Getting Ready for the Zcash (ZEC) Official Launch Tomorrow

Zcash (ZEC) is a new crypto currency project that launches officially tomorrow on 28th of October and there is already huge user interest in it and a lot of hype. Since ZEC coins will be mined and the development of miners and pools is currently moving very fast thanks to the significant interest from users you might want to be ready and up to speed with what is happening. What a lot of people still may not be aware of is the fact that Zcash has implemented a slow-start mechanism for the first 20,000 blocks (or about 34 days), meaning that the block reward will start at 0 coins and gradually move to the 12.5 ZEC reward in the course of the first 20K blocks. It will take a bit more than 2 days for the block reward to reach 1 ZEC and before that with the expected huge amount of hashrate thrown at the network right from the start the initial rewards for miners will most likely be very small. The linear rate of block reward increase effectively creates half as many ZEC in the first 20,000 block period resulting in 125,000 ZEC mined instead of the normally expected 250,000 ZEC for the first month of mining.

Now, regarding mining, there are already a couple of mining pools available (mostly running on testnet) and a number of miners and more work is currently being done on improving miner performance and increasing compatibility. It seems that the NiceHash nheqminer is currently a popular choice, even though it currently supports only CPU mining and CUDA GPU mining with OpenCL support apparently expected shortly. The original miner from NiceHash is hardcoded to support only their mining pools, though since the source code is available other pools have adapter it to work with them as well (you need to get a dedicated version of the miner for that). Have in mind that mining Zcash on NiceHash might be more interesting option for some, but not for other users as you will be getting paid in BTC instead of ZEC… remember that you are essentially selling your mining hashrate and getting paid in BTC and not mining ZEC directly with them. There is also the alternative of purchasing Zcash Cloud Mining Hashrate from Genesis Mining

Here is a list of pools where you can mine Zcash (ZEC) when the mining starts tomorrow October 28th and get paid in ZEC coins, note that besides each pool there is a link for the miner that supports it. Do note that the list of pools is probably not complete, so if you find a missing one please post it in the comments, so that it can be added in the list. Make sure that the pool is already operational and running on the testnet and clearly states what miner is supported in order for people to be able to test it…

Thanks for the write-up!

Hoping you can help clear something up for me. I’m still confused regarding what the optimal mining rig would be. I currently have a 6GPU rig I built for mining Ethereum, would this be an efficient setup for ZEC?

Thanks again for the article!

you have to wait for start, maybe mining eth will be still more profitable… besides i saw benchmarks where cpu had the same hashes as gpu …. we should get table what cpu/gpu have mining power to decide

I’m a bit confused in how miner performance is being measured/captured here….Genesis advertises a speed in H/s, but Windows CPU/GPU miner seems to measure in both “I/s” and “Sols/s”. Is there some way to standardize these measurements?

Some benchmarks from me:
gtx980: 18.5 Sols/s
2x gtx750ti: 12.6318 I/s, 23.4121 Sols/s
17-5930k @ 4.5ghz (12 threads): 22.2304 I/s, 40.7416 Sols/s
Total: 42.6567 I/s, 80.19 Sols/s

Andrew, I suppose that you are using AMD RX 4×0 GPUs in that rig? It should be able to give you a good performance for mining Zcash, though it is still hard to say which GPU does better. GPU miners are still being optimized for the new algorithm being used by ZEC, so the initial performance we can currently get might not be the optimal one, but it will most likely improve. At the moment some high-end CPUs with some OC are able to provide higher hashrate than some video cards, but that will probably change…

Brandon, yes, it is really confusing for a lot of people. Generally H/s and Sols/s should be representing the same thing…

so zcash is constructed that only 90% going to miners when mining… so milions miner will work for their profit? I wonder if some pool can hack it to get that 10% for selfs, hey it is all shielded, noone will know where money flow….

5820k at 4.6GHz is making 30 Sols/s
Overclocked 1070 at 24.9 Sols/s

For comparrison

4790k at 4.6GHz making 32 Sols/s
overclocked 980gtx 22 Sols/s

my cpu take 112W and can do 40 sols/s when my graphic card take 270W and do only 17 sol/s , looks like for now only cpu is profitable

Hello Ricardo , please what is your CPU ?

My 4790k at 4.6GHz making 30 Sols/s, but with stock CPUs fan the cores temperature goes up extremely high: more then 100 °C (setting -e 2 -t 8)

New Zcash OpenCL GPU miner available from Genoil – https://github.com/Genoil/ZECMiner

so no working pools at the moment?

I’m getting 19.6 Sols/s with an AMD FX-8350 at 4.6GHz. The Genoil OpenCL miner does not work with my Radeon HD 7970, the display driver crashes as soon as I run it. I’m on the Crimson 16.10.3 drivers.

@admin , so what are that 8 versions of “start” in 0.3.2 release? Genoil should add version history file…

Genoil’s OpenCL miner seems to be quite problematic and many people are having trouble making it work, we are among those with issues. For OpenCL mining the solution at the moment is to go for the Coinsforall pool and use their miner… CUDA miners have more choices available, though Flypool does seem to be our choose for the moment.
