Wait, are events really stored on-chain? That seems odd.

I feel like option A makes the most sense, but I’m a bit confused about the side-chain concept mentioned in option B.

I practiced a question similar to this, and I think events are primarily for tracking state changes rather than just debugging exceptions.

I remember something about events being useful for logging, but I can't recall if they can be accessed by contracts or not.

I think events are definitely stored on-chain, but I'm not entirely sure how they relate to return values when calling other contracts.
