Issa a yellow aim icon there.

but here I’m thinking more from the pov of wanting to see a lack of actions by operators who claims that.

I’m no cryptographer, maybe it needs more complications, maybe those complications could be tied to some proof that the operator is in a v4v share with the writer of the implementation, and the receipt key is some derivative, because I’m mostly looking for the absence of action to verify that sales pitch is true.

but maybe it’s as simple as being familiar with how the implementation handles white and black lists and then format those so clients or relay explorers like .watch could surface them in a standard way. Maybe there is a way I can ping an implementation to return the list that I’m not familiar with. But I’m not speaking about making it easy to interope this data else where.
