# Zilliqa
## Overview
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.
* If you’re interested in mining Zilliqa, see here: https://dev.zilliqa.com/docs/miners/mining-getting-started/.
* If you’d like to use the interface with Zilliqa nodes to transfer ZIL and deploy/call smart contracts, see here: https://dev.zilliqa.com/docs/apis/api-introduction.
* If you’re interested more about the core protocol, see the [developer portal](https://dev.zilliqa.com/docs/contributors/contribute-buildzil).
* If you’re interested in hacking on the Zilliqa code base, see the [Coding Guidelines](https://github.com/Zilliqa/Zilliqa/wiki/Coding-Guidelines).
> **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.

## Minimum System Requirements
To run Zilliqa, we recommend the minimum system requirements specified in our [Mining](https://dev.zilliqa.com/docs/miners/mining-zilclient#hardware-requirements) page.
## Build from Source Code
Starting with Zilliqa [v8.6.0](https://github.com/Zilliqa/Zilliqa/releases/tag/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:
```bash
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 \
gawk
git submodule update --init --recursive
```
Run the following to install latest version of cmake. CMake version >= 3.19 must be used:
```
wget https://github.com/Kitware/CMake/releases/download/v3.19.3/cmake-3.19.3-Linux-x86_64.sh
mkdir -p "${HOME}"/.local
bash ./cmake-3.19.3-Linux-x86_64.sh --skip-license --prefix="${HOME}"/.local/
export PATH=$HOME/.local/bin:$PATH
cmake --version
rm cmake-3.19.3-Linux-x86_64.sh
```
To install, clone vcpkg to a separate location (do not use brew on macos):
```shell
$ git clone https://github.com/Microsoft/vcpkg.git /path/to/vcpkg
$ cd /path/to/vcpkg && git checkout 2022.09.27 && ./bootstrap-vcpkg.sh
$ 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: https://github.com/zaphoyd/websocketpp/blob/master/COPYING.
Build Zilliqa from the source:
```shell
# build Zilliqa binary
$ ./build.sh
```
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:
```shell
$ ./build.sh style
```
## Build Scilla for Smart Contract Execution
The Zilliqa client works together with Scilla for executing smart contracts. Please refer to the [Scilla repository](https://github.com/Zilliqa/scilla) for build and installation instructions.
## Boot Up a Local Testnet for Development
1. Run the local testnet script in `build` directory:
```shell
$ cd build && ./tests/Node/pre_run.sh && ./tests/Node/test_node_lookup.sh && ./tests/Node/test_node_simple.sh
```
2. Logs of each node can be found at `./local_run`
3. To terminate Zilliqa:
```shell
$ 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/localdev.md`.
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/README.md`.
