Please correct me if I am not enough in the weeds. Isn’t Taiko at least very close to that?
They got the ULTRA TX approach to offer that.
They got this bridge. (Source code here) Which is not the ideal solution. Especially with those fees.
Based Preconfirmations are live on taiko main.
Nethermind created Surge based on that for a more generic approach.
And soon ENS is going to run their testnet on it and we can give it a try in more practice across L2s.
As it seems there are quite a few ideas floating around, but it hasn’t really tried in practice.
Especially not the L1 part of it? But what do I know really? Just an observer, most of the time.
Seems to me it’s pretty close to being somewhat ready. Really looking forward to that one.
