Vitalik Buterin’s Provocative Challenge: Should Layer-2 Networks Evolve Beyond Mere Scaling?

Ethereum's co-founder just lobbed a philosophical grenade into the crypto-engineering community. Vitalik Buterin is pushing developers to ask a tougher question: what if scaling was just the warm-up act?

The Scaling Plateau

For years, the rallying cry was simple: more transactions, lower fees, faster finality. Layer-2 rollups and sidechains delivered, slashing gas costs and unclogging the mainnet. But hitting throughput targets creates a new dilemma—what's the encore?

Buterin's vision hints at a paradigm shift. It's not about building faster highways, but designing entirely new types of vehicles and destinations. Think native privacy features baked into the protocol, not bolted on. Imagine L2s that specialize in real-world asset settlement or become ultra-secure hubs for decentralized social graphs.

The finance bros chasing the next 100x memecoin pump might miss the point entirely—but then again, they usually do. This isn't about shaving another microsecond off a swap; it's about redefining what a blockchain can be.

The path forward is murky. Does specialization fracture liquidity? Can these networks maintain Ethereum's core security guarantees? One thing's clear: the era of one-dimensional scaling is over. The next battle for L2 supremacy won't be won on transactions-per-second alone, but on vision.

Layer-2 leaders offer mixed reactions

Leaders at prominent layer-2 projects responded to the statement. Most agreed that rollups need to do more than just offer cheaper transactions, but they disagreed on whether scaling should still be a key priority.

Karl Floersch, who helped start the Optimism Foundation, said on X that he welcomes the challenge of creating a flexible L2 system covering “the full spectrum of decentralization.” He also noted several problems that need fixing – long withdrawal times, missing production-ready Stage 2 proofs, and weak tools for apps that work across different chains.

“Stage 2 isn’t production-ready,” Floersch wrote. Current proofs aren’t secure enough to protect major bridges, he explained. He backed Buterin’s recent idea about adding native ethereum precompile for rollups to make trustless verification easier to use.

Arbitrum defends continued focus on scaling

Steven Goldfeder from Offchain Labs, which builds Arbitrum, took a stronger position in a detailed X thread. He said that while the rollup model has evolved, scaling still matters for L2s.

Goldfeder made it clear that Arbitrum wasn’t created as “a service to Ethereum.” The team chose Ethereum because it offers strong security and low-cost settlement, which makes large rollups possible. He pushed back on the idea that an upgraded Ethereum mainnet could match the volume L2 networks currently handle. He pointed to times when Arbitrum and Base each processed over 1,000 transactions per second while Ethereum handled fewer.

Companies might build separate layer-1 blockchains instead of using Ethereum if they think the network opposes rollups, he warned.

Jesse Pollak, who runs Base, wrote on X that improvements to Ethereum’s main LAYER help “the entire ecosystem.” He agreed that L2s need to offer more than just “Ethereum but cheaper.”

Pollak said Base has focused on bringing in new users and developers while moving toward Stage 2 decentralization. Features like better applications, account abstraction, and privacy tools match the direction Buterin outlined, he added.

Eli Ben-Sasson, head of StarkWare, which creates the Starknet rollup that doesn’t use EVM, gave a short but pointed reply on X: “Say Starknet without saying Starknet.”

His comment hinted that some zero-knowledge L2s already fit the specialized role Buterin described.

The discussion shows Ethereum’s development path is shifting as the main network gains new capabilities and layer-2 platforms figure out their future roles beyond simple scaling.
