Interesting new service @cardboard / @acidyo. Reading "between the lines," it would lead one to believe this is a proposed "workaround" from some of the perceived limitations of HF 21 / 22.
If so, what are your thoughts on the prospect of simply addressing these with some EIP changes in the next HF?
Beyond that, my general impression is the use of @reward.app adds another layer(s) of complexity, which takes us in the opposite direction from what would likely help us with newcomers.
So ...
If there is a better and more accommodating team on the Hive blockchain that the @peakd team, I am unaware of them. I would suggest you get with them and, if they are agreeable, "hide" as much of this complexity inside PeakD as possible ...
My $0.02 ... 👋
That's the plan ;)
