"Batch exits" are underexplored in the effort to scale bitcoin
L2s like Lightning and Ark both support "unilateral exits," and you can save space by exiting directly from one L2 into another, but you can save even *more* space by doing that in batches
Is anyone working on this?
Won't you need to collaborate with other participants in systems like Ark and Spark if you want to do a batch exit?
Probably, and I'd like to see more work into making that painless
E.g. what if you could sign an "exit psbt," post it somewhere, and go offline. Maybe other people who also want to exit could add inputs and outputs to your psbt, and if 10 people do so, a service provider broadcasts it
Yes. Batch exits are possible with payment pools.
