I don't understand drivechains enough either.

But I have a simple question to all drivechain proponents.

Tell me one use-case that we need on #bitcoin and that we can't resolve by standard L2s which would justify the protocol change.

The discussion is cirlcing around miners incentives, potentially unknown risks to the protocol, etc. But I want to know what it brings that we actually need and want on bitcoin. Because I can't think of anything...

And if that is the case, then it really is just dangerous, meaningless messing with miners' incentives and potentially unwanted consequences to the protocol.

I heard from multiple sources that it could bring sidechain with great privacy. In my opinion this can be resolved on L2 or with combination of CoinJoin and L2. I don't see need for ultra private sidechain.

But I am waiting to get educated.
