How to Set Up a Bitcoin Full Node (Pruned) on Ubuntu


Step 1: Get Your Server Ready

Before we begin, make sure you have:

  • A Linux server running Ubuntu (VPS or baremetal)

  • SSH access to the server (you should be able to connect via terminal)

  • At least 2GB of RAM and 50GB of storage (depending on your needs)

  • A stable internet connection


Step 2: Update Your Server

Log into your server and update the package lists:

 sudo apt update && sudo apt upgrade -y 

Step 3: Install Bitcoin Core Dependencies

Install required libraries for Bitcoin Core:

sudo apt install -y build-essential libtool autotools-dev automake pkg-config bsdmainutils python3
sudo apt install -y libssl-dev libevent-dev libboost-system-dev libboost-filesystem-dev libboost-chrono-dev libboost-test-dev
sudo apt install -y libzmq3-dev libminiupnpc-dev libsodium-dev
sudo apt install -y libdb-dev libdb++-dev libnatpmp-dev
sudo apt install -y libssl-dev libevent-dev

Step 4: Download Bitcoin Core

Next, we’ll download Bitcoin Core from the official website:

wget https://bitcoin.org/bin/bitcoin-core-24.0/bitcoin-24.0-x86_64-linux-gnu.tar.gz
tar -xvf bitcoin-24.0-x86_64-linux-gnu.tar.gz
cd bitcoin-24.0

Step 5: Install Bitcoin Core

Now install Bitcoin Core:

sudo cp -r bitcoin-24.0/bin/* /usr/local/bin/
    

Step 6: Configure Bitcoin Core (Pruned Mode)

Create a Bitcoin configuration file to enable pruned mode.

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

Paste the following configuration into the bitcoin.conf file:

# Bitcoin Core configuration file
server=1
rpcuser=yourrpcuser
rpcpassword=yourrpcpassword
rpcallowip=127.0.0.1
rpcport=8332
prune=550
txindex=1
daemon=1
    
  • rpcuser and rpcpassword: You can set these to whatever you'd like (make them strong).

  • prune=550: This will set the node to prune the blockchain after 550MB (you can adjust this for more storage).

  • txindex=1: Ensures that transaction indexing is enabled (helps with querying).

Save and exit.

Step 7: Start Bitcoin Core

Now, start Bitcoin Core:

bitcoind -daemon
    

Step 8: Check Your Node’s Status

To check if Bitcoin Core is running, use:

bitcoin-cli getblockchaininfo
    

You should see information about the blockchain, indicating that your node is syncing.
