Vitalik expands on his L2 critique
Ethereum co-founder Vitalik Buterin has followed up on his recent comments about Layer 2 blockchains, offering a sharper and more explicit critique of the current L2 landscape.
Rather than walking back his position, Vitalik clarified that his concern is not about scaling itself, but about a loss of imagination in Ethereum infrastructure design. In his view, too many projects are repeating the same architectural patterns without adding meaningful new capabilities.
Copy-paste EVM chains as an infrastructure dead end
Vitalik drew a direct analogy between today’s L2 ecosystem and past governance trends in DeFi.
He compared launching “yet another EVM chain with an optimistic bridge and a one-week withdrawal delay” to repeatedly forking Compound for governance purposes. Both approaches, he argued, reflect comfort and habit rather than innovation.
According to Vitalik, this pattern has led Ethereum infrastructure into a conceptual dead end, where new chains exist largely to capture liquidity rather than to expand what blockchains can actually do.
More L1s are not the answer
Vitalik was even more blunt about standalone EVM Layer 1 chains.
He stated that Ethereum does not need more copy-paste L1s, emphasizing that the base layer is already scaling and will provide significant EVM blockspace in the coming years. While Ethereum will not offer infinite capacity, it will be sufficient for most applications.
Specialized use cases, such as AI workloads, may still require lower latency or higher throughput than even a scaled Ethereum L1 can provide. But this does not justify launching generic EVM chains with minimal differentiation.
Innovation must come first, not branding
A central theme of Vitalik’s follow-up is that projects should build something genuinely new.
He pointed to examples such as privacy-focused systems, app-specific execution environments, ultra-low-latency designs, and architectures optimized for specific workloads. His list was intentionally incomplete, reflecting his belief that innovation should not be constrained to a narrow set of accepted designs.
The core requirement is differentiation. If a project does not meaningfully expand the design space, it should reconsider whether it needs its own chain at all.
When app chains actually make sense
Vitalik also offered a more nuanced take on app chains.
In some cases, he argued, tightly Ethereum-connected app chains are not only valid but desirable. He cited prediction markets as an example, where market creation and settlement could occur on Ethereum L1, while high-frequency trading executes on a rollup or L2 system that directly reads Ethereum state.
In such architectures, the connection to Ethereum is not cosmetic. It is foundational, enabling composability and shared security in ways that bridges cannot replicate.
Institutional L2s and algorithmic transparency
At the other end of the spectrum, Vitalik described a different category of systems he considers reasonable: institutional or semi-centralized chains that publish cryptographic proofs of their state transitions on-chain.
These systems are not Ethereum, not credibly neutral, and not fully trustless. Operators can still change rules or governance. However, they can deliver verifiable algorithmic transparency, allowing users to audit how decisions are made in areas such as government registries, social platforms, or regulated financial infrastructure.
While these systems should not be marketed as Ethereum scaling, Vitalik sees them as philosophically aligned with Ethereum’s broader goal of increasing trust minimization.
Vibes must match substance
One of the strongest points in Vitalik’s clarification is his insistence on honesty in positioning.
Projects should not claim deep Ethereum alignment if their technical connection is shallow. Conversely, systems that genuinely depend on Ethereum for security, settlement, or composability should embrace that identity clearly.
Public narratives, according to Vitalik, must reflect technical reality. Marketing should not compensate for architectural shortcuts.
BTCUSA commentary: the end of generic L2 narratives
From a BTCUSA perspective, this clarification reinforces a broader conclusion.
The era of generic L2 narratives is ending. Ethereum does not need more chains that exist primarily to capture value or replicate existing designs. What it needs are systems that either extend Ethereum in a meaningful way or openly pursue different goals without pretending to be something they are not.
Vitalik’s message is not anti-L2. It is pro-honesty, pro-specialization, and pro-innovation.
Conclusion
Vitalik Buterin’s follow-up makes his position unmistakably clear.
Ethereum scaling is not about cloning EVM environments or launching loosely connected chains. It is about building architectures that add real value, maintain honest connections to Ethereum where relevant, and expand the boundaries of what blockchain systems can do.
The next phase of Ethereum infrastructure will be defined less by labels like L1, L2, or app chain, and more by whether projects truly bring something new to the table.
