Yea, I mean the ETH zkRollups are super centralized but to some extent that’s a consequence of these things being hard to build so they need an “escape valve” in practice. There’s not a lot of motivation to remove that but I assume it’ll get removed eventually…. just may be a while.
I do think it’s somewhat informative that ETH only built *rollups*, which certainly don’t have a huge scalability multiple themselves (doubly so for payments, though it’s important to note ETH is trying to scale computation, not payments).
