What is Ardor?
Ardor was released in 24 November 2017 by Jean-Luc and Lior Yaffe. Ardor blockchain is used as a parent chain where, other new child chains are created on it. Every child chain can have its own features without the users needing main chain coin to use it, while being secured by the main chain. All transactions from all chains must be processed by all Ardor nodes and these nodes carry all child chain transactions for the last 1440 blocks. Only the parent chain token is used in the proof-of-stake consensus, and thus provides security for all child chains. All the Ardor coins are premined, meaning you cannot create more coins from mining. Ardor can handle up to 100 transactions per second.
