestions
)Should such a miner happen, the author will get a bounty, and whomever submits a patch that drops GPUs down again will get a bounty (so one can submit both the optimized GPU miner and Tenebrix fix to keep such optimizations at bay)
A: Efforts shall be taken not only keep up, but peek ahead of the curve and ensure that tenebrix remains CPU friendly and GPU hostile, no matter what kind of GPUs future science will throw at us. Being FPGA and ASIC hostile is harder, given their flexibility, though frankly, if someone, at some point in time, will be willing to throw that kind of money and engineering skillz at mining Tenebix, that already makes Tenebrix a success 
You do realize the guy who helped you write the code is an authority on FPGA mining, right?
Exactimundo.
That's why implementation by ArtForz > other similar endeavors (unless proven otherwise)
It would be trivially easy for him to implement it on his FPGAs.
Like I said, fighting something as flexible as FPGAs and ASICS seems fairly absurd, and is not main subject of Tenebrix endeavor.
The main goal is to keep GPUs (both "vanilla" and "pro") out of the pool for good.
If FPGA gets harder too - neat, but no biggie. If an optimized FPGA appears, no biggie, we're primarily hunting them GPUs here.
And the only scenario under which I could see ASICs being deployed on this chain is "USA abandons dollar, embraces Tenebrix as legal tender" (and at that point all COTS hardware gets out of the pool, lol
)
