How Do ‘Layer 2’ Solutions Address PoW Scalability Issues?

Layer 2 solutions, such as Lightning Network or rollups, process transactions off the main (Layer 1) PoW chain, bundling them together before submitting a single proof back to Layer 1. This significantly increases transaction throughput and reduces fees by offloading the bulk of the computational work from the main chain.
