So a gate using multiple selectors like `q_enabled * (1 - q_first) * meta.query_advice(column, Rotation::prev())` is not allowed? Where `q_enabled` is enabled on each usable row, and `q_first` only enabled...

Hey, thanks for looking into this. Seems like Arbitrum may have some problems with `mstore8`, otherwise not much changed. No idea why this would be. > There's also something here...

Haven't compared them, but they are pretty much the same so any difference in gas will be extremely small. The OpenZeppelin implementation is based on my code, they just saw...

Unfortunately because of the heavy limitations rust put on objects that want to implement `Copy`, this is a tricky one. `Expression`s are variable sized objects, built recursively, so not something...

We also only have partial support at this point. We do the basefee adjusting code in a smart contract so we don't have to implement it in a dedicated circuit,...

> Brecht, do you think 12 second is too short, what use cases demand "the L2 block building window deterministic for a longer time"? Mostly fast soft confirmations with an...

Makes sense I think! Couple of small questions: - Is the padding state still necessary now that empty bytecodes are supported? Seems like it would be possible to do the...

It is indeed not part of this PR, but if needed I think we can add support for that in another PR if others are interested. We will be handling...

Sure thing, can start working on this next week.
