Please, try to understand that we will opensource all the jobs and miners will be able to use these improvements elsewhere, so it is not only exclusive work for us, but for community too. We do not benefit so much as for example, if we had closed source miner that could be used only on NiceHash.
in that case, your bounties are rather small...
I would like to pay you 2 BTC to make an opensource quark miner that does 45MHASH on the 980ti. (50%) faster. This is not a JOKE. This is a real offer.
If nicehash is also paying 2BTC you get 4BTC.
is it even possible ? (I mean one can't increase the hashrate to infinity...)
Also I never looked much into quark because an other dev was already working on it (ie yourself...) and was working on other things as well.
Quark highly unlikely, except if you manage to throw out 1/3 of instructions.
But algorithm like X11 is seriously underpowered on CUDA and this is where we have our interests in.
It also depends which GPUs do benefit. A kernel (and settings) optimized for broad specter of Maxwell cards (not only 750 ti and 970, but also for 950, 960, 980, 980ti and titan) is of course worth more.
I think x11@4,5MHASH is possible on the 750ti(50%), but it is alot of work. Worth alot more than 2 BTC..
In sgminer everybody is mining with closed source binaries. Why don't you make another bounty without the opensource part. The binaries can be used everywhere anyway.. To beat the closed source binaries is difficult and alot of work.. Remember that wolf0 once had his 70% faster x11 sourcecode for sale for 50BTC. Everybody complained about the price, but today everybody is using his work because somebody stole it and published the binaries.
Dash and the other x11 algos have a Net hashrate of more than 200GHASH per day. Wolf0's binaries have generated millions of coins to the miners.
