# 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
