#Layer2

Ethereum co-founder Vitalik Buterin criticizes the proliferation of copycat L2 networks, arguing that scaling alone is no longer enough. What does this mean for blockchain's future?

In January 2026, Ethereum active addresses surpassed major layer-2 networks as lower fees revitalized on-chain activity on the mainnet.

Ethereum has increased its per-block data capacity, raising the blob target to 14 and the max limit to 21 to reduce Layer 2 fees and improve network scaling.
