The Rollup-Centric Roadmap is Obsolete
Ethereum co-founder Vitalik Buterin has signaled the end of the “rollup-centric” scaling era, arguing that the original thesis for Layer 2 networks is no longer valid. In a blog post published Tuesday, Buterin noted that the Ethereum mainnet’s scalability upgrades, specifically the Pectra and Fusaka hard forks, have successfully driven average Layer 1 (L1) transaction fees down to $0.44, eroding the primary economic moat of Layer 2 competitors.
“The original vision of L2s and their role in Ethereum no longer makes sense,” Buterin wrote, highlighting that the cost distinction between L1 and L2 execution has largely vanished. Market data confirms the shift: average Ethereum transaction fees touched a low of $0.22 this week, a level not seen since the pre-DeFi era. The collapse in fees challenges the valuation models of major rollups like Arbitrum (ARB) and Optimism (OP), which rely on capturing the spread between L2 execution and L1 settlement costs.
“If you create an EVM that processes 10,000 transactions per second, but its connection to L1 is achieved through a multi-signature bridge, then you are not scaling Ethereum.”, Vitalik Buterin
‘Stage 1 or Bust’
Buterin’s critique extends beyond economics to security. He reiterated his “Stage 1 or bust” standard, observing that by early 2026, the vast majority of rollups remain in “Stage 0” (centralized training wheels) with single-sequencer setups and limited fraud proof capabilities. According to the post, regulatory pressures and technical stagnation have incentivized teams to maintain centralized control, effectively turning them into “branded shards” rather than decentralized scaling solutions.
The Pivot to Privacy and Performance
The directive for L2s is now to pivot or perish. Buterin outlined a new mandate for survival: Layer 2s must offer features the base layer cannot, such as sub-millisecond confirmation times, privacy preservation (zk-privacy), or application-specific environments for AI and gaming. This aligns with a recent outlook from 21Shares, which predicted a “harsh consolidation” for general-purpose rollups that fail to differentiate beyond cheap block space.
Market Reaction: The commentary sent shockwaves through the L2 sector. Governance tokens for major rollups faced immediate sell pressure as traders repriced the long-term revenue potential of execution layers in a low-fee L1 environment. Meanwhile, Ethereum (ETH) hovered near support at $2,120, as the market digests the deflationary impact of reduced fee burn.
