Ardor is Advanced Blockchain Technology

Scalable. Secure. Proven.
Ardor is an advanced blockchain platform ready to use, build and host the most inspired decentralized applications.
Proof of Stake Cryptocurrency


Ardor uses the first and the most secure PoS algorithm. It was first implemented in NXT and updated over time to become the only pure PoS in the blockchain space.



A Parent-Child Chain architecture where dApps can have a unique child chain inside a global blockchain ecosystem secured by the parent chain, Ardor.

Java Smart Contracts

Java Smart Contracts

Ardor has redefined the concept of Smart Contracts by introducing LightWeight Contracts – stateless, secure and extremely flexible smart contracts written in Java.



The previous features and others in development like Data Pruning, Subnet Networks and Zero-Knowledge Proofs all contribute to Ardor Blockchain Scalability.

Account Control

Ardor accounts can be augmented with properties and approval modals that make setting up a Multi-Sig wallet simple and very quick. These properties can represent account specific characteristics that dApps use to ensure that only accounts with some property can access their services.

Assets & Tokens

Decentralized Assets and Tokens available with simple clicks, can be fungible or non-fungible, they can exchangeable or not, their supply can be adjusted or not, and more features. A Decentralized Exchange is also supported and can allow automatic trading for the created assets/tokens.


Users are able to register combinations of letters and/or numbers, such as names and phone numbers, that are set to point to their Ardor account, so that other users can send to an alias instead of a long account number, a URL, or any piece of arbitrary data.

Decentralized Market Place

A Decentralized Market Place allows users to list items and purchase them. Auctions are natively supported, and users can post bids for an item.

Decentralized Messaging

Decentralized Messaging provides message capability between Ardor accounts. Arbitrary messages can be sent between accounts on their own or as part of a transaction. Messages can be encrypted and unlocked with the private key of either accounts as well as by any 3rd party with the shared key.

Decentralized Data cloud

Decentralized Cloud storage allows users to upload small files, such as small images and plain text files, into the blockchain itself. They can be accessed by anyone else. For private data, it is recommended to encrypt the file before uploading it.

Decentralized Monetary System

Through the Monetary System, users can create cryptocurrencies with special attributes normally associated with coins intended to be used for monetary purposes, such as requiring mining using SHA256, Scrypt, or multiple other mining algorithms, or making them controllable.

Decentralized Voting

Decentralized Voting allows polls to be created with up to 100 options for voters to choose from and the ability to require more than one option be chosen. Votes can be weighted or restricted according to  the amount of their balances. Alternative Voting systems are also possible where users can rank preferences with options provided.

Your dApp as a Service

Customize your childchain according to your needs

You may be wondering how to use blockchain technology to solve a major problem. You may not know where to start when you are faced with all the technical skills required to build your own blockchain or dApp.

Our technology, Ardor, is precisely designed to help you build your next dApp. Indeed, we can provide with your own childchain that you can setup with one or many of the available features described here — and many more coming through our next releases.

From idea to fully working DApp

The Ardor platform can tremendously reduce your Time-To-Market

Every dApp starts with an idea, a problem to solve or pain point to reduce.

You are welcome to share with us and our community to get fast and insightful feedback to enhance your solution.


Once your idea is fully designed you may want to start building it.

Ardor provides a full set of blockchain features that are ready to use and tools to explore them (API calls, Wallets, Smart Contracts, SQL Queries…), all you need is customize them to your needs. Our developers and community members are ready to assist you.


When your blockchain project is ready for deployment, then you can either choose to launch it as a new child chain with the help of Ardor developers or you can choose to deploy as a dApp on an existing child chain like Ignis. In either case you don’t have to care about maintaining a large set of full nodes.


Your DApp is deployed and fully working within a relatively short amount of time and effort.

Now you can focus on fully engaging with your users and iterating on your DApp so that you can serve them with an outstanding blockchain solution.
