Ethereum scaling, explained in layers

What scaling is trying to solve

Scaling discussions concern how a network can accommodate more activity. Throughput, costs and security assumptions all matter. A useful explanation should identify which problem a particular design addresses, rather than presenting speed alone as a complete evaluation.

Read the architecture

Ethereum documentation describes several scaling approaches. Layer 2 systems are part of that discussion. To understand a specific system, follow its own documentation and examine how it relates to Ethereum, including what happens when transactions are settled.

A more useful comparison

Compare systems using a stated task and date. Ask what the quoted fee includes and what assumptions the design makes. Describing something as a layer does not, by itself, tell a reader everything about its reliability or limitations.
