Another thing about Ardor as a parent blockchain that is responsible for the security and transactions of child chain is that it allow all the child chains to own their native tokens that will be used as a unit of value and for paying transaction fees and other assign features. I like the fact that Ardor has a BUNDLING SYSTEM that process all transaction of child chain on the parent blockchain and allow application owners to sponsor transaction fees for their users. Apart from being 100% proof-of-stake consensus algorithm as mentioned in my review the token is also use for FORGING i.e to generate new blocks and network consensus whereas ARDR forgers receive the transaction fees from the blocks forged and no new ARDR will be created
