Certainly, we can verify that the L2 transactions were correctly executed, by re-execute the posted L2 transactions batch. But the L1 Contract should check the L2 transactions batch, not by re-execution (because it's the essence of rollups). I suppose proof includes some hash value of the L2 transactions batch, and L1 verifier contract can verify the posted L2 transactions batch by checking if the hash value of it corresponds to the proof's data.

What you suppose may not be currently supported, unless you’re looking for a hypothetical answer.

Do you mean, present implementations of L1 verifier contract do not check correspondence of transactions batch and proof's data? I would like to know the true concept of rollups method, but it might be under investigation.
