Zcoin v0.13.7.5

Build Status

What is Zcoin?

Zcoin is the first full implementation of the Zerocoin Protocol, which allows users to have complete privacy via Zero-Knowledge cryptographic proofs. It is worth noting that Zcoin is unrelated to other cryptocurrencies utilizing the Zerocash Protocol. Although Zerocash is a development from Zerocoin, their respective implementations are not simple forks of each other, but rely on different cryptographic assumptions with various tradeoffs. Both approaches supplement each other quite nicely, and a good way to describe them would be sibling projects.

The Zerocoin Protocol is being actively researched and improved, such as removing the trustless setup and reducing proof sizes.

Running with Docker

If you are already familiar with Docker, then running Zcoin with Docker might be the the easier method for you. To run Zcoin using this method, first install Docker. After this you may continue with the following instructions.

Please note that we currently don't support the GUI when running with Docker. Therefore, you can only use RPC (via HTTP or the zcoin-cli utility) to interact with Zcoin via this method.

Pull our latest official Docker image:

docker pull zcoinofficial/zcoind

Start Zcoin daemon:

docker run --detach --name zcoind zcoinofficial/zcoind

View current block count (this might take a while since the daemon needs to find other nodes and download blocks first):

docker exec zcoind zcoin-cli getblockcount

View connected nodes:

docker exec zcoind zcoin-cli getpeerinfo

Stop daemon:

docker stop zcoind

Backup wallet:

docker cp zcoind:/home/zcoind/.zcoin/wallet.dat .

Start daemon again:

docker start zcoind

Linux Build Instructions and Notes

Dependencies

  1. Update packages

    sudo apt-get update
    
  2. Install required packages

    sudo apt-get install build-essential libtool autotools-dev automake pkg-config libssl-dev libevent-dev bsdmainutils libboost-all-dev
    
  3. Install Berkeley DB 4.8

    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
    
  4. Install QT 5

    sudo apt-get install libminiupnpc-dev libzmq3-dev
    sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libqrencode-dev
    

Build

  1. Clone the source:

    git clone https://github.com/zcoinofficial/zcoin
    
  2. Build Zcoin-core:

    Configure and build the headless Zcoin 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
    make
    
  3. It is recommended to build and run the unit tests:

    make check
