Vitalik Buterin Says Ethereum Network Capable of Many Upgrades

Ethereum co-founder Vitalik Buterin has once again shown why the blockchain remains one of the most resilient networks. On February 20, 2026, Buterin responded to a suggestion about rebuilding Ethereum from scratch. 

He compared Ethereum’s 2022 shift from Proof-of-Work to Proof-of-Stake, The Merge, to swapping a jet engine while in flight. He added that Ethereum could safely undergo up to four more major overhauls, showing its strong design and flexibility.

Vitalik Buterin Highlights Ethereum’s Resilience

According to Vitalik Buterin, Ethereum does not need a full rebuild. Instead, he proposed a “cypherpunk principled non-ugly” bolt-on system. This approach focuses on keeping censorship resistance, improving zero-knowledge (ZK) prover efficiency, and maintaining a lean consensus mechanism. 

Furthermore, it allows the network to scale while remaining compatible with existing applications. In short, Buterin aims for steady, manageable upgrades rather than radical changes.

Proposed Ethereum Upgrades

Buterin outlined several upgrades that could make Ethereum faster, more private, and more efficient. These include restructuring the state tree, adopting Lean consensus protocols, integrating ZK-EVM verification, and overhauling the virtual machine (VM). Each change is designed to work with the current network rather than replace it entirely. Additionally, these upgrades could help developers build applications that run more smoothly and handle more users.

Community Considerations and Risks

Even with careful planning, risks remain. Some community members may disagree on which upgrades to prioritize or how quickly to implement them. However, Buterin’s approach emphasizes gradual adoption and clear communication. This strategy aims to avoid splits in the community while still moving Ethereum forward. By balancing innovation with caution, Vitalik Buterin hopes to maintain trust among developers, investors, and users.

Vitalik Buterin’s Vision for Ethereum

In conclusion, Vitalik Buterin’s vision shows that Ethereum can continue improving without drastic resets. By using “in-flight jet engine swaps” as a metaphor, he highlights that the blockchain can evolve while keeping its core principles intact. If executed successfully, these changes could increase Ethereum’s speed, privacy,
