What is Hush?

Hush implements Extreme Privacy via blockchain tech. We have our own genesis block. We are not a chain fork (copy) of another coin. We are based on Bitcoin code, with sophisticated zero-knowledge mathematics added for privacy. This keeps your transaction metadata private!

What is this repository?

This software is the Hush node and command-line client. It downloads and stores the entire history of Hush transactions; depending on the speed of your computer and network connection, it will likely take a few hours at least, but some people report full nodes syncing in less than 1.5 hours.

Banned by GitHub

In working on this release, Duke Leto was suspended from Github, which gave Hush developers the impetus to completely leave that racist and censorship-loving platform. Hush now has it's own git.hush.is Gitea instance, because we will not be silenced by Microsoft. All Hush software will be released from git.hush.is and hush.is, downloads from any other domains should be assumed to be backdoored.

Hush is unfinished and highly experimental. Use at your own risk! Just like Bitcoin.

Build on Debian or Ubuntu

Install on ARM Architecture

Use this if you have a Raspberry Pi or similar computer. 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 old RaspberryPi devices will not work, unless they have a newer ARMv8-based Raspberry Pi. Raspberry Pi 4 and newer are known to work.

1. Download the latest Debian package with the AARCH64 designation from the releases page.
2. Install the Debian package, substituting "VERSION-NUMBER" for the version you have downloaded: sudo dpkg -i hush-VERSION-NUMBER-aarch64.deb.
3. Run with: hushd.

Building On Ubuntu 16.04 and older systems

Some older compilers may not be able to compile modern code, such as gcc 5.4 which comes with Ubuntu 16.04 by default. Here is how to install gcc 7 on Ubuntu 16.04. Run these commands as root:

add-apt-repository ppa:ubuntu-toolchain-r/test && \
apt update && \
apt-get install -y gcc-7 g++-7 && \
  update-alternatives --install /usr/bin/g++ g++ /usr/bin/g++-7 60 && \
  update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-7 60

Build on Mac

sudo port update
sudo port upgrade outdated
sudo port install qt5

# clone git repo
git clone https://git.hush.is/hush/hush3
cd hush3
# Build
# This uses 3 build processes, you need 2GB of RAM for each. 
./build.sh -j3

Installing Hush binaries

1. Download the release with a .deb file extension.
2. Install the Debian package, substituting "VERSION-NUMBER" for the version you have downloaded: sudo dpkg -i hush-VERSION-NUMBER-amd64.deb.
3. Run with: hushd.

Windows (cross-compiled on Linux)

Get dependencies:

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

Downloading Git source repo, building and running Hush:

# pull
git clone https://git.hush.is/hush/hush3
cd hush3
# Build
./util/build-win.sh -j$(nproc)
# Run a HUSH node
./src/hushd

What is SilentDragon?

• SilentDragon is a desktop wallet for HUSH full node.
  
• SilentDragonLite is a desktop wallet that does not require you to download the full blockchain.
• SilentDragonAndroid is a wallet for Android devices.
• SilentDragonPaper is a paper wallet generator that can be run completely offline.

What is HushChat?

HushChat is a protocol inspired by the design of Signal Protocol, it uses many of the same cryptography and ideas, but does not actually use any code from Signal. Signal requires phone numbers and is a centralized service. HushChat is completely anonymous and decentralized and requires absolutely no metadata be given to any centralized third parties.

Can I mine with CPU or GPU?

Hush cannot be efficiently mined with CPU or GPU, only ASIC mining is recommended. HUSH uses Equihash (200,9) algo, as does Zcash, Horizen or Komodo.
