Vitalik Buterin: Ethereum ZK-EVM Will Solve the Blockchain Trilemma When It Reaches Production Level
TLDR
ZK-EVMs achieved production-level performance in alpha with PeerDAS today on the Ethereum mainnet.
Ethereum now combines high bandwidth, consensus and decentralization, solving the blockchain trilemma.
The gas limit increase will start in 2026, with ZK-EVMs becoming the main block proof in 2027 to 2030.
Decentralized block building remains a long-term goal to reduce centralization and improve geographic equity.
ZK-EVMs have achieved production-level performance in alpha, a turning point for Ethereum's scalability roadmap.
Ethereum founder Vitalik Buterin announced that the combination of zero-knowledge Ethereum virtual machines and PerdaS on the mainnet marks a fundamental change for the network.
This development addresses the long-standing blockchain trilemma of achieving decentralization, consensus, and high bandwidth simultaneously. The event comes after a decade of research and development.
Breaking the Blockchain Trilemma Using Live Technology
Buterin explained how Ethereum has evolved from previous peer-to-peer network models. BitTorrent offered high bandwidth and decentralization but lacked consensus mechanisms.
Bitcoin offers decentralization and consensus, but suffers from limited bandwidth due to its multiplicative rather than distributed structure. Ethereum now combines all three elements with the integration of PeerDAS and ZK-EVM.
The announcement emphasized that this achievement was in live running code rather than a theoretical proposal. PeerDAS currently runs on the Ethereum mainnet, providing data availability sampling functionality.
ZK-EVMs have reached production quality in terms of performance, the rest of the work is focused on security improvements. Both components work together to allow the network to process large amounts of data while maintaining security and decentralization.
This technical discovery completes a journey that began around 2015 with a preliminary data availability sample study. ZK-EVM development efforts have started around 2020.
Buterin shared the first GitHub commit with data availability and code scrapping to show the extended timeline.
The convergence of these technologies now enables Ethereum to support massively high yields.
Roadmap to 2030 and distributed construction goals
The implementation schedule will be extended over the next four years with specific milestones. In the year In 2026, Ethereum will implement large gas limit increases from ZK-EVM requirements via BALs and ePBS.
The network will see initial opportunities to run ZK-EVM nodes. This phase focuses on expanding capacity while maintaining network stability.
Between 2026 and 2028, developers will introduce gas surveying and state structure improvements. Execution charges will be transferred to Blobs along with other technical adjustments.
These changes are intended to make higher gas limits operationally safer. The slow approach allows the network to adapt over time rather than through disruptive updates.
From 2027 to 2030, ZK-EVMs will be the primary block verification method across Ethereum. This transition allows for an additional gas limit increase. Buterin presented the construction of the distributed block as a long-term goal.
The goal is to prevent a complete ban on the constitution in one place, reducing the risks of centralized intervention. This can happen through expanded or distributed developer marketplaces in the Protocol, such as FOCIL, by improving geographic equity to include marketing.
