You do realize that even if they would switch blockchains that would be many months of development effort, right? It would also require a slow migration of all nodes, with every SNO changing their setup to include new addresses for the new blockchain.
Also, I don’t want to switch coins and blockchains… so there’s that too. I’m probably not alone in that.
That’s not exactly a now solution anyway. And I think zkSync solves a lot of the same issues, but is much easier to quickly implement.
