Ethereum Enters A New Era As ZK-EVMs And PeerDAS Reach Production Milestones

Ethereum is entering what its creator describes as a fundamentally new phase of existence.

In a detailed reflection on the network’s trajectory, Ethereum co-founder Vitalik Buterin said the combination of production-grade ZK-EVMs and PeerDAS now live on mainnet is transforming Ethereum into a network that simultaneously delivers high bandwidth, decentralized consensus, and resilience at scale. In practical terms, Buterin argues this marks the first time a blockchain is breaking the long-standing “blockchain trilemma” not as theory, but as working infrastructure.

In a post shared on X, Vitalik explained that Ethereum is no longer making incremental upgrades. Instead, it is evolving into a new class of decentralized system, one that combines properties that previously existed only in isolation across different generations of peer-to-peer networks.

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…

From BitTorrent And Bitcoin To Ethereum

To illustrate why this moment matters, Vitalik framed Ethereum’s evolution through the lens of earlier p2p systems. BitTorrent, launched in 2000, achieved enormous global bandwidth and strong decentralization but lacked any form of consensus. Bitcoin, introduced in 2009, solved consensus and decentralization but sacrificed bandwidth, as every node replicated the same work rather than distributing it.

Ethereum, with PeerDAS deployed in 2025 and ZK-EVMs reaching alpha-stage production performance, is now combining all three properties: decentralization, consensus, and high bandwidth. According to Vitalik, this is not an abstract roadmap goal, it is already happening with live code. Data availability sampling via PeerDAS is running on Ethereum mainnet today, while ZK-EVMs have reached performance levels suitable for real-world production, with safety work being the final major milestone.

This marks the culmination of a journey that began over a decade ago. ZK-EVM research itself dates back to around 2020, and the progress since then has accelerated rapidly. What once appeared experimental is now transitioning into the backbone of Ethereum’s future validation model.

Breaking The Blockchain Trilemma In Practice

Vitalik emphasized that the blockchain trilemma, balancing scalability, decentralization, and security, has often been “solved” only on paper. Ethereum’s current position is different. PeerDAS allows Ethereum to scale data availability without forcing every node to download everything, while ZK-EVMs allow computation to be verified succinctly rather than re-executed everywhere.

Together, these technologies shift Ethereum from a network constrained by replication into one capable of safely distributing work. This unlocks a path toward much higher gas limits without sacrificing decentralization. Importantly, this shift is happening incrementally, with safety and robustness prioritized over speed.

Vitalik stressed that these are not minor upgrades. They represent Ethereum becoming a fundamentally more powerful decentralized network, one that can realistically serve as a base layer for global-scale applications rather than merely a settlement engine.

The Roadmap From 2026 To 2030

Looking ahead, Vitalik laid out a multi-year timeline for how this transformation unfolds. In 2026, Ethereum is expected to see large increases in gas limits that do not yet rely on ZK-EVMs, enabled by technologies such as BALs and ePBS. That same year, the first opportunities to run ZK-EVM nodes are expected to emerge, allowing parts of the network to begin validating blocks using zero-knowledge proofs.

Between 2026 and 2028, Ethereum will undergo deeper structural changes. These include gas repricing, adjustments to state structure, and moving execution payloads into blobs. These changes are not cosmetic; they are required to ensure that higher gas limits remain safe and that nodes can continue to operate efficiently without centralization pressure.

From 2027 to 2030, ZK-EVMs are expected to become the primary method for validating blocks on Ethereum. At that point, large further increases in gas limits become feasible, fundamentally expanding Ethereum’s throughput while preserving its decentralized nature.

Distributed Block Building As The Long-Term Ideal

A third pillar of Vitalik’s vision is distributed block building. While not immediately necessary, he described it as a long-term “holy grail” for Ethereum. The ideal future is one where a full block is never assembled in a single location, eliminating concentration of power and reducing the risk of censorship or manipulation.

Even before reaching that ideal, Ethereum aims to distribute meaningful authority in block construction as widely as possible. This could happen in-protocol, through expanded mechanisms like FOCIL, or out-of-protocol via distributed builder marketplaces. Either approach reduces the risk of centralized interference in transaction inclusion and improves geographic fairness across the network.

Vitalik noted that block building centralization is not just a technical concern; it is a geopolitical one. A network that routes transaction inclusion through a narrow set of actors is inherently more fragile. Distributed block building creates a healthier environment where no single region or entity can dominate real-time transaction flow.

Ethereum’s Mission Beyond Short-Term Narratives

Underlying all of these technical milestones is a broader philosophical point. Ethereum is not optimizing for short-term narratives or chasing whichever application trend dominates the current cycle. Instead, it is building toward its original mission: becoming a world computer that serves as core infrastructure for a more free and open internet.

Vitalik framed Ethereum as a rebellion against increasing centralization in everyday technology. Applications built on Ethereum are meant to survive censorship, developer disappearance, corporate collapse, and geopolitical shifts. They should continue working even if key infrastructure providers fail or are compromised.

Achieving that vision requires Ethereum to be both usable at scale and genuinely decentralized, not just at the blockchain layer, but also at the application layer. ZK-EVMs, PeerDAS, and distributed block building are not ends in themselves; they are tools to support that mission.

As Ethereum enters 2026, the network is no longer simply evolving. It is transitioning into a new category of decentralized infrastructure, one that, for the first time, combines high bandwidth, consensus, and decentralization in live, production systems. The next few years will determine how fully that vision is realized, but the foundation is now firmly in place.
