What is IPChain

IPChain is a decentralized blockchain project built on Bitcoin's UTXO model, secured by proof of delegated proof of contribution consensus model, and support intellectual property protection and intellectual property business. It achieves this through the revolutionary extended transation model, effective consensus mechanize and so on. For more general information about IPChain as well as links to join our community, go to

Welcome to the IPChain Main Network. This is the main network where the tokens hold value and should be guarded very carefully. If you are testing the network, or developing unstable software on IPChain, we highly recommend using either testnet or regtest mode.

The major features of the IPChain network include:

  1. Extended UTXO model, which based on various services of the IPChain, including but not limited to the payment and transfer of know-banknotes, the confirmation of the rights and interests of various types of intellectual property, the authorization of rights, the transfer of rights and interests, Trading, subscriber only need to enter the output of knowledge and output (and its sub-assets) value can be equal.

  2. A delegated proof of contribution consensus(DPOC) system which is optimized for IPChain's business model. Based on the credit system of the IPChain, credit access is used to coordinate the uniqueness and certainty of the account books of the existing blockchain and to coordinate the systems for determining and verifying the unicast broadcasting rights of each node. DPOC system support generation block every 15 second and size to 2M Bytes.

  3. Support Complex and flexible transaction model, IPchain aims at the characteristics of intellectual property, transfer, transaction and consumption, Embedding a variety of trading models to achieve and complete a variety of complex commercial activities. Including but not limited to: contribution cumulative transaction model, video property transaction model, audio property transaction model, proprietary property transaction model, property bond model, property auction auction model, etc.

  4. The Decentralized Governance Protocol is completely implemented and functional, which allows certain network parameters to be modified without a fork or other network disruption. This currently controls parameters like block size, etc.

Note: IPChain Core is considered beta software. We make no warranties or guarantees of its security or stability.

What is IPChain Core?

IPChain Core is IPchain's primary mainnet wallet. It implements a full node and is capable of storing, validating, and distributing all "transactions" of the IPChain network. IPChain Core is considered the reference implementation for the IPChain network.

IPChain Core currently implements the following:

  • Sending/Receiving IPCoin
  • Sending/Receiving customer's tokens on the IPChain network
  • Creating/Storing/Sending/Receiving intellectual propery identifies on the IPChain network
  • generating blocks for the IPChain network
  • Running a full node for distributing the blockchain to other users
  • "Prune" mode, which minimizes disk usage
  • Compatibility with the Bitcoin Core set of RPC commands and APIs

Building IPChain Core

Build on Ubuntu16.04

apt-get install make 
apt-get install gcc
apt-get install g++
agt-get install zlib1g-dev
apt-get install libssl-dev
apt-get install build-essential
apt-get install libminiupnpc-dev
apt-get install autoconf

sudo apt-get install libdb5.3++-dev
sudo apt-get install qt4-dev-tools qt4-doc qt4-qtconfig qt4-demos qt4-designer
sudo apt-get install libboost-all-dev
sudo apt-get install gcc-multilib
sudo apt-get install libprotobuf-dev
sudo apt-get install libevent-dev
sudo apt-get install protobuf-compiler

Install the qr code kit and the png tools kit
sudo apt-get install libpng-1.6.31 qrencode-3.4.4

git clone --recursive
cd ipchain

./configure --with-incompatible-bdb 
make install 

Build on CentOS7.3

yum install make
yum install gcc
yum install gcc-c++
yum install zlib-devel
yum install openssl-devel
yum groupinstall "Development Tools"

Download&Install miniupnpc library		
wget -O miniupnpc-1.6.20120509.tar.gz
tar -zxvf miniupnpc-1.6.20120509.tar.gz
cd miniupnpc-1.6.20120509
make install 

Download&Install Boost library
tar zxvf boost_1_59_0.tar.gz 
cd  boost_1_59_0
./b2 install

Add boost.conf file in the /etc/ directory 
cd /etc/
vi boost.conf

Add following content in boost.conf

yum install libevent-devel
yum install protobuf-devel
yum install protobuf-compiler

git clone
cd ipchain
./configure --with-incompatible-bdb 

Build on OSX

The commands in this guide should be executed in a Terminal application. The built-in one is located in /Applications/Utilities/


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 --c++11 --without-single --without-static miniupnpc openssl pkg-config protobuf qt5 libevent imagemagick --with-librsvg

NOTE: Building with Qt4 is still supported, however, could result in a broken UI. Building with Qt5 is recommended.

Build IPChain Core

  1. Clone the IPChain source code and cd into ipchain:

     git clone --recursive
     cd ipchain
  2. Build ipchain core:

    Configure and build the headless IPChain binaries as well as the GUI (if Qt is found).

    You can disable the GUI build by passing --without-gui to configure.

  3. It is recommended to build and run the unit tests:

     make check


Then you can either run the command-line daemon using src/ipchain and ipchain-cli, or you can run the Qt GUI using src/qt/ipchain-qt
