Ethereum co‑founder Vitalik Buterin has once again stirred discussion in the crypto world with a pointed critique of the current direction of Ethereum scaling projects. In a series of posts and comments, he argued that the ecosystem is becoming saturated with repetitive, minimally differentiated chains that do little to advance blockchain technology – and urged developers to pursue fundamentally new ideas instead of replicating existing ones.
What Buterin Actually Said
At the heart of Buterin’s message is a clear warning: “We don’t need more copy‑paste EVM chains.” This phrase has become shorthand in the community for his view that launching additional Ethereum Virtual Machine (EVM)‑compatible chains that largely mimic Ethereum’s functionality – and connect to it via simple bridges – contributes more to confusion and fragmentation than to genuine progress.
Buterin explained that many of these new chains follow the same template: an EVM‑compatible environment, often coupled with an optimistic bridge that can have long withdrawal times, yet they fail to offer meaningful technological differences from existing networks. He likened this pattern to the early days of decentralized finance (DeFi) when protocols were frequently forked with little value added – something that brought short‑term gains but ultimately slowed innovation.
“Make yet another EVM chain and add an optimistic bridge to Ethereum with a 1-week delay … that’s like forking Compound over and over again.” – Vitalik Buterin (as quoted in multiple posts)
Why Buterin Thinks This Matters
Buterin’s critique is grounded in how Ethereum’s original scaling vision has evolved. When Ethereum first pushed for Layer‑2 (L2) rollups and sidechains, the priority was simply more throughput and lower fees, often via EVM‑compatible environments. But the network base layer has since scaled substantially, and tools like zero‑knowledge (ZK) proofs and enhanced blockspace availability have reduced the urgency of the old model.
As a result, Buterin argues:
- Ethereum L1 is scaling itself – reducing the need for every new project to clone basic EVM execution.
- Copy‑paste chains fragment liquidity and ecosystem focus without solving new problems.
- Superficial bridges to Ethereum give a false sense of integration when technical depth is minimal.
What Buterin Wants Instead
Rather than more of the same, Buterin is urging developers to focus on genuinely innovative and differentiated blockchain designs – systems that expand what blockchains can do instead of just where they can run familiar code. Examples he and commentators have highlighted include:
- Privacy‑focussed architectures that protect user data by design.
- App‑specific execution environments that optimize performance for particular use cases (like gaming, AI, or identity).
- Ultra‑low latency systems for high‑performance applications.
- Truly deep integration with Ethereum L1, where essential functions (like settlement, accounts, or proofs) rely on Ethereum rather than just marketing claims.
In his view, innovation should expand capabilities, not just replicate existing ones. This means moving beyond convenience or familiarity toward building systems that address real technical challenges and offer novel benefits.
Not All Chains Are Dismissed
It’s important to note that Buterin isn’t rejecting all new projects – he simply wants them to be substantive. Chains and rollups that introduce meaningful advances – for example, new security models, privacy guarantees, or native support for emerging applications – can still play valuable roles in the ecosystem, especially if they maintain a credible technical relationship with Ethereum’s core.
Why This Matters for Ethereum’s Future
Buterin’s comments reflect a broader evolution in Ethereum’s story. What once was a simple scaling race – “more throughput for cheap transactions” – is now shifting toward deeper architectural questions: what can blockchains meaningfully do that they couldn’t before? These discussions are shaping not just technical roadmaps, but developer incentives, funding decisions, and ecosystem priorities.
Whether developers embrace this call to innovate or continue building incremental clones, this moment could be a turning point in where the Ethereum ecosystem heads next.
