Vitalik Buterin: Ethereum Layer 2s must redefine their role

Vitalik Buterin urges Ethereum Layer 2 networks to shift focus from scaling to unique features, as improvements in the mainnet reduce the need for L2s as core scalability solutions.

Vitalik Buterin has urged a fundamental reassessment of Ethereum's Layer 2 (L2) networks, arguing that their original role as primary scaling solutions is now outdated. He cites two main reasons: the slow progress of L2s toward full decentralization and interoperability, and significant improvements in Ethereum's Layer 1 (L1), such as reduced transaction fees and planned gas limit increases. According to Buterin, these advancements mean Ethereum no longer needs L2s to act as 'branded shards' or core network extensions. Instead, he recommends that L2s pivot toward offering unique features like faster transactions, enhanced privacy, or specialized applications. This perspective highlights a broader industry debate about the future value of L2s, as Ethereum's base layer becomes increasingly capable and efficient.
