How Is the ‘Empty Block’ Concept Relevant to Transaction Throughput?

The 'empty block' in PoA refers to the block template mined by PoW that initially contains no transactions. This separation of block creation (PoW) and transaction validation/inclusion (PoS) allows for potential optimizations.

The final block, after staker validation, will contain transactions. However, the initial PoW phase itself doesn't directly speed up transaction throughput, which is primarily limited by the PoS validation and network bandwidth.
