Ardor (English name: Ardor) is the token of the NXT 2.0 system. The NXT team released the Ardor project (the NXT 2.0 token) in May 2016, and launched a new blockchain system with advanced features in 2017. Ardor ARDR was generated at a 1:1 snapshot from the old NXT, with a total supply of 1 billion tokens. The existing Ardor ARDR was produced during the snapshot of NXT conducted between July and October 2016.
Ardor is a scalable blockchain platform. Ardor addresses blockchain bloat by dividing NXT into a forging chain and prunable child chains. This allows the Ardor main chain to focus on protecting all child chains and processing transactions without conflicting with business operations on the child chains. Its scientific architecture makes Ardor the infrastructure for the entire NXT child chain ecosystem. Since it is built using NXT technology, NXTs features, such as asset exchange, dividend payments, messaging, voting, shuffling, and the currency system, will be available on the child chains. Additionally, users will be able to perform certain cross-link transactions between child chains on the platform. Users can issue their own child chains, allowing people to use blockchain technology without having to build the framework from scratch. Fast, scalable, secure, and reliable are the characteristics of Ardor, opening up a new world of possibilities for enterprise-level blockchain technology applications.

Project Highlights

1. Advanced Architecture
The unique parent-child architecture of the Ardor platform enables companies to build products and services using child chains while relying on the security provided by the parent chain.
2. Efficient and Energy-Saving
The Ardor platform uses a Proof-of-Stake consensus algorithm to eliminate mining competition, allowing nodes to use low-energy and cost-effective hardware.
3. Reliable and Maintainable Product
Ardor is built upon four years of production experience with NXT and is developed in Java, one of the most popular programming languages for commercial applications.
4. Speedy
Every block containing all child chains is packed in 60 seconds or less. Child chain transactions can be removed from the blockchain after confirmation to keep the actual blockchain lightweight and efficient.
5. Scalability
Child chain transaction data is pruned, making the block size independent of all child chains.
6. Security
Ardor is developed by Jelurida, the core development team behind NXT, which has been proven to be secure and stable.

Use Cases

1. Blockchain Services – Ardor will open up a blockchain development platform for organizations and individuals around the world. The high barrier to entry for blockchain will disappear.
2. Scalable Blockchain Capacity – By separating transactions and data that do not affect security, Ardor will address scalability issues by moving all such transactions and data onto child chains. The Ardor team will create the first child chain to accommodate many of the tools from NXT 1.0 as well as future features. This small size also means shorter transaction times, so processes take only a fraction of the time compared to Bitcoin.
3. Distributed Asset Exchange – Building on the asset exchange established on NXT, Ardor will enable the exchange of any child chain token assets on any child chain. This allows child chains to interact with each other and opens up many collaborative opportunities, enabling cross-chain asset trading, a long-requested feature in the NXT ecosystem.
4. Distributed Voting and Governance System – This will become the cornerstone of decentralized consensus in the future. Secure and anonymous voting will be a feature available on all child chains on the NXT platform.
5. Phased Transactions – Before executing a transaction, users can set multiple conditions, including the minimum number of votes and a set amount of time. Like NXT, Ardor will use smart transactions. Thus, users need only submit the parameters required for the transaction and the ID of the function to be used. The transaction process is fully decentralized. There is no need for centralized servers, services, or applications like Ethereums Oracle.
