Layer Two Scaling Issues

Architecture

Layer Two scaling solutions fundamentally alter the blockchain’s architecture, introducing off-chain computation and data storage to alleviate congestion on the primary chain. These systems, such as rollups and sidechains, operate independently but periodically settle transactions back onto the main chain, inheriting its security properties. The design choices within these architectures—the consensus mechanism, data availability methods, and settlement frequency—directly impact their scalability and security trade-offs. Consequently, architectural vulnerabilities or inefficiencies can manifest as scaling bottlenecks or introduce new attack vectors.
