Alex. You are working with Ark, right? Setting aside all of the complicated L2 stuff, unilateral exit, etc... A basic question -- is Ark allowing other companies (besides Ark) to run services? And, when a user runs Ark, do they have no option but to hit GraphQL or HTTP endpoints controlled by Ark? Here is the relevant issue we opened on Spark 
-- it seems that right now, if you use Spark, then @David Marcus gets all your transaction data -- which might be sketchy for users who are at political risk or for whom transaction privacy is important. Anything you can add from the perspective of Ark? Because, like, Ark is trying to solve similar problems that Spark is, right?
