Ardor (ARDR) is a blockchain platform that was launched in 2018 as a spin-off from the Nxt blockchain. It is designed to provide businesses and organizations with a scalable and customizable blockchain solution that can be used for a wide range of applications. Ardor uses a unique architecture that separates the blockchain into two layers: the Ardor parent chain and the child chains. The parent chain is responsible for maintaining the overall security and consensus of the network, while the child chains can be customized to meet the specific needs of different applications. This architecture allows for greater flexibility and scalability than traditional blockchain platforms, making Ardor an attractive option for businesses and organizations looking to implement blockchain technology.

One of the key features of Ardor is its ability to support multiple child chains, each with its own set of rules and parameters. This allows businesses and organizations to create their own customized blockchain solutions without having to build their own blockchain from scratch. Ardor also offers a range of other features, including built-in asset exchange, voting systems, and data cloud storage. Overall, Ardor is a promising blockchain platform that offers a range of features and benefits for businesses and organizations looking to implement blockchain technology.
