Ethereum's Layer 2 (L2) networks are seeing a massive increase in transactions, up 90 times since 2021.

The shift to L2 platforms like Arbitrum and Optimism is crucial for Ethereum's future due to scaling issues and high fees on the main network.

L2 networks offer advantages such as faster transactions and lower fees, which are attractive to developers.

Vitalik Buterin's Ethereum roadmap emphasizes the importance of L2 networks and cross-rollup standards for ecosystem development.

Updates like single slot finality, cross-rollup standards, and deep cryptography show a dedication to improving efficiency, security, and privacy.

The growth in L2 networks is predicted to spur innovation in DeFi, NFTs, and other projects.
