Create Bitcoin core config

mkdir -p ~/.bitcoin
vim ~/.bitcoin/bitcoin.conf

Add the following into the file

### PRUNED NODE ###
prune=550           # ~5.5 GB (minimum)
txindex=0

### RPC ###
server=1
rpcbind=127.0.0.1
rpcallowip=127.0.0.1

### TOR-ONLY NETWORKING ###
proxy=127.0.0.1:9050
onlynet=onion
listen=1
dnsseed=0

### TOR CONTROL (optional but recommended) ###
torcontrol=127.0.0.1:9051
torpassword=your_tor_control_password

### PRIVACY ###
listenonion=1
discover=0
upnp=0
natpmp=0

### PERFORMANCE ###
dbcache=300
maxconnections=12

Start the node:

bitcoind -daemon

Check status:

bitcoin-cli getblockchaininfo

you should see:

"pruned": true

Check Tor usage:

bitcoin-cli getnetworkinfo

Look for:

"network": "onion"

Run at Boot with Systemd

Restart=always

[Install]
WantedBy=multi-user.target

Reload

sudo systemctl daemon-reload
sudo systemctl enable bitcoind
sudo systemctl start bitcoind

Verify Everything is Working

bitcoin-cli getnetworkinfo
bitcoin-cli getpeerinfo
bitcoin-cli getmempoolinfo
