Fullnode setup

Here's a step-by-step guide to setting up a full Bitcoin node (bitcoind) on Ubuntu:

✅ Prerequisites​

  • Operating System: Ubuntu 22.04+ (64-bit recommended)
  • Disk space: ≥ 1 T (preferably SSD)
  • RAM: At least 2 GB
  • Internet connection: No bandwidth limits; at least 50 GB/month
  • Open port: 8333 for inbound connections (optional but recommended)

🧩 Step 1: Install Dependencies​

Open your terminal and run:

sudo apt update

📥 Step 2: Download and Install bitcoind​

  1. Go to https://bitcoincore.org/en/download/

  2. Copy the link for the Linux x86_64 tar.gz file.

  3. Run:

wget https://bitcoincore.org/bin/bitcoin-core-26.0/bitcoin-26.0-x86_64-linux-gnu.tar.gz
tar -xvf bitcoin-26.0-x86_64-linux-gnu.tar.gz
sudo install -m 0755 -o root -g root -t /usr/local/bin bitcoin-26.0/bin/*

Option B: Compile from Source (Advanced)​

Let me know if you prefer this and I’ll give exact steps.

⚙️ Step 3: Configure Bitcoin Node​

Create a config directory and a basic config file:

mkdir ~/.bitcoin
nano ~/.bitcoin/bitcoin.conf

Add this to bitcoin.conf:

server=1
txindex=1
rpcuser=bitcoinrpc
rpcpassword=strongpassword
rpcallowip=127.0.0.1
zmqpubrawtx=tcp://127.0.0.1:28332
zmqpubrawblock=tcp://127.0.0.1:28333

You can add prune=550 to save space by not storing full history (if not a full archival node).

🚀 Step 4: Run bitcoind​

bitcoind -daemon

Check status:

bitcoin-cli getblockchaininfo

📦 Optional: Enable at Boot​

To enable bitcoind to start on boot, create a systemd service:

sudo nano /etc/systemd/system/bitcoind.service

Paste:

[Unit]
Description=Bitcoin daemon
After=network.target

[Service]
ExecStart=/usr/local/bin/bitcoind -daemon -conf=/home/youruser/.bitcoin/bitcoin.conf -pid=/run/bitcoind/bitcoind.pid
ExecStop=/usr/local/bin/bitcoin-cli stop
User=youruser
Group=youruser
Type=forking
PIDFile=/run/bitcoind/bitcoind.pid
Restart=on-failure
RuntimeDirectory=bitcoind

[Install]
WantedBy=multi-user.target

Enable:

sudo systemctl daemon-reexec
sudo systemctl enable bitcoind
sudo systemctl start bitcoind
