Ethereum Can’t Scale Alone - Here’s How Rollups Are Changing the Network

The Ethereum ecosystem is undergoing a recalibration of its scaling thesis. The rollup-centric roadmap, formalized in 2020, operated under the assumption that Layer 1 (L1) would act as a court of last resort, while Layer 2 (L2) solutions would absorb the entirety of the transactional surplus. On-chain activity data and core protocol developments throughout 2025 and 2026 partially invalidate this assumption. The issue does not reside in the efficiency of rollups for compressing data, but rather in the market’s inability to value decentralized security and the accelerated scaling of native L1 throughput.

The most relevant indicator of this dysfunction is the divergence between User Operations per Second (UOPS) and Total Value Locked (TVL). Rollups currently process over 3,400 operations per second, surpassing the mainnet in volume. However, the aggregate TVL of the L2 ecosystem has declined to figures near $50 billion in the third quarter of 2026, representing a year-over-year contraction exceeding 13%.
