I found this interview rather confusing and you can feel the tension between Peter and Paul. The LayerTwoLabs website links to some good videos though.

I think the 'marketing' of #drivechain is a little bit off. They don't clearly point out that it's all about a standardized way to create and run BTC sidechains. It's totally agnostic of how that sidechain is going to be implemented.

They talk too much about their modified zCash example, so people are mislead to believe it's about altcoins. #drivechain is all about ossification of layer 1 and creating Bitcoin-only scaling and innovation.
