Ethereum’s Layer 2 Solutions Could Outrun the Main Blockchain by 2030

This article explains Ethereum Layer 2 solutions and their role in improving scalability and reducing costs, covering key approaches like Optimistic Rollups, ZK-Rollups, State Channels, and Plasma. It highlights the Dencun upgrade’s introduction of blobs to lower data costs, outlines Ethereum’s broader scaling roadmap (Surge, Scourge, Purge, Splurge), and projects significant growth potential—possibly reaching a $1T L2 market cap by 2030—while cautioning about risks such as sequencer centralization, fragmentation, and token market saturation.
