City Chain is a blockchain implementation that supports the Bitcoin protocol in C# and runs on .NET Core, and is based on the Stratis and NBitcoin source code.

The City Chain is built to be the foundation network for the Smart City Platform.

City Chain is a Proof-of-Stake (PoS) blockchain, on which individuals who provide staking ("mining") are randomly selected to perform the task of signing the individual blocks in the chain. For this service, the individuals receive City Coin (CITY). City Coin is the currency on the City Chain and Smart City Platform. The Smart City Platform will support different crypto-currencies, not just City Coin.

City Chain is available for Windows, Mac and Linux. You can download the City Chain daemon on the releases page.

We encourage as many as possible to run public City Chain nodes, to help support our network.

You can run City Chain directly from source code. This is not advisable for most normal uses, as the code might be unstable.

git clone https://github.com/CityChainFoundation/city-chain.git
cd city-chain\src

dotnet restore
dotnet build

To run on the test network:

cd City.Chain
dotnet run -testnet

There is a lot to do and we welcome contributers developers and testers who want to get some Blockchain experience.

Specification and API reference for source code is published to https://www.citychainfoundation.github.io/city-chain/.

• Testing Guidelines

We use Azure DevOps for our CI build and to create nuget packages. Every time someone pushes to the master branch or create a pull request on it, a build is triggered and new nuget packages are created.

To skip a build, for example if you've made very minor changes, include the text [skip ci] or [ci skip] in your commits' comment (with the squared brackets).
