Estimated Performance of Different GPUs

it/s – iteration per second

To give you a rough figure on how iterations per second correlate to the NIM rewards, let’s see the real-world example for the RTX 3080 TI and RTX 4090 GPUs that I currently rent at Clore.ai (as of 13 June 2024).

Three Simple Steps to Start Mining

Step 1. Create Nimble Wallets

You will need at least one master wallet and one sub-wallet. The former is for getting the rewards, and the latter is required for mining. Technically, there’s no difference between the two wallets, and you can choose to use either as your master wallet.

To create the Nimble wallets, follow the below steps. If you plan to rent GPUs to mine, I strongly recommend creating the wallets on your local machine rather than the rented ones.

sudo apt-get remove golang-go && \
sudo rm -rf /usr/local/go

sudo apt update && \
sudo apt install golang && \
export GOPATH=$HOME/go && \
export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin && \
go version

rm -rf $(which go)

brew uninstall go

mkdir ~/go && \
export GOPATH=$HOME/go && \
export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin && \
go version

sudo apt-get remove golang-go && \
sudo rm -rf /usr/local/go

cd /usr/local && \
sudo wget https://go.dev/dl/go1.22.1.linux-amd64.tar.gz  && \
sudo tar -C /usr/local -xzf go1.22.1.linux-amd64.tar.gz && \
export PATH=$PATH:/usr/local/go/bin && \
go version

Install wallet CLI

sudo apt install git && \
mkdir $HOME/nimble && cd $HOME/nimble && \
git clone https://github.com/nimble-technology/wallet-public.git && \
cd wallet-public && \
make install

Confirm the executable exists.

which nimble-networkd

Depending on your Go path, you should see something like /usr/local/go/bin/nimble-networkd or /username/go/bin/nimble-networkd.

Generate a wallet

Replace nodepedia with your desired name, e.g., master, wallet1, miner1, etc., and execute the following command to generate your first wallet.

nimble-networkd keys add nodepedia

You will be prompted for a passphrase (password); enter the password of your choice and hit Enter. The passphrase is only needed to export the private key or see the seed phrase again on this machine.

Congrats. You created your first Nimble wallet.

Repeat the same procedure for your sub-wallets (up to 10), e.g., nimble-networkd keys add wallet2.

Step 2. Approve the Wallets

All miners need to apply to mine the token.

Head over to ⁠the Nimble Discord and begin the process in the #wallet-application channel. You need to provide your master and sub-wallet(s) and give details on how you plan to mine, e.g., your own setup or cloud GPUs.

In the Discord channel #start-here, you can see a great explanation of how to apply by our Community Manager @LiddleJimmy 🧀, so I won’t repeat the same.

I’ll emphasize on a few key points:

• A master wallet can be any of the wallets you generated in Step 1.
• The master wallet is for the rewards only. Do not use it for mining.
• You can apply with 10 sub-wallets initially and re-apply with more sub-wallets using the same master address.
• 1 sub-wallet = 1 GPU.

Once your application has been accepted, you will receive a DM from the bot stating whether it has been accepted or denied.

Step 3. Start Mining

You’re all set. It’s time to set up the machine and earn some NIM tokens! 🤑

If you plan to rent GPUs, you may want to check out the cheap GPU rental options and then proceed to Host Setup and Starting Mining. If you want to mine with your GPU, go directly to Host Setup and Starting Mining.
