Stalwartbucks Pool Mining

It has already become difficult to solo mine SBX using a CPU. We have set up an experimental pool. Hopefully someone with more experience running pools will create alternative pools.

Set up an account and click on the verification email. Then go to “Add Workers” and create a worker. If your username is foo, a worker name could be bar1.

The URL for connecting to the miner is stratum+tcp:// If you use the popular cpuminer, you would invoke it like this:

./minerd --algo scrypt --url stratum+tcp:// --userpass foo.bar1:password

(All in one line.)

Pool mining with MacMiner

MacMiner is graphical interface for a couple of cryptocurrency mining tools, including the fast cpuminer. It works both with Bitcoin and with Litecoin, which uses the same crypto algorithms as Stalwartbucks. Unfortunately it’s very insistent that you mine with their Bitcoin or Litecoin tools. Here’s a way to set it up to mine Stalwartbucks in a pool:

  1. Set up an account on the pool. Remember to verify your email address. Check in the spam folder if you can’t find the verification email.
  2. Go to “My Workers” and add a worker:


    Your mining username will be username.workername. Your mining password is separate from the password used for logging into the pool website.

  3. Download MacMiner.
  4. Launch MacMiner, then click “Show CPUMiner” in the View menu.


  5. Click on the gear button.


  6. You will see the CPU Miner Options window. At the top left, enter the number of threads you want to mine with. It’s probably a good idea to limit it to 1 or 2 threads to avoid heat damage and excessive fan noise. In the “Manual flags:” field, enter this:
    --url stratum+tcp://
    This is what it would look like:


  7. Now click “Edit pool settings”. Delete the contents of every text field, and enter the information shown below. Replace username with your mining username (actual username dot worker name) and put in the worker password you selected earlier (not the password you use to log on to the pool site!).


    Click “Save & start”.
  8. You’ll get this message saying that MacMiner has nonetheless selected its default pool. This is probably not true, but we will double check in a second.


  9. We’ve now started mining. As you can see, it selected the correct pool.


If you quit and relaunch MacMiner in the future, remember to select CPU Miner again from the View menu.

Command line CPU mining on a Mac

If you download cpuminer and extract the Zip file (your browser may do this automatically), you will find a file called minerd in your Downloads folder.

Launch a Terminal (in Applications → Utilities) and type in the following:

cd ~/Downloads
chmod +x ./minerd
./minerd --algo scrypt --url stratum+tcp:// --userpass foo.bar1:guanrocks

Replace the parts in red. If you only want to mine using one thread, you could add --threads=1.

Here’s how it might look:
