Yeah I think they are still building out the stack. But you make a good point that graphic is a bit busy but they are showing the total ecosystem of the atomic economy from identity, to chat, to payments while the other solutions he critiques is complex just for payments. Ark, liquid and e-cash don’t have an identity or chat/apps layer.
I was excited when Bitkit first came out as well. I tried playing around with it then, but it had too many features to be the lightning wallet I wanted and yet the extra features weren't built out enough to be engaging.
Synonym is interesting to me exactly because they aren't working on the same ol' same ol' lightning wallet LSP kind of thing (and because Carvalho is interesting). But I haven't been too enthralled with Pubky, either.
