Vitalik Buterin Says Ethereum Must Stay Both Usable and Decentralised

TLDR

• Buterin warns Ethereum must remain decentralised while becoming usable on a global scale
• 2025 saw upgrades like increased gas limits, zkEVM performance and more node reliability
• Ethereum’s goal remains to be a neutral infrastructure for finance, identity and governance
• Buterin introduces the “walkaway test” to measure application decentralisation

Ethereum co-founder Vitalik Buterin used his New Year message to urge the community to stay focused on the project’s founding goals. He said Ethereum must continue to grow as a reliable, decentralised, and censorship-resistant system, not just as a faster blockchain.

He acknowledged several major technical advancements in 2025, including improved node software and the development of zkEVMs. But he also made it clear that these improvements are not the destination. The real goal, he said, is for Ethereum to become a true “world computer,” a platform for neutral and reliable applications that do not depend on any single authority or service provider.

2025 Marked by Performance Gains Across Ethereum’s Core

Buterin noted several improvements in Ethereum’s technical foundation over the past year. These included an increase in gas limits, a higher number of data blobs, and growing maturity in zero-knowledge Ethereum Virtual Machines (zkEVMs).

“These developments allow Ethereum to scale better while remaining decentralised,” he wrote. Ethereum also made strides in PeerDAS, a data availability system that works with zkEVMs. These advancements contribute to Ethereum’s aim to become more efficient without losing decentralisation.

Node software quality also improved, making it easier for individuals to run their own nodes. This supports Ethereum’s vision of distributed infrastructure, rather than reliance on centralised services or corporate actors.

A Warning Against Chasing Trends and Centralisation

Vitalik Buterin urged the community to avoid “the quest of winning the next meta,” referring to trends like tokenized dollars or political memecoins. He also warned against artificial strategies to fill blockspace simply to promote Ethereum’s economic model.

He stressed that these approaches distract from the network’s real purpose. “We’re building applications that run without fraud, censorship or third-party interference,” he said. These applications, he explained, must function even if their original developers are no longer involved.

Buterin introduced what he called the “walkaway test,” the idea that a truly decentralised application should keep working even if its creators disappear. He contrasted this with current internet models that depend heavily on subscription services or centralised infrastructure.

A Call to Build Truly Decentralised Applications

Buterin explained that Ethereum must be both scalable and decentralised. That means improvements must happen not only at the base blockchain level, but also in the tools and applications built on top.

He gave an example: if Cloudflare, a centralised web service provider, were to go offline or be hacked, Ethereum-based apps should still run without interruption. “Users should not even notice,” he said. This level of resilience, according to Buterin, should apply to all applications, from finance to identity and governance. They must function independently of any company, political party, or ideology.

The Ethereum community continues to support Buterin’s commitment to decentralisation. One user, @lex_node, posted:

This message echoes Buterin’s larger point: Ethereum’s true test lies not in performance alone, but in its ability to serve as a decentralised platform that outlasts trends, companies, and centralised gatekeepers.
