# Running Bitcoin Cash node

# BCHN on Ubuntu

Create a directory for the data (it should have ~210G free space as of Nov 2020), let's say: /mnt/bchn

# Remove Bitcoin ABC if it was running

sudo apt-get remove bitcoind bitcoin-qt bitcoin-tx
sudo add-apt-repository --remove ppa:bitcoin-abc/ppa

# Install Bitcoin Cash Node

# Run this Ubuntu 16.04 and 18.04 only:

sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install g++-7

Install the node:

sudo add-apt-repository ppa:bitcoin-cash-node/ppa
sudo apt-get update
sudo apt-get install bitcoind

# Start Bitcoin Cash Node

bitcoind -datadir=/mnt/bchn -rpcallowip=127.0.0.1 \
    -rpcbind=127.0.0.1:8332 -rpcuser=rpc \
    -rpcpassword=dqwaDOvqEqxkIsD9oQCZA2lOagPpHuYM \
    -txindex=1

Replace the password with something random (try head /dev/urandom | tr -dc A-Za-z0-9 | head -c 32 ; echo '' on Linux)

To open your RPC for other computers on the Internet (not recommended, even if password protected):

bitcoind -datadir=/mnt/bchn -rpcallowip=0.0.0.0/0 \
    -rpcbind=0.0.0.0:8332 -rpcuser=rpc \
    -rpcpassword=dqwaDOvqEqxkIsD9oQCZA2lOagPpHuYM \
    -txindex=1

# Running Fulcrum (Electron Cash compatible server)

Generate an SSL certificate (needed for the protocol, self-signed is sufficient, enter any values you'd like):

openssl req -newkey rsa:4096 \
    -x509 -sha256  -days 3650  -nodes \
    -out /var/www/tls/fulcrum-certificate.pem \
    -keyout /var/www/tls/fulcrum-key.pem

Install Fulcrum (replace 1.3.1 with the latest (opens new window) version)

wget https://github.com/cculianu/Fulcrum/releases/download/v1.3.1/Fulcrum-1.3.1-x86_64-linux.tar.gz
tar zxvf Fulcrum-1.3.1-x86_64-linux.tar.gz
rm Fulcrum-1.3.1-x86_64-linux.tar.gz
cd Fulcrum-1.3.1-x86_64-linux

./Fulcrum --datadir=/mnt/bchn \
  --bitcoind=127.0.0.1:8332 --rpcuser=rpc \
  --rpcpassword=dqwaDOvqEqxkIsD9oQCZA2lOagPpHuYM \
  --ssl=0.0.0.0:50002 \
  --cert=/var/www/tls/fulcrum-certificate.pem --key=/var/www/tls/fulcrum-key.pem
