I have some reluctance towards ARK and Spark, they add a lot of complexity and Lightning is already complex, I mean from the developer's point of view.

To be honest I like Spark better than Ark, as Spark seems simpler.

I am looking forward to see how all these solutions including Mercury Layer are developed.

 That's why you have the vigilant Darthcoin 😄  

 Investigate WHO is behind Lightspark... then you will find out the truth.
