“Two hands are better than one.” The same is true when plotting with Chia. You may already have your main PC plotting away and it might be at its limit. You then remember that you have an older PC or laptop that is not doing anything that you can use for plotting also. But how can you do this? Do you need to install the Chia client on that machine? What about the private keys?
Plotting on multiple machines is simple once you know how to do it. Firstly, you need to know how to interact with Chia via PowerShell if you’re on Windows. I covered this a bit in my post about using PowerShell to Plot. To get started, open a PowerShell window on the main PC that is doing the farming.
Next, enter the following command the change directories to the Chia directory:
Update the <username> field with your windows username and make sure app-1.0.5 is the correct version of the Chia Client. Once there, we will now enter the command to view the keys. A quick note about this first. This command will display all your keys, including some private keys. Do not show this to anyone. Do not do this while sharing your screen on a Zoom meeting. Someone can take over your account if they know these. Not so much the public keys, but the private keys must remain private. Proceed to enter the following command:
.\chia.exe keys show
Entering this command will show a bunch of keys. There are two keys that we need; The Farmer Public Key and the Pool Public Key. These keys need to be passed onto the second PC that will be plotting. Added note: If you lost your 24 word mnemonic key when you first setup Chia, you can display them now by executing the following command.
.\chia.exe keys show --show-mnemonic-seed
Again, show these to no one. Anyone can take control of your Chia account with these words.
Copy and paste your farmer and pool keys into a notepad. Do not try to hand type the keys, one mistake and its a world of pain. You won’t be able to farm the plots that are made. Always use copy/paste. To copy text from PowerShell just right-click inside the window and select “Mark”. Highlight the text you want to copy and then right-click again. In the notepad window, just paste the copied text. Save the notepad file onto a usb stick and move it to the second computer.
On the second computer, you will need to install the Chia Client. Once installed, the Client will open. Just close this window, do not generate new keys and do not recover keys from the mnemonic phrase. Next, you will need to plot using PowerShell. Open a new PowerShell window and change directories to the chia directory listed above. Once in this directory, enter the following command to generate a plot with the specific keys.
.\chia.exe plots create -k 32 -b 3389 -u 128 -r 2 -t E:\temp -d D:\plot -n 1 -f <insert farmer key> -p <insert pool key>
Two additional flags are used in the create command “-f” and “-p”. Be sure you copy the correct keys to the correct locations. Once entered, the plotter will begin generating plots. Once done, transfer your plots to the location that the farmer is looking at to farm plots. The farmer will pick these up and will begin farming them. Repeat the cycle for as long as you wish.
