The HYDRA Blockchain is a hybrid utilizing the transaction model of Bitcoin and employing the powerful virtual machine of Ethereum. It is based on the Bitcoin Core, Ethereum and Qtum. It features a Proof of Stake consensus mechanism, high transaction throughput, democratic governance of key parameters, predictable network fees and a unique profit-sharing system.

Here is a brief description for compiling HYDRA on CentOS
# Compiling boost manually
sudo yum install python-devel bzip2-devel
git clone https://github.com/boostorg/boost.git
cd boost
git checkout boost-1.66.0
git submodule update --init --recursive
./bootstrap.sh --prefix=/usr --libdir=/usr/lib64
./b2 headers
sudo ./b2 -j4 install
# Installing Dependencies for HYDRA
sudo yum install epel-release
sudo yum install libtool libdb4-cxx-devel openssl-devel libevent-devel gmp-devel
# If you want to build the Qt GUI:
sudo yum install qt5-qttools-devel protobuf-devel qrencode-devel
# Building HYDRA
git clone https://github.com/Hydra-Chain/node.git --recursive HYDRA
cd HYDRA
./autogen.sh
./configure
make -j4
The commands in this guide should be executed in a Terminal application.
The built-in one is located in /Applications/Utilities/Terminal.app
.
Install the OS X command line tools:
xcode-select --install
When the popup appears, click Install
.
Then install Homebrew.
brew install cmake automake berkeley-db4 libtool boost@1.76 miniupnpc openssl pkg-config protobuf qt5 libevent imagemagick librsvg qrencode gmp
NOTE: Building with Qt4 is still supported, however, could result in a broken UI. Building with Qt5 is recommended.

Clone the HYDRA source code and cd into
HYDRA
git clone https://github.com/Hydra-Chain/node.git --recursive HYDRA cd HYDRA
-
Build HYDRA:
Configure and build the headless HYDRA binaries as well as the GUI (if Qt is found).
You can disable the GUI build by passing
--without-gui
to configure../autogen.sh ./configure --with-boost=/usr/local/Cellar/boost@1.76/1.76.0_2 make
export DYLD_LIBRARY_PATH=/usr/local/Cellar/boost@1.76/1.76.0_2/lib
Then you can either run the command-line daemon using src/hydrad
and src/hydra-cli
, or you can run the Qt GUI using src/qt/hydra-qt
