Commercium aims to be the go to currency for business to business (B2B). They use a dual chain approach where users can switch between the two digital currencies of CMM and CMMX. CMM is their current coin that is an equihash algorithm coin and is more of the currency type system, while CMMX will be the more product part of their platform since it is based on Ethereum and will allow for smart contracts. It seems the only available coin at this time is CMM so we will be mining this coin in this article.

Now that we know the details about Commercium, let’s get to mining some CMM!

Some General Mining Tips

So before we start this tutorial, I have two tips for making the most out of your mining experience. First make sure you have the latest drivers for your GPU’s. Secondly, most mining software will get flagged as a virus from virus scanners. Because of this, if your mining on your normal everyday use or gaming computer that has an antivirus installed, you will want to exclude the mining software from the antivirus. What I like to do, is I make one folder and then put all of my mining software in sub folders. I then exclude the top level folder from the antivirus and that excludes all the mining software.

Mining Pools

The first thing we need is a mining pool. You can solo mine, but the payouts could take months depending on how powerful your mining rig is, and the mining pools usually charge a very small fee (1% or less). Using a pool will allow you to receive consistent payouts, multiple times per day. For Commercium, we can use https://commercium.miningspeed.com/ I have chosen this pool because Miningspeed is a community oriented mining pool, with low fees (0.8%) and lots of features. They also have a mining pool setup for most of the equihash coins. This list is available on their homepage at https://pool.miningspeed.com

As for their features, there a large sized pool, they have servers in US, EU and Asia, they charge 0.8% fees and they have an SSL connection available to use for mining.

One thing that is unique about this pool is that they even have a batch file you can download for specific mining software, that will walk you through step by step on setting up your miners. We will not be using this batch file in this tutorial.

Now that we have a pool, lets start mining!

CPU Mining

Their are only two options for mining Equihash using a CPU. One is Minergate, but I don’t prefer them because they take a large percentage of your profits because of the easy to use system they have. The only real miner is Nicehash’s nheqminer. You can download the precompiled binaries for Windows or Linux.

We will not focus on CPU mining since it is not profitable, compared to GPU mining.

GPU Mining – Nvidia

For GPU mining there are many programs for Nvidia, but the one I have found to be the best is EWBF’s CUDA miner. The miner does have a 2% Dev fee. The miner is compatible with Windows and Linux. You can find the official page and the download link at https://bitcointalk.org/index.php?topic=1707546.0

Once downloaded, it is really simple to use.

Just create a new batch file (or script file if using Linux) inside the folder where the miner is and paste this into the batch file

miner --server mining_pool --port port --user wallet_public_key.worker --pass x --pec

Replace “mining_pool” with the server you want (us.miningspeed.com, eu.miningspeed.com, asia.miningspeed.com) If you want to use an SSL port, you must prefix the server with “ssl://” (ssl://us.miningspeed.com, ssl://eu.miningspeed.com, ssl://asia.miningspeed.com)

Replace “port” with the port you want

Use 2071 if mining using a CPU

Use 2072 if mining using a GPU (one or two GPU’s, for example a gaming computer)

Use 2073 if mining using a GPU mining farm (multiple GPU’s like 3 or more per computer)

Use 2074 if you want to use SSL

Use 2075 if mining using nicehash (renting hashpower from https://www.nicehash.com)

Replace “wallet_public_key” with your wallet address.

“Worker” is optional. Use this if you have multiple mining computers. For example I could do CNc91jX4huZbzpz5S45KnJLMjnTmihMmt4.officecomputer for one computer and then CNc91jX4huZbzpz5S45KnJLMjnTmihMmt4.gamingcomputer for another computer.

This way you can keep track of them on the pools dashboard.

For example my setup is: miner.exe --server us.miningspeed.com --port 2072 --user CNc91jX4huZbzpz5S45KnJLMjnTmihMmt4.officecomputer --pass x --pec

Double click the batch file to run the miner, and you should see something like this

The red arrow indicates the GPU’s it has detected in your system.

The blue arrow indicates the temperature and speed for each GPU as well as the total speed.

The green arrow indicates the power usage for each GPU.

GPU Mining – AMD

For GPU mining there are many programs for AMD, but the one I have found to be the best is Claymore’s ZCash miner. The miner has a 2.5% Dev fee, or a 2% Dev fee when using a SSL connection. You can find the official page and the download link at https://bitcointalk.org/index.php?topic=1670733.0

If you need the Linux version get it at https://github.com/nanopool/ClaymoreZECMiner/releases

Once downloaded, it is really simple to use.

Just create a new batch file (or script file if using Linux) inside the folder where the miner is and paste this into the batch file

setx GPU_FORCE_64BIT_PTR 1 setx GPU_MAX_HEAP_SIZE 100 setx GPU_USE_SYNC_OBJECTS 1 setx GPU_MAX_ALLOC_PERCENT 100 setx GPU_SINGLE_ALLOC_PERCENT 100 ZecMiner64.exe -zpool mining_pool:port -zwal wallet_public_key.worker -zpsw x -allpools 1 -i 8 -asm 1

If using Linux, remove all of the setx commands.

