This article was first published on The Bit Journal. Ethereum co-founder Vitalik Buterin has warned that the blockchain network is approaching a defining crossroads, urging the community to choose between chasing short-term speculative trends or recommitting to Ethereum’s original vision as a neutral, global “world computer.” His comments put a fresh focus on the changing Ethereum roadmap and on the way in which the network is heading as it steps into its next development stage.
Ethereum Roadmap Gains Clarity After Breakthrough
In two elaborate posts on X, Buterin speculated about the year 2025 as a year when Ethereum would see major technical advances, and warned that he was worried about what he termed an escalating addiction to the next meta. He stated that current cycles are fuelled by political memecoins, tokenized dollars, and attempts to artificially stimulate on-chain activity, which distract developers and users from long-term objectives as defined in the Ethereum roadmap.
Buterin says that Ethereum has just passed a technical turning point: the long-standing scalability trilemma of the blockchain industry has finally been successfully solved. The trilemma, which asserts that at any given time, decentralized networks could optimize two out of three properties decentralization, security, and scalability, had been established over a decade.
PeerDAS and ZK-EVMs Transform Ethereum Scalability
According to Butterin, significant upgrades were being deployed in 2025, such as the mainnet deployment of PeerDAS and the maturity of zero-knowledge Ethereum Virtual Machines (ZK-EVMs) have changed that equation fundamentally. These advancements, which are at the core of the Ethereum roadmap, are evidence that the trade-offs are no longer hypothetical but issues which have been overcome in live running code. Buterin wrote:
“Ethereum with PeerDAS (2025) and ZK-EVMs (expect small portions of the network using it in 2026), we get: decentralized, consensus and high bandwidth The trilemma has been solved.”
He explained the accomplishment as the result of a research effort spanning over 10 years starting with initial studies on data availability and erasure coding.
Now that ZKEVMs are at alpha stage (production-quality performance, remaining work is safety) and PeerDAS is live on mainnet, it's time to talk more about what this combination means for Ethereum.
These are not minor improvements; they are shifting Ethereum into being a…

Buterin Frames Ethereum as Internet Rebellion
In a bid to describe the scale of the change, Buterin likened the development of Ethereum to two previous peer-to-peer systems. He mentioned that BitTorrent, which was released in 2000, reached enormous bandwidth and decentralized but had no consensus and that Bitcoin was released in 2009, offering decentralized consensus at the expense of low throughput. Ethereum 2025, he argued, is basically a combination of these two models, an important milestone which now officially is a part of the Ethereum roadmap.
When describing these technical victories, Buterin pointed out that these victories are not the ultimate goal. Instead, he positioned them as the base of what he referred to as a rebellion in regard to the current subscription-based, centralized internet. He denounced the current digital services that tie users into a platform that is run by intermediaries and exposes them to censorship, outages or platform failures. He wrote:
“Ethereum is the rebellion against this.”
Welcome to 2026! Milady is back.
Ethereum did a lot in 2025: gas limits increased, blob count increased, node software quality improved, zkEVMs blasted through their performance milestones, and with zkEVMs and PeerDAS ethereum made its largest step toward being a fundamentally…

Ethereum Sets Timeline for ZK-EVM Adoption
The core of this vision is the so-called walkaway test which Buterin applies to test the ability of applications to remain operating without fraud, censorship, or other third-party oversight even when the original developers vanish. He claimed that the ability to reach this standard should continue to be a major priority along the Ethereum roadmap.
In the future, Buterin has designed a multi-year roadmap of Ethereum but the near term is up to 2025. In 2026, the network will introduce large gas limit increments with modifications like BALs and ePBS, and the first user opportunities to run ZK-EVM nodes. In 2026 and 2028, additional upgrades will change the network state and transfer the execution payloads into data blobs to enhance efficiency. ZK-EVMs will become the dominant way to verify a block by 2027 to 2030, allowing capacity greater increases.
Ethereum Roadmap Targets Decentralized Block Construction
In addition to scaling, in the Ethereum roadmap Buterin proposed distributed block building in the long term to lower centralized influence and enhance geographical equity in transaction inclusion.
In the end, the message of Buterin was more of a technical report and philosophical challenge. As the engineering barriers have mostly been eliminated, he contended that the future of Ethereum will be whether the community uses the Ethereum roadmap to create long-lasting, decentralized infrastructure or remains focused on the economic signalling of the next market cycle.
Conclusion
Ultimately, Buterin framed Ethereum’s future as a matter of collective choice rather than technical limitation. As the scalability trilemma was mostly settled, he contended that the network was under a new challenge: to develop a resilient, decentralized infrastructure that can satisfy the vision of the world computer, or stay focused on the short-term market narratives.
