Run this command:
ssh username@your_server_ipReplace username and your_server_ip with your actual VPS login credentials. You’ll be prompted to enter the password to complete the login.
Example: ssh root@192.0.2.123
Section 2: Installing and Running the Node
1. Update Ubuntu OS
First, update your Ubuntu system to the latest packages:
sudo apt update && sudo apt upgrade -y
2. Install Required Applications
Install the necessary applications: screen, git, and make:
sudo apt install screen -y && \
sudo apt install make -y && \
sudo apt install git -y
3. Install Go
Download and install Go:
cd $HOME
ver="1.21.3"
wget "https://golang.org/dl/go$ver.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$ver.linux-amd64.tar.gz"
rm "go$ver.linux-amd64.tar.gz"
echo "export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin" >> $HOME/.bash_profile
source $HOME/.bash_profile
go version
4. Clone the CARV Source Code
Clone the CARV Verifier repository and build the source code:
git clone https://github.com/carv-protocol/verifier.git && cd verifier && make build
5. Navigate to the Bin Folder
Change into the bin folder where the keystone generator and files to start the CARV node application:
cd bin
6. Create a Screen Session
Create a screen session called CARV:
screen -S carv
7. Generate a random burner wallet
Go to chaintool.tech and generate a random wallet by clicking on create.
You can either copy the address, mnemonic and pri-key to a text editor or export the generated wallet by clicking on download.
8. Delegate Your Node
Go to the CARV Alphanet Explorer, connect your wallet, and delegate your node to the generated wallet address.
9. Start the Verifier Node
Start the verifier node using the following command:
./verifier -private-key <Your Private Key> -reward-address <Your Reward Address> -commission-rate <Your Commission Rate>Replace the placeholders with your specific details:
<Path to keystore file>: The file path generated during the keystore creation.<keystore password>: The password you used for the keystore.<Your Reward Address>: The wallet address for your commission rewards.<Your Commission Rate>: Your commission rate (0–100).
Important: remove the first 0x from your private key.
Example of how the command should look like:
./verifier -private-key 4190ae49dcb5ca5dd4eda9db6f4ab6d7b73ec790afb921c64bfba026895e9e69 -reward-address eb4d75edb0dca607c9bb0a1388f1f0461f0ba045 -commission-rate 5If you get the error: GaslessService failed – System is busy, just re-enter the command until it goes through.
10. Manage the Screen Session
To minimize the screen running your verifier node:
Ctrl + A, then DTo re-enter the screen session:
screen -r carv
Congratulations, you have successfully installed your CARV Verifier Node!
