# 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!

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](https://git.hush.is/hush) 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.

```
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sudo port upgrade outdated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
