Installing Hush

Download and Install Hush v2.0.0 Stable Release

This method can be used to install release packages:

cd ~
sudo wget https://github.com/MyHush/hush/releases/download/v2.0.0/hush-2.0.0-c7d6ba61-amd64.deb
sudo dpkg -i hush-2.0.0-c7d6ba61-amd64.deb

To install Hush from source, read on.

Build HUSH dependencies

The following build process generally applies to Ubuntu (and similar) Linux distributions. For best results it is recommended to use Ubuntu Linux 16.04 or later.

Swap Space (Optional)

You will need at least 4GB of RAM to build hush from git source, OR you can enable a swap file. To enable a 4GB swap file on modern Linux distributions:

sudo fallocate -l 4G /swapfile
sudo chmod 600 /swapfile
sudo mkswap /swapfile
sudo swapon /swapfile

Build on Linux:

# install build depedencies
sudo apt-get install build-essential pkg-config libc6-dev m4 g++-multilib \
      autoconf libtool ncurses-dev unzip git python zlib1g-dev wget \
      bsdmainutils automake curl unzip nano
# pull
git clone https://github.com/MyHush/hush.git
cd hush
# Build
./zcutil/build.sh -j$(nproc)

Download proving key:

./zcutil/fetch-params.sh

Create a HUSH configuration file (important):

You can compile Hush without this, but need a config file to run hushd.

mkdir -p ~/.hush
echo "rpcuser=username" >> ~/.hush/hush.conf
echo "rpcpassword=`head -c 32 /dev/urandom | base64`" >>~/.hush/hush.conf
echo "addnode=explorer.myhush.org" >> ~/.hush/hush.conf
echo "addnode=dnsseed.myhush.org" >> ~/.hush/hush.conf
echo "addnode=dnsseed2.myhush.org" >> ~/.hush/hush.conf
echo "addnode=dnsseed.bleuzero.com" >> ~/.hush/hush.conf
echo "addnode=dnsseed.hush.quebec" >> ~/.hush/hush.conf

Run a HUSH Node

./hushd

Windows (cross-compiled on Linux)

Get dependencies:

sudo apt-get install \
      build-essential pkg-config libc6-dev m4 g++-multilib \
      autoconf libtool ncurses-dev unzip git python \
      zlib1g-dev wget bsdmainutils automake mingw-w64 cmake

Downloading Git source repo, building and running Hush:

# pull
git clone https://github.com/MyHush/hush.git
cd hush
# fetch key
./zcutil/fetch-params.sh
# Build
./zcutil/build-win.sh -j$(nproc)
# Run a HUSH node
./src/hushd

Mac

Install Xcode CLI tools:

xcode-select --install

Downloading Git source repo, building and running Hush:

# pull
git clone -b v2.0.0 https://github.com/FireMartZ/hush-apple.git
cd hush-apple
source environment
make
# Run a HUSH node
./src/hushd

Make sure to create a HUSH configuration file as described above.

Supported Platforms

Currently Linux, Windows and Mac OS X are our supported platforms. If you are interested in porting Hush to a new operating system, we are interested to talk with you.

We aim to support all platforms, but there is only so much time in the day.

Currently, any ARMv7 machine will not be able to build this repo, because the underlying tech (zcash and the zksnark library) do not support that instruction set.

This also means that RaspberryPi devices will not work, unless they have a newer ARMv8-based Raspberry Pi.
