Native rollups vs Based rollups

Hi!

Can someone explain it to me? This topic has been discussed a few times and recently in Bankless podcast. But it is still very complex to me.

Some questions I have in mind: – What's the problems L2 landscape is facing right now? – What are Native rollups? Based rollups? What solution(s) to they offer to fix these problems? – What are the differences between both? – How do they work? – What are the challenges with these 2 solutions?

Thanks!
