Zilliqa is a scalable smart contract platform that aims to tackle the congestion issue plaguing the blockchain industry. Zilliqa utilises a unique sharded architecture to achieve parallel processing of transactions while maintaining a large number of public nodes. Hence, Zilliqa is a blockchain capable of reaching high throughput and processing more complex computations while remaining decentralised and secure.

NOTE: The master branch is not for production as development is currently being worked constantly, please use the tag releases if you wish to work on the version of Zilliqa client that is running live on the Zilliqa blockchain.

Zilliqa Mainnet

The current live version on the Zilliqa Mainnet is Zilliqa v9.2.3 and Scilla v0.13.3.

Available Features

The current release has the following features implemented:

In the coming months, we plan to have the following features:

  • Further unit and integration tests
  • Enhancement of existing features
  • More operating system support
  • And much more...

Minimum System Requirements

To run Zilliqa, we recommend the minimum system requirements specified in our Mining page.

Build from Source Code

Starting with Zilliqa v8.6.0, the officially supported operating system is Ubuntu 22.04.

If you'd like to experiment with a different distro (including the previously supported Ubuntu 18.04), please make sure to install gcc >= 11.

Run the following to install the build dependencies:

sudo apt-get update
sudo apt-get install autoconf \
    build-essential \
    ccache \
    clang-format \
    clang-tidy \
    git \
    lcov \
    libcurl4-openssl-dev \
    libssl-dev \
    libtool \
    libxml2-utils \
    ninja-build \
    ocl-icd-opencl-dev \
    pkg-config \
    python3-dev \
    python3-pip \
    libgmp-dev \
    bison \
git submodule update --init --recursive

Run the following to install latest version of cmake. CMake version >= 3.19 must be used:

mkdir -p "${HOME}"/.local
bash ./ --skip-license --prefix="${HOME}"/.local/
export PATH=$HOME/.local/bin:$PATH
cmake --version

To install, clone vcpkg to a separate location (do not use brew on macos):

$ git clone /path/to/vcpkg
$ cd /path/to/vcpkg && git checkout 2022.09.27 && ./
$ cd /path/to/zilliqa
$ export VCPKG_ROOT=/path/to/vcpkg

As part of building our source code, we patch websocketpp 0.8.2 to compile on C++20; please see the license:

Build Zilliqa from the source:

# build Zilliqa binary
$ ./

If you want to contribute by submitting code changes in a pull request perform the build with clang-format and clang-tidy enabled by doing:

$ ./ style

Build Scilla for Smart Contract Execution

The Zilliqa client works together with Scilla for executing smart contracts. Please refer to the Scilla repository for build and installation instructions.

Boot Up a Local Testnet for Development

  1. Run the local testnet script in build directory:

    $ cd build && ./tests/Node/ && ./tests/Node/ && ./tests/Node/
  2. Logs of each node can be found at ./local_run

  3. To terminate Zilliqa:

    $ pkill zilliqa

Start a local network development environment

This is similar to the above, but deploys a local testnet to a local minikube cluster.

You can find documentation on how to do this on your local machine in docs/

You can find scripts which will set up an Ubuntu 22.04 machine in the cloud (or install necessary dependencies on your machine) in docs/setup/
