Ardor is a blockchain-as-a-service platform built on the Nxt blockchain technology. It allows you to create child chains with their own tokens which rely on the main Ardor chain to power and secure them. This makes creating your own blockchain much easier since the Ardor main chain provides everything you’ll need (including nodes). All child chains will be able to interact with the main Ardor chain and other child chains. The Nxt technology offers various features, including: aliases, cloud storage, account control, secure messaging, plugins, and a marketplace. The main chain is optimized with minimal features in order to streamline it. It utilizes a proof-of-stake protocol and therefore doesn’t need miners or nodes. Ardor (ARDR) is the token that resides on the main Ardor chain and can be used to pay transaction fees.
