I think layer two on Bitcoin are one of the most interesting things happening in the whole crypto space right now. I would really appreciate a podcast on Bitcoin layer two. 
It would be interesting to hear about the pros and cons and the different approaches (technical implementation) and the risks associated with it.

The gold standard of Bitcoin L2’s is:
do something on L2 => (eventually) something is updated on L1 as a Push. 

Vanishingly few actually do this, and many will tell you this is impossible. Many of the drive and side chains will instead rely on a bridge mechanism to honour withdrawals on a pull basis.

I’m pumped about btc rollups, if only to encourage more natively supported cryptographic primitives on mainnet. 

Citrea is great for bringing the hype and attention, whilst not being too weird to be widely understood (looking at you DLC link). Even then it’s still only a humble optimistic roll up.
