Masternode Guide

Step-by-step instructions to help you set up and run a Selenium masternode

Prerequisites

Before you begin, ensure you have the following:

1. Collateral: A minimum of 2,000 SE (depending on the reward phase).

2. VPS or Dedicated Server:

   • CPU: Minimum 1x 1GHz (Recommended: 2x 2GHz)

   • RAM: Minimum 1GB (Recommended: 2GB)

   • Disk Space: Minimum 8GB (Recommended: 16GB)

3. Selenium Wallet:

   • Download the wallet from Selenium Wallet.

Step 1: Prepare Your VPS

1. Rent a VPS

• Rent a VPS from a provider like DigitalOcean, Vultr, or Linode.

• Recommended OS: Ubuntu 20.04 or 22.04.

2. Access Your VPS

• Connect to your VPS via SSH:

  root@<your_vps_ip>

  Replace <your_vps_ip> with your server's public IP address.

3. Update the Server

• Run these commands to update your server:

  sudo apt update && sudo apt upgrade -y

4. Install Dependencies

• Install the necessary tools:

  sudo apt install -y curl wget unzip ufw

Step 2: Set Up Your Wallet

1. Generate Collateral Address

• Open your wallet and navigate to Tools > Debug Console.

• Run the following command to generate a new address:

  getnewaddress

• Send the required collateral (1500 SE) to this address.

2. Create a Fee Address

• Generate a separate address for transaction fees:

  getnewaddress

• Send a small amount (1 SE) to this address.

3. Create Addresses for: Owner, Voting, Rewards

• Generate 3 separate addresses for each:

  getnewaddress

• Save these 3 addresses.

---

Step 3: Generate Masternode Outputs

1. Wait for Confirmations

• Ensure your collateral transaction has at least 4 confirmations.

2. Get the Outputs

• Run the following command in the debug console:

  masternode outputs

• Example output:

  {
    "618599438df959fc0647ad1895808ba0fef96282bf24eb177134cb0c329c8d41": "1"
  }

• Note the Transaction ID and Output Index.

Step 4: Generate a BLS Key Pair

Run the following command in the debug console to generate a BLS key pair:

bls generate

Example Output:

{
  "secret": "5120ef8b654b7b7a459e19cc3ef3f845ba891404853fa317f348635b347e12ef",
  "public": "098254992464a87643d228e69554fda8f5feb52e9605b9cef2fe73eb3a063f12c8f03a6fa4f07e26a1e9e9875e1c5c91"
}

• Save the public key and private key for later use.

---

Step 5: Register Your Masternode

Prepare the ProRegTx

Use the following command to prepare your ProRegTx transaction:

protx register_prepare <Transaction ID> <Output Index> <VPS IP:Port> <Owner Address> <Public BLS Key> <Voting Address> <0> <Reward Address> <Fee Address>

Example output:

9c76272b7ef2a7456c84158424eb138bd3636b09aa2beae973bbed921f1f7868

Step 6: Configure the VPS

1. Download and Install Daemon

• Download the Selenium daemon from GitHub:

  wget https://github.com/seleniumofficial/Selenium/releases/download/v1.0.0/selenium-1.0.0-Ubuntu-Daemon.tar.gz

• Extract and install:

  tar -xzvf selenium-1.0.0-Ubuntu-Daemon.tar.gz
  sudo mv seleniumd selenium-cli /usr/local/bin

2. Create a Data Directory

• Create a directory for the masternode data:

  mkdir $HOME/.selenium

3. Configure the Masternode

• Create the selenium.conf file:

  nano $HOME/.selenium/selenium.conf

• Add the following details:

  rpcbind=127.0.0.1
  rpcallowip=127.0.0.1
  listen=1
  server=1
  daemon=1
  maxconnections=125
  masternode=1
  masternodeblsprivkey=<BLS Secret Key>
  externalip=<Your VPS IP>

Save the file and exit (Ctrl + X, then Y).

4. Start the Masternode

Run the daemon:

./seleniumd

Verify the status:

./selenium-cli masternode status
