You can do CPU verification of it in 32-bit...

Yes but it is a lot of work. The eth core heavily depends on some big 64-bit libs.

You don't add code, you just change wich buffer the keccak pass is working on. Same code, free keccak. More BTC. But your mininer would need to connect to two pools at the same time.

You'd still need storage to swap out the keccak state. If you do that in global ram, you're only adding more latency instead of hiding it. In shared RAM, it's so much that it starts to press on occupancy.

I still need to look at some other potential oppurtunity for optimizing ETH (AMD only), but don't have much time now.

You only need to store when you find a nonce that produce a valid keccak hash. The nonce is just a 32bit integer and can be stored in the stack. (level 1 cache).
The merged mining could be a good way to hide donation mining.

Neat way of dealing with the memory limitations of Eth. Kudos on that BTW. I'm guessing merged mining isn't really a option for the majority of algos as they more fully utilize GPUs? What about for other memory intensive algos, like Cryptonote?


In other news, does anyone in here have experience with making coins or know anyone who would be a good contact for that? I'm looking into making my own, but would need someone with knowledge of making coins (not just copy paste). The coin wouldn't have to be anything special and could probably just clone another popular coin, however the usage of it would be completely different as would the distribution (but once again nothing super special). Some backend code would have to be written to do a few special things I have in mind, but very easy stuff. I could probably do myself, but it has to tie into the coin which complicates things and I have a lot on my plate besides this.

I'm trying to be vague, wouldn't mind talking with someone on here if you're interested. I don't have a lot in the way of monetary value, so it would probably be payment in the form of the currency we're making (which is monopoly money till things get going). Time frame would definitely be generous, but within reason. There may be a v2/3 of the coin as well depending on how the first generation goes. This has been something I've been planning for well over a year and isn't going to be a ordinary pump/dump coin.

If you guys have a referral, I'd take that too.

Here is some of the popular algos and their speed measurements with the 20 latest sp-mod releases on the 750ti. (EVGA GTX 750 Ti standard clocks)

http://cryptomining-blog.com/6289-evga-gtx-750-ti-with-different-versions-of-ccminer-spmod/





July 2015-november 2015

x11: +2%
quark: +6.2%
neo:    +8.3%
lyra2v2: +5.3%

But as you can see, the release 74 might not be the fastest in all algos.

x11(release 74) (+2%)
quark (release 70) (+6.73)%
neo (release 70) (+8.93)%
lyra2v2(release 67)(+6.7%)

Ethash nonce is 64-bit but that's still small. But on second thought you may be right, I was looking at the wrong end. If you simply do a couple of rounds of keccak after ethash already has completed, it could work! I'd say go for it :-)

Thinking about it a bit more, the easiest way forward would be to extend ethminer with a stratum proxy that ccminer would connect to. Ethminer would take care of DAG creation, CPU verification and work supply. It would be very low on resources.

Looks like a fine idea to me :-)

If I am thinking correct then that would be Dwarf Pool as the only pool with a stratum. I could be wrong also if that is not what you meant.

sp_, it is really nice to see the progress / improvements here, I can see you haven´t stopped developing the ccminer algos, my only regret is to do not participate anymore in this journey testing the miners and contributing with donations, I really wish sucess to you all, keep up the good work.


Cheers

If the profit continues dropping like this, we may all have to stop mining/developing :-(

That is a pitty, I have stopped mining here cause of government taxes (Electricity bill).

No it would be like this:
Ccminer <-> stratum <-> ethminer <-> ETH::getWork <-> any pool or ETH node

Yup it's getting there... A lot of volume is being dumped into BTC as it continues to climb. Altcoins may be left at the wayside in lieu of the mothercoin. Hopefully not, but we'll see.

Bump for this

I can't help but feel that when the price of BTC will increase next year mostly becasue of the halving, it should inevitably create interest in the crypto scene which should revive altcoins as well. Hopefully at least.

@bensam1231 you might want to contact @jyap on BCT or twitter. he is dev of JBS coin & very knowledgeable person. He might not develop your coin but he sure can help with little bits & advice if he has time. You can also join JBS slack here http://slack.getjumbucks.com/. Its a nice place to hangout & its open to all, just ask for an invite. I hope this helps

Regards
