GPU Solo Miners (AMD):

• Windows x64 Solo Miner

GPU Solo Miners (Nvidia):

• SK-Miner Windows
• SK-Miner GitHub

GPU Pool Miners:

• Links to pool miners should be available on the pool website. Different pools may use different miners.

If you plan to solo mine Nexus, you will mine directly to your Nexus wallet. Before you can do so, you must add a small configuration change to the wallet itself.

First, close your Nexus wallet.

Navigate to %appdata%Nexus (~/Library/Application Support/Nexus on macOS) and open the nexus.conf file. Depending on your wallet, you may or may not have this file. If not, please create a new text file and save it as nexus.conf

You will need to add the following lines to the nexus.conf file before restarting your wallet:

• llpallowip=127.0.0.1:9325
• mining=1

This guide covers the basic steps to set up a Hash Channel miner. Each miner is different, though, so refer to that miner’s documentation (readme file, GitHub page, or similar) for detail.

Step 1 – Extract the archive file to a folder.

Step 2 – Open the the mining configuration file (miner.conf). For some miners, such as skminer, this is found in /resources/config. Edit the connection settings.

For solo mining:

• "url": 127.0.0.1:9325 (mines to your Nexus wallet, which must be running)
• "user": "x"
• "password": "x"

For pool mining:

• "url": pool hostname or IP address and port, provided by pool
• "user": NXS address you are mining to (typically in your Nexus wallet, pool may or may not allow exchange address)
• "password": only if pool requires, otherwise use "x"

Other settings can be adjusted or tuned per the miner documentation. Tuning a miner for GPU mining is as much an art as a science, and settings will vary based on your hardware setup. They can even vary from one graphics card to another, even if they are exactly the same brand and model.

Step 3 – Run the miner. Most miners include a .bat or similar file for this purpose.

Nexus does not officially support pool mining on the Hashing channel. Hashing pools are developed and operated by third parties. Any questions or issues with a pool should be directed to the pool operators.

To mine Nexus on the Prime channel, it is highly recommended that you use a mining pool to improve results.

Prime Solo Miners:

• Source Code [GitHub]
• Windows Binary x86
• Windows Binary x64

Prime Pool Miners:

• Official Nexus Prime miner: Source Code [GitHub]
• Third party tuned Prime miner (faster): Releases [GitHub]

For Prime channel mining, it is recommended that you use a mining pool. If, however, you prefer to solo mine Nexus, you will mine directly to your Nexus wallet. Before you can do so, you must add a small configuration change to the wallet itself.

First, close your Nexus wallet.

Navigate to %appdata%Nexus (~/Library/Application Support/Nexus on macOS) and open the nexus.conf file. Depending on your wallet, you may or may not have this file. If not, please create a new text file and save it as nexus.conf

You will need to add the following lines to the nexus.conf file before restarting your wallet:

• llpallowip=127.0.0.1:9325
• mining=1

This guide covers the basic steps to get the Prime miner up and running.

Step 1 – Extract the archive file to a folder.

Step 2 – Open the miner.conf file. Edit the following items:

• "host": pool hostname or IP address, for solo this should be an address in your NXS wallet
• "port": use “9549” for pool, “9325” for solo
• "nxs_address": NXS address for pool payout, empty ("") for solo mode

It is also recommended to add this item to the .conf file, if not already present:

• "experimental" : "true"

This option enables the miner to use an improved sieve algorithm which will enable your miner to find primes at a faster rate.

Step 3 – Run the nexus_cpuminer. On Windows builds, you should run the start.bat file, which will automatically restart the miner if it shuts down for some reason.

Step 4 – Tune the miner.

There are two additional items in the miner.conf that you can adjust to tune your miner:

• "sieve_threads": number of CPU threads to use for sieving
• "ptest_threads": number of CPU threads to use for primality testing

If you have a more powerful CPU with more cores, it can run faster (higher WPS – the Prime mining equivalent to hash rate) with higher settings for these values. As a rule of thumb, the number of threads used for the sieve should be around 75% of the threads used for testing. It will likely require trying different settings for these to determine what gives the best results.

You can leave most of the remaining items in the miner.conf file set to their default values.
