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 14.04 x64 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 14.04 x64)

Install dependencies

sudo apt-get update
sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils
sudo apt-get install libboost-all-dev
sudo apt-get install git
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:bitcoin/bitcoin
sudo apt-get update
sudo apt-get install libdb4.8-dev libdb4.8++-dev

Compile MultiChain for Ubuntu (64-bit)

./autogen.sh
./configure
make

Notes

• This will build multichaind, multichain-cli and multichain-util in the src directory.

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