Could someone tell me why Ethereum is so important plz.

thx

We need another hard fork in the ass.  
 ...

I think ZCoin is very profitable now. 500% faster than the i7 on the 750ti with the sp-mod.

Sp you have pm , and is possible get more information ? .

Thanks .

old vertcoin = lyra2RE (lyra2 chained with some other algos)
new vertcoin = lyra2REv2 (lyra grid is smaller than previous, still chained with other algos)
zcoin = plain lyra2 (not chained with other algos) WITH variable grid size based on block height (A LOT  bigger than in the other two cases)

Corrrect.

The CPU implementation can saturate an I7's memory bandwidth with only 4 cores (maybe less) using only scalar instructions.
Vectorizing (4:1) had no effect on hash rate.

Any GPU miner would also hit a performance ceiling once memory bandwith was saturated. Given this occurs on a CPU
with only a couple of scalar threads I would expect similar on a GPU. In my opinion a viable GPU miner is out of the question.

But it's all moot now as zcoin will be switching to MTP and I doubt any other coin will choose this flavour of Lyra2.

High volume, large buy walls, it supports the crypto scene. Miners basically grow to the size of their tank, much like a goldfish. Ethereum is a very big tank. If Ethereum disappears, all those miners are going to have to be shoved into a bunch of very small fish bowls, which means not all of them are going to fit.

Essentially Ethereum supports the mining community and when it disappears miners are going to be very much hurting due to the amount of hashrate (other miners) on Ethereum. They aren't just going to give up and turn off their miners, they'll try to find other coins, whatever they can, to attempt to stay mining.

Ethereum armageddon is coming and that isn't just for show. Unless another coin becomes just as big as Ethereum there is going to be a lot of bad days for mining this spring.


As far as SP making a Zcoin miner... I don't think he knew when he wrote that that Zcoin doesn't use the normal version of Lyra2. There is no miner.

Considering the amount of volume going through zcoin right now, even if it's not a long term solution, if a developer could hack together something that works they'd get people to buy it. There is a lot of money right now being funneled into CPU botnets with that coin. It's not like this is a small volume coin. Even if it changes next week, that's an entire week worth of mining... and a lot of money.

That being said, they haven't even announced a schedule for when they're switching to the new algo so it probably wont be within the next couple weeks... Maybe even a month from now. If I were them I'd do it before Zcash launches as it appears to be a competing coin.

Thx Ben
Yes now I see what you mean....
I'm mining now below the cost of electricity.... .007 BTC a day .. use to be .065 BTC a day.
We got hit with asic's taking half the coins away.
Another country mining now.
Bitcoin halved .. alot dumped their coins.
New cards 1070's
In 2.5 yrs of mining ..I never seen it so bad.
Wow maybe it will stabilize again.

EVGA Pascal owners might want to take a look at this: https://www.reddit.com/r/buildapc/comments/58hnzb/word_of_warning_the_evga_1080_blackscreenfan_bug/

Hindenburg is going down folks. Zcash is still too far away.

Yup it hit the ground.

To much info given away on the threads.

So when is SP Lbry #4 coming out? XD

Figure I'd ask for shits and giggles.

Just as a FYI, I tried out one of the new Zotac 1070s (the one that looks like a crappier version of the AMP edition). They trimmed the bottom shroud on it as you can see in the pictures on Newegg. This DEFINITELY reduced the temperatures of the card as I predicted in my earlier post of the AMP edition cards. It cools as well as Asus and EVGA cards, but it's the cheapest on Newegg and looks like it will be Zotacs new 'bargain' card.

Would recommend it as a buy.

The fan profile seems a little bit more aggressive so it tries to keep the card cooler (which it does by default), but in the same setting running at 100% fan speed it cools it just as well as the other manufacturers I mentioned. I'd actually say it has one of the best coolers out of all the 1070s I've tried (I've tried all of them except for the three slot coolers).

It also has pretty beefy VRM heatsinks, which you can see under the shroud.

This guy. It's better then the AMP edition card except that it doesn't have two PCIE jacks so the TDP is lower. But given how shitty the cooler is on the AMP due to the shroud, that's a moot point.

Hi, "ccminer-1.7.6-r6-lyra2re" (LYRA2REv2)  It does not work with new drives nvidia 375.57 in Nvidia GTX 1070, exist solution?

[sambiohazard]

Shameless plug of referrals in my sig , if you are interested in cloud mining or renting rigs.

Never...

thats where you are wrong ...

when the new optimized code is released opensource - sp will copy that optimized code - 'optimize' it again - then charge everyone for the luxury of doing it ...

its how he works ... hence the large farm he now currently has - off the backs of everyone that bought private miners from him ... yes - including me ...

I'm more concerned with the fact that developers haven't released anything in the last couple months then paying for a miner again.


Since the word is already out and since no one is taking this shit up, might as well set fire to everything:

Boolberry - Needs a new backend and optimizations in addition to a working miner. Preferably something for solo mining as pool mining is a shit show
Cryptonite - Needs to have Pallas's binaries compiled into a working Windows miner
Zerocoin - Needs a temporary throw away GPU miner for use till they switch over to MTP (which is still a ways out). Something needs to be cobbled together, a lot of money there.
Riecoin - Needs a GPU miner. It's currently a CPU coin, but definitely looks like there could be a GPU miner and there are private GPU miners already operating on it.


Have at it. None of those coins in their current form are worth anything to me, perhaps if someone actually does a bit of work they can get it up and running for miners. I'm willing to pay for any of the above, as I'm sure other people are.

There is also Zcash on the horizon, but I'm pretty sure that's on everyones radar. All of those above coins have been stagnate for long enough.

[bensam1231]

Nicehash and other services are going to be supporting Zcash right out of the gates. My fears of Zcash becoming a flop may become a very real concern due to the shear amount of people that will be mining it at the beginning. I'd advise developers to look at the other coins I suggested in the interim and wait to see what sort of fallout happens from Zcash.

Ethereum is not to be trifled with and Zcash seems to be attracting miners from it.

I tried MONERO and I get 5.5h/s is that correct anybody?   what to mine says should be 150h/s.  thx

MISTAKE I MADE.....................why we don't have anything to mine.

Sp-mod private #1 does around  300h/s on the 750ti on windows 7. 500h/s on the gtx 970

[bensam1231]

*twiddles thumbs waiting for the Zcash launch*

*watches $60,000 worth of Zcoin volume getting funneled into botnets and AWS instances*

*whistles*


Still no idea why people implement CPU coins in this day and age. If it's not dominated by botnets, it's dominated by AWS instances.

750h/s with 1070, not my result, still need to try the last version with cuda 8, but there was someone reaching it
