Vitalik urges Ethereum to refocus on world computer mission.

Ethereum’s Commitment to Its Original Vision

Vitalik Buterin has stated that Ethereum's upgrades in 2025 are only meaningful if the platform remains committed to its vision of being a "world computer." This vision comprises scalable, decentralized applications that can operate independently of any controlling entities.

Buterin highlighted that over the past year, the Ethereum network has become faster, more reliable, and better equipped to scale without compromising its decentralized characteristics. According to his post on X, these enhancements have reduced network bottlenecks, boosted capacity, and simplified the operation of its software.

He described 2025 as a pivotal year for Ethereum’s core infrastructure, emphasizing that improvements to performance, stability, and usability are essential for preparing the network for future growth. The goal of these improvements is to ensure Ethereum can manage increased demand while retaining the attributes that differentiate it from centralized platforms.

The co-founder of Ethereum also pointed out that lowering barriers to running nodes and maintaining network integrity is vital for keeping Ethereum open and resilient as its user base expands.

The Pitfalls of Short-Term Focus

Despite the advancements, Buterin remains cautious, stating that achieving technical milestones should not be the ultimate objective. He expressed concern that Ethereum may lose its focus if it pays too much attention to fleeting market trends aimed at increasing activity or attention.

Buterin urges that Ethereum must work actively towards its established goals, cautioning against the temptation to engage in the "next meta." He referenced trends like tokenized currencies, political meme coins, and efforts that primarily signal economic relevance rather than provide lasting utility. These movements may generate brief interest but fail to further Ethereum’s deeper mission.

Upholding the “World Computer” Concept

Buterin reiterated the importance of viewing the network as a “world computer,” a foundational idea that has guided Ethereum from its inception. This concept underscores the blockchain’s role as a neutral and shared platform capable of running applications without central authority intervention.

He stressed that such applications should function without being subject to fraud, censorship, or control by third parties, even if the original developers are no longer involved. The idea of the “walkaway test” was emphasized—systems must operate independently of their maintainers.

Additionally, Buterin highlighted resilience as a key aspect; in a truly decentralized environment, users should not suffer disruptions if major infrastructure services are compromised or go offline. No single entity should have the power to disrupt access or functionality for the entire network.

This model contrasts sharply with the current internet landscape, where many tools have turned into subscription-based services, effectively locking users into centralized systems. Ethereum aspires to reverse this trend by restoring user autonomy and ensuring long-term reliability.

Achieving Decentralization and Usability

To truly succeed, Buterin asserts that Ethereum must achieve dual goals: it must be usable on a global scale and remain genuinely decentralized. Compromising one for the other could detract from the network’s fundamental purpose.

Moreover, he noted that the challenges extend beyond the blockchain’s base layer. Many Ethereum applications rely on centralized infrastructure, such as hosted servers and proprietary interfaces, which conflict with the essence of decentralized protocols. Addressing this dependency is crucial to realizing Ethereum's promise.

Buterin mentioned that the tools necessary for advancing Ethereum towards its ideals now exist, thanks to the technical groundwork established over the past year. He explained that recent engineering efforts are crucial for positioning Ethereum as lasting infrastructure for essential services like finance, identity, governance, and more.

As Ethereum moves into its next phase of transitioning from upgrades to real-world application, it remains to be seen how well its principles withstand the pressures of scaling. Buterin is clear: the impending challenges will test the resilience and efficacy of Ethereum’s core values.
