Haha well a week is not a long time (especially on a subject like this)!
I have spent a good deal of time on it though.
I should mention that I am more interested in computational privacy, rather than transactional privacy.
I’ve only done a real deep dive (how is that possible in a week) on some other layer one type projects and also projects that you would probably classify as being outside of “crypto”.
There is loads of cool stuff going on and it is very exciting for everyone - I’m not going to mention any other names as I’m not here to shill anything (don’t give a shit about tokens) and this is a Secret Network forum, not a general community interested in “privacy”.
But what is great is that there is real, useable solutions available right now and many more coming down the pipeline - it’s awesome to see this stuff finally coming together.
I haven’t delved much into layer 2 solutions yet - but already have a decent understanding of what is going on in that space.
I’m not sure about the “how far they are behind SN” part of your question - that wasn’t really what I have been researching.
Still got loads to research and plenty to learn - my initial question still stands, I’d love it if someone has done a real deep dive on this topic and can help me by referencing it here.
