Nimiq: the Blockchain for JS Devs!

Nimiq is the first browser blockchain. That means apps based on Nimiq can run directly in the browser of the user, locally, installation-free, without the need of a server-side application. And if you have a server-side application, you can use the Nimiq Node.js client. This way, it can be easily integrated into any existing app. Syncing with Nimiq requires seconds, not hours and it works on low-bandwidth. Ideal for mobile and progressive web-apps.

  • You can create blockchain-enabled applications in JS without a third party to rely on
  • No dependencies on external services, your app is a full member of the Nimiq network
  • No service fees, terms of use, rules, and restrictions
  • Everything open source and licensed under MIT and Apache 2.0 license
  • Create a blockchain powered app and deploy it, or
  • Add NIM payments to any existing app

Start building blockchain-enabled apps with your JS skills using the resources of Nimiq:

Get Started

Build your own Nimiq-enabled app. Step by step with code snippets and a full running example at the end of each tutorial.

Quick Start

You can set up a Nimiq node within your browser that will connect to the Nimiq network and reach consensus in basically three lines of JavaScript code:

<script src="https://cdn.nimiq.com/latest/nimiq.js"></script>
<script>
    Nimiq.load().then(async function() {

        // Configure for Testnet. For Mainnet, use main().
        Nimiq.GenesisConfig.test();

        // Instantiate a config builder.
        const configBuilder = Nimiq.Client.Configuration.builder();

        // Create a client based on your configuration,
        // it will automatically connect to the network.
        const client = configBuilder.instantiateClient();
    });
</script>

But there is more! Learn in the tutorials below how to build a small webapp with JavaScript, HTML, and CSS that manages a wallet, sends and receives transactions, and looks neat using Nimiq's CSS framework.

App Starter Kit

Just clone the App-Starter Kit repo on GitHub and get the entire infrastructure for creating a Nimiq-enabled app with Vue.js setup, and the Nimiq client, Identicons, custom Nimiq components for Vue.js, the Hub API, Nimiq Style and more. Checkout the readme and the demo to see what it's capable of! To understand better how to use each part, have a look at the tutorials below.

Run a node

The minimum example: On Linux and Mac, all you need is an IP and an open or forwarded port to run a full node.

git clone https://github.com/nimiq/core-js.git nimiq && cd nimiq
yarn && yarn build
clients/nodejs/nimiq --host=IP --port=PORT --protocol=ws

Note: For further details and instructions for Windows users, refer to the Nimiq Core Documentation.

Run a miner: just add configuration for threads and address
