MultiChain
MultiChain is an open source platform for private blockchains, which offers a rich set of features including extensive configurability, rapid deployment, permissions management, native assets and data streams. Although it is designed to enable private blockchains, MultiChain provides maximal compatibility with the bitcoin ecosystem, including the peer-to-peer protocol, transaction/block formats and Bitcoin Core APIs/runtime parameters.

System requirements
These compilation instructions have been tested on Ubuntu 16.04 x64 (xenial) and Ubuntu 18.04 x64 (bionic) only.
C++ compilers are memory-hungry, so it is recommended to have at least 1 GB of memory available when compiling MultiChain. With less memory, compilation may take much longer due to swapfile thrashing.
Linux Build Notes (on Ubuntu 16.04 x64 or later)
Install dependencies
sudo apt-get update
sudo apt-get install -y software-properties-common
sudo apt-get install -y build-essential libtool autotools-dev automake pkg-config libssl-dev git python python-pip

Clone MultiChain
git clone https://github.com/MultiChain/multichain.git
Prepare to download or build V8
cd multichain
set MULTICHAIN_HOME=$(pwd)
mkdir v8build
cd v8build
You can use pre-built headers and binaries of Google's V8 JavaScript engine by downloading and expanding linux-v8.tar.gz in the current directory. If, on the other hand, you prefer to build the V8 component yourself, please follow the instructions in V8.md.
Compile MultiChain for Ubuntu (64-bit)
cd $MULTICHAIN_HOME
./autogen.sh
./configure
make
Notes
-
This will build

The release is built with GCC after which
strip multichaindstrings the debug symbols, which reduces the executable size by about 90%.
