How Does the Blank Block Structure Impact the Overall Block Size?

The blank block structure in the PoW phase has a minimal impact on the overall block size because it only contains the header information, which is small. The majority of the block size is determined during the PoS phase when the selected validators fill the block with transactions.

Therefore, PoA does not inherently lead to smaller or larger blocks compared to a pure PoS system; the transaction capacity is determined by the PoS validation rules.
