A Full Node is a crucial component of the network, responsible for verifying transactions and blocks independently. Unlike simplified wallets that rely on external sources, a Full Node maintains a complete copy of the blockchain, ensuring that every transaction follows the protocol’s rules.

Full Nodes play a vital role in maintaining decentralization by communicating with other nodes, validating data and propagating verified transactions and blocks throughout the network. This distributed process enhances security and prevents unauthorized modifications to the ledger.

In addition to securing the blockchain, Full Nodes provide support for lightweight wallets, allowing transactions to be sent and updating balances without relying on centralized services. A strong network of Full Nodes ensures seamless and unrestricted access to PortusCoin.

Running a Full Node requires computational resources and a stable internet connection, but it offers significant benefits, including increased privacy, enhanced security and the ability to contribute to the long-term stability of the network. By setting up a Full Node, you are actively participating in the evolution of PortusCoin, helping it remain accessible and decentralized for everyone.

📌 Prerequisites

Before starting, make sure your system meets the minimum requirements.

📌 Step 1: Update Your System

To ensure compatibility, update your system packages before installing dependencies:

📌 Step 2: Install Dependencies

Install the required libraries and tools:

sudo apt install -y \
    build-essential \
    libtool \
    autotools-dev \
    automake \
    pkg-config \
    bsdmainutils \
    curl \
    git \
    python3 \
    python3-pip \
    libssl-dev \
    libevent-dev \
    libboost-all-dev \
    software-properties-common

📌 Step 3: Install Additional Libraries

These libraries are needed for network communication, database management and graphical wallet support (optional):

sudo apt install -y libzmq3-dev libminiupnpc-dev \
    libqt5gui5 libqt5core5a libqt5dbus5 \
    qttools5-dev qttools5-dev-tools \
    libprotobuf-dev protobuf-compiler \
    libqrencode-dev libfmt-dev

📌 Step 4: Install GCC 7

Ensure you have the correct compiler version installed:

sudo apt install -y gcc-7 g++-7
sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 50
sudo update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-7 50

📌 Step 5: Install Berkeley DB 4.8

Berkeley DB 4.8 is required for wallet functionality:

mkdir -p ~/berkeleydb
cd ~/berkeleydb
curl -LO https://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz
tar -xvf db-4.8.30.NC.tar.gz
cd db-4.8.30.NC/build_unix
../dist/configure --prefix=/usr/local --enable-cxx
make -j$(nproc)
sudo make install
cd ~
sudo ln -s /usr/local/lib/libdb_cxx-4.8.so /usr/lib/libdb_cxx-4.8.so

📌 Step 6: Clone and Compile PortusCoin

Download PortusCoin source code and compile it:

git clone https://github.com/PortusCoin/portuscoin.git
cd portuscoin
make clean
./autogen.sh
./configure
make -j$(nproc)
sudo make install

📌 Step 7: Configure Firewall (UFW) and Open Required Ports

Ensure your node can communicate properly with the network. Enable UFW (Uncomplicated Firewall) and open the necessary ports:

# Allow SSH (Port 22) to maintain remote access
sudo ufw allow 22/tcp

# Allow PortusCoin Mainnet Port (11333)
sudo ufw allow 11333/tcp

# Allow PortusCoin Testnet Port (21333) if running a testnet node
sudo ufw allow 21333/tcp

# Verify firewall rules
sudo ufw status

# Enable UFW
sudo ufw enable

This ensures your node can connect to other nodes, send and receive transactions and stay properly synchronized.

📌 Step 8: Start the Full Node

Once installed, start the PortusCoin daemon:

portuscoind -daemon

📌 Step 9: Verify Your Node

Check if your node is running correctly with:

portuscoin-cli getblockchaininfo

📌 Need Help?

Visit the PortusCoin Support page or join the community on Discord.

If your node is not syncing, ensure that:
✅ Your internet connection is stable.
✅ Your firewall settings allow PortusCoin traffic.
✅ Your node software is up to date.
Try restarting your node to resolve any temporary glitches.
