### Prerequisites

Before you begin, ensure that you have the following:

1.  **A VPS or Dedicated Server**:

    *   **Recommended**:
        
        *   CPU: 8 cores
            
        *   RAM: 16 GB
            
        *   Storage: 500 GB NVMe SSD
            
2.  **Operating System**:
    
    *   Ubuntu 20.04 LTS or later.
        
3.  **Basic Knowledge of Linux Command Line**.
    
4.  **Nesa Wallet**:
    
    *   Ensure you have a Nesa wallet with some initial funds for staking.
        
5.  **SSH Access**:
    
    *   Secure and reliable SSH access to your server.
        

* * *

### Step 1: Update and Prepare Your Server

1.  **Update your system**:
    
        sudo apt update && sudo apt upgrade -y
        
    
2.  **Install essential packages**:
    
        sudo apt install build-essential curl wget git -y
        
    
3.  **Set up a firewall** (optional but recommended):
    
        sudo apt install ufw -y
        sudo ufw allow ssh
        sudo ufw allow 26656/tcp
        sudo ufw enable
        
    

* * *

### Step 2: Install Dependencies

1.  **Install Go** (version 1.20 or later):
    
        wget <https://golang.org/dl/go1.20.5.linux-amd64.tar.gz>
        sudo tar -C /usr/local -xzf go1.20.5.linux-amd64.tar.gz
        export PATH=$PATH:/usr/local/go/bin
        
    
2.  **Verify Go installation**:
    
        go version
        
    
3.  **Install other dependencies**:
    
        sudo apt install jq -y
        
    

* * *

### Step 3: Install Nesa Node

1.  **Clone the Nesa repository**:
    
        git clone <https://github.com/nesa-network/nesa.git>
        cd nesa
        
    
2.  **Build the Nesa binary**:
    
        make install
        
    
3.  **Verify installation**:
    

* * *

### Step 4: Configure the Node

1.  **Initialize the node**:
    
        nesa init <YourNodeName> --chain-id nesa-mainnet
        
    
2.  **Download the genesis file**:
    
        wget -O ~/.nesa/config/genesis.json <https://raw.githubusercontent.com/nesa-network/mainnet/master/genesis.json>
        
    
3.  **Configure persistent peers**:
    
        PEERS="node1@<ip>:26656,node2@<ip>:26656"
        sed -i.bak -e "s/^persistent_peers *=.*/persistent_peers = \\"$PEERS\\"/" ~/.nesa/config/config.toml
        
    
4.  **Set minimum gas prices**:
    
        sed -i.bak -e "s/^minimum-gas-prices *=.*/minimum-gas-prices = \\"0.025unesa\\"/" ~/.nesa/config/app.toml
        
    
5.  **Pruning options** (optional):
    
        sed -i.bak -e "s/^pruning *=.*/pruning = \\"custom\\"/" ~/.nesa/config/app.toml
        sed -i.bak -e "s/^pruning-keep-recent *=.*/pruning-keep-recent = \\"100\\"/" ~/.nesa/config/app.toml
        sed -i.bak -e "s/^pruning-interval *=.*/pruning-interval = \\"10\\"/" ~/.nesa/config/app.toml
        
    

* * *

### Step 5: Start the Node

1.  **Start the Nesa service**:
    
        nesa start
        
    
2.  **Check logs** to ensure everything is running smoothly:
    
        journalctl -u nesa -f
        
    

* * *

### Step 6: Create and Fund Your Validator

1.  **Create a new wallet** (if you don't have one):
    
        nesa keys add <wallet-name>
        
    
2.  **Fund your wallet** with the necessary amount of Nesa tokens.
    
3.  **Create the validator**:
    
        nesa tx staking create-validator \\
        --amount=1000000unesa \\
        --pubkey=$(nesa tendermint show-validator) \\
        --moniker="<YourNodeName>" \\
        --chain-id=nesa-mainnet \\
        --commission-rate="0.10" \\
        --commission-max-rate="0.20" \\
        --commission-max-change-rate="0.01" \\
        --min-self-delegation="1" \\
        --gas=auto \\
        --from=<wallet-name> \\
        --yes
        
    
4.  **Verify your validator status**:
    
        nesa query staking validator $(nesa tendermint show-validator)
        
    

* * *

### Step 7: Monitor and Maintain Your Validator

1.  **Set up alerts** for node downtime using tools like Prometheus or Grafana.
    
2.  **Regularly update** your node by pulling the latest changes from the Nesa repository.
    
3.  **Participate in governance** by voting on proposals.
