What's the difference between Ardor and Ignis?
Ardor is the parent chain, Ignis is the child chain. Ignis runs on top of the Ardor parent chain. One is meant to be the reserve currency while the other the day to day transactional currency.
Thanks. More questions:
A) Why make them separate?
B) What is the block time on Ardor and Ignis.
C) Has one of them have smart contracts?
E) Can you send cross-chain transactions?
F) Can you sync one of them or do you need to keep getting blocks from both chains?
