Ignis is the first Ardor Child Chain

It has nothing to do with Ethereum/Plasma/Snarks

Ignis — the first child chain of Ardor

Ignis is the first child chain of Ardor and has been in production since 1/1/2018. It has already implemented most of the promises of the Ethereum Plasma architecture - but on the Ardor blockchain, not on Ethereum. On January 9th, 2019 Ignis is about to receive a major upgrade with the introduction of our lightweight contracts solution on mainnet.
