Ardor is a platform that offers blockchain as a service to Businesses, unlike Bitcoin, which is a cryptocurrency and a worldwide payment system. It works utilizing blockchain technology of NXT (a cryptocurrency) and creating child chains using it which are customizable to some extent.
So basically Ardor operates with the help of two chains – parent chain and child chain. The parent chain i.e. Ardor is responsible for providing security to the Ardor platform and all its child chains. It does not have many features due to which it is lightweight and fast. On the other hand, child chains have a lot of features such as creating assets, sending messages, etc. which Businesses can utilize without developing anything and they won’t have to set up nodes or do mining for security, as the Ardor block-chain will do it for them.
Jelurida is the company behind the Ardor blockchain platform and Nxt Blockchain technology. The creation of the Ardor platform was announced in 2016 and it was launched on 1st Jan 2018.
