Ethereum must meet ‘world computer’ test without losing decentralization

Vitalik Buterin says Ethereum’s 2025 upgrades only matter if the network doubles down on its “world computer” mission: scalable, truly decentralized, walkaway-proof apps.
Summary

• Buterin says 2025 brought major gains in speed, reliability, and node usability, laying groundwork for long-term Ethereum growth.
• He warns against chasing short-term metas like political meme coins or activity theater that dilute Ethereum’s core “world computer” mission.
• Ethereum must prove it can scale while staying decentralized across both base layer and apps, passing a “walkaway test” for censorship-resistant infra.

Ethereum co-founder Vitalik Buterin said the blockchain platform made significant technical progress in 2025 but cautioned that its long-term success depends on adhering to its original mission rather than pursuing short-term market trends.

Ethereum on the crypto push with Buterin leading the way

In a post shared Thursday on X, Buterin stated that Ethereum became faster, more reliable, and better able to scale while maintaining its decentralized foundations during the past year, according to the message. The improvements reduced bottlenecks, increased capacity, and simplified operation of the network’s underlying software, he said.

Buterin characterized 2025 as a year in which Ethereum’s core infrastructure matured. He stated that work focused on improving performance, stability, and usability was critical to preparing the network for long-term growth, according to the post. These efforts aimed to enable Ethereum to handle increased activity while preserving properties that distinguish it from centralized systems, he said.

The co-founder emphasized that lower barriers to running nodes and maintaining the network are important for keeping Ethereum open and resilient as usage expands, according to the message.

Despite the progress, Buterin stated that technical milestones are not the end goal. He warned that Ethereum risks losing focus if it concentrates too heavily on short-term trends designed to boost activity or market attention.

“Ethereum needs to do more to meet its own stated goals,” Buterin wrote, cautioning against efforts to “win the next meta.” He cited examples including tokenized dollars, political meme coins, and activity engineered primarily to signal economic relevance rather than deliver lasting utility. Such narratives may generate temporary momentum but do little to advance Ethereum’s deeper purpose, he stated.

Buterin returned to the concept of the network as a “world computer,” a vision that has shaped Ethereum since its inception. That concept centers on the blockchain as a neutral, shared platform where applications can run without reliance on centralized intermediaries, according to the post.

He stated that such applications should be capable of operating without fraud, censorship, or third-party control, even if their original developers disappear. Buterin highlighted the “walkaway test” as a key benchmark, meaning systems should continue functioning regardless of who maintains them, according to the message.

The co-founder also stressed the importance of resilience, stating that in a truly decentralized system, users should not be affected if major infrastructure providers go offline or are compromised. No single entity should be able to disrupt access or functionality for the broader network, he said.

Buterin contrasted that model with the modern internet, where many tools have become subscription-based services that lock users into centralized platforms. Ethereum represents an alternative by aiming to restore user autonomy and long-term reliability, he stated.

To succeed, Ethereum must satisfy two requirements simultaneously: it must be usable on a global scale and remain genuinely decentralized, Buterin said. Achieving one without the other would undermine the network’s purpose, according to the post.

The challenge extends beyond the blockchain’s base layer, he stated. Many applications built on Ethereum rely on centralized infrastructure such as hosted servers or proprietary interfaces despite using decentralized protocols. Addressing that dependency is essential to fulfilling Ethereum’s promise, Buterin said.

Buterin stated that tools now exist to advance Ethereum closer to its ideals, thanks to technical groundwork laid over the past year. The message served as an explanation of why recent engineering work matters: to position Ethereum as durable infrastructure for finance, identity, governance, and other foundational internet services, according to the post.

Whether Ethereum can meet those objectives will become clearer as the network’s next phase shifts from upgrades to real-world use, testing how its principles hold up under scale, Buterin said.