Replace “mining_pool” with the server you want (us.miningspeed.com, eu.miningspeed.com, asia.miningspeed.com) If you want to use an SSL port, you must prefix the server with “ssl://” (ssl://us.miningspeed.com, ssl://eu.miningspeed.com, ssl://asia.miningspeed.com)

Replace “port” with the port you want

Use 2071 if mining using a CPU

Use 2072 if mining using a GPU (one or two GPU’s, for example a gaming computer)

Use 2073 if mining using a GPU mining farm (multiple GPU’s like 3 or more per computer)

Use 2074 if you want to use SSL

Use 2075 if mining using nicehash (renting hashpower from https://www.nicehash.com)

Replace “wallet_public_key” with your wallet address.

“Worker” is optional. Use this if you have multiple mining computers. For example I could do CNc91jX4huZbzpz5S45KnJLMjnTmihMmt4.officecomputer and then CNc91jX4huZbzpz5S45KnJLMjnTmihMmt4.gamingcomputer

This way you can keep track of them on the pools dashboard.

For example my setup is: ZecMiner64.exe -zpool ssl://us.miningspeed.com:2074 -zwal CNc91jX4huZbzpz5S45KnJLMjnTmihMmt4.officecomputer -zpsw x -allpools 1 -i 8 -asm 1

If you are running large GPU’s (1GB of memory or more per GPU, jump down to the last part under the problems section, even if the mining software appears to work)

Double click the batch file to run the miner, and you should see something like this

The first image shows that the miner should pickup all of the GPU’s in your system (The 3 Vega GPU’s in my example)

The red arrow indicates the GPU temperatures and fan speed.

The blue arrow indicates the GPU speed and total speed.

If there are problems, you can try a few things.

#1 Use -asm 0 or don’t use the asm flag instead of using -asm 1. Note for Vega cards you have to use -asm 1 otherwise you will get an error.

#2 Try not using the setx commands. For Vega cards I got an openCL error before I used these options.

#3 If you get a invalid pool error try adding or removing the -allpools flag.

#4 If your miner crashes after a while try to lower the intensity by using -i 6 instead of -i 8

#5 You may not have enough virtual memory. You may need 16GB of virtual memory (for Vega GPU’s you need more like 16GB per GPU) to change this go to Control Panel -> System and Security -> System and the click Advanced system settings on the left. From there, click settings under the advanced tab. Next click change, and then on the third screen, uncheck automatically manage, choose custom size, and type in the size (in MB) for both text boxes. Then press the set button, and then the ok button.

General Troubleshooting

One thing to monitor for is stale or rejected shares. If you see a lot of stale shares, you may want to try a server that is closer to you. If you see a lot of rejected shares, try to lower the intensity of the miner if available.

How much Commercium will I earn per day?

To figure this out, you would go to http://whattomine.com and use their calculator. The calculator does provide a rough estimate, so you may get paid a higher or lower amount than what the calculator actually says. In this case, the Commercium calculator is located at https://whattomine.com/coins/255-cmm-equihash The calculator does provide a rough estimate, so you may get paid a higher or lower amount than what the calculator actually says.

Most of the values are already correctly entered, and you only need to edit a few values.

Hash rate: Enter your total speed (in solutions per second) for all of your mining computers. This would be the “total speed” value in your mining software. Make sure to add up all of the computers your using for Commercium mining.

Power: Enter the total amount of power (in watts) that your mining rig is using. Some mining software, like the EWBF miner for Nvidia, will measure this for you. You can also measure total power consumption for your computer using special software, or a kilowatt meter. I prefer using a kilowatt meter, because I find it to be the most accurate. Make sure to add up all of the computers your using for Commercium mining.

Cost: Enter the cost per kilowatt hour that you pay to your electricity company. I was able to find this info in my monthly bill, as well as on their website.

Pool fee: Enter the pool fee + the miner software dev fee. For our example if your mining on Nvidia, you would enter 0.8 + 2 = 2.8 If your mining on AMD, you would enter 0.8 + 2.5 = 3.3 (or if using SSL 0.8 + 2 = 2.8)

Hardware cost: Enter in the total cost of all of your hardware.

Using my AMD Vega system for an example, I will show you how to read the data. In the above image there is really 3 things that I look for.

#1 Look at the Difficulty 24h and the Difficulty 7 days. We want these to be around the same, which they are. This tells us that the calculations we will look at in the second image below, will be accurate for days to come, as long as the price is not volatile.

#2 Look at the EX. volume 24h and the Market Cap. Generally, the bigger these are, the less volatile the price will be. We want the price to not be volatile so our calculations will be accurate for days to come. In this example, the market cap is small, so the price could change a little day to day.

#3 Look at the Create 1 BTC in and the Break even in. It is always interesting to see how long it will take your mining rig to create 1 BTC. The break even in, will show you a rough estimate of how long it would take to pay off your mining rig, by mining this particular coin. This is great to use before you build your mining rig, to see how long it will take until you will see profits.

In this image, we can quickly see how many coins and USD value we will make in certain time frames. You want to look at the Profit column, since this is the value after paying for your electricity usage. I usually just focus on the daily payout in USD. By just focusing on this number, you can run the calculator for a few different coins, and quickly see which coin is most profitable for your mining rig setup. Keep in mind you also want to weigh the daily payout with the market cap. A low market cap coin may be really profitable one day, and then could have half the payout tomorrow.

That’s it. You should now be mining Commercium! Make sure to type in your public key into the mining pool’s dashboard, to keep track of your statistics.
