Vitalik Buterin Claims Ethereum Has Solved the Trilemma

Ethereum’s Technological Breakthrough

Vitalik Buterin announced that through the advancements in ZK-EVMs and the implementation of PeerDAS on the mainnet, Ethereum has tackled the blockchain trilemma. This trilemma involves achieving a balance between bandwidth, consensus, and decentralization—qualities that were historically viewed as conflicting.

Buterin anticipates that by 2026, there will be greater gas limits for non-ZK-EVM transactions, with ZK-EVM nodes expected to become the leading method of block validation between 2027 and 2030. Moreover, efforts toward distributed block building will continue, addressing centralization risks and ensuring equitable access across geographic locations.

“These are not small enhancements; they are transforming Ethereum into a fundamentally different and more robust decentralized network,” Buterin stated.

Breaking Through Bandwidth Barriers

In his analysis, Buterin likened Ethereum's advancements to the trajectory of early peer-to-peer networks. For instance, BitTorrent, introduced in 2000, boasted substantial total bandwidth and decentralization but lacked effective consensus mechanisms. Conversely, Bitcoin, launched in 2009, achieved consensus and decentralization but suffered from limited bandwidth due to its reliance on replicated workloads rather than distributed systems.

Buterin remarked, “With the deployment of PeerDAS and ZK-EVMs, Ethereum has achieved the trifecta of decentralization, consensus, and high bandwidth.” PeerDAS is currently operational on the mainnet, and ZK-EVMs are confirmed to have reached production-quality performance, with the remaining focus on enhancing safety.

The development of this technology has been years in the making, beginning around 2020 with initial attempts at ZK-EVMs. Looking ahead, Buterin provided a rollout timeline, highlighting that 2026 will see significant increases in gas limits via Bandwidth Allocation Limits (BALs) and the introduction of Proposer-Builder Separation (PBS). The first ZK-EVM nodes are expected to emerge during this period.

From 2026 to 2028, Ethereum plans to implement notable changes, including gas repricings and moving execution payloads into data blobs. These modifications will pave the way for safely deploying the higher gas limits.

Towards Fair and Distributed Block Building

From 2027 to 2030, Ethereum is expected to initiate substantial gas limit increases as ZK-EVM validation becomes the network's main method for confirming blocks. Buterin described the concept of distributed block building as a "long-term ideal" that involves ensuring blocks are not solely generated in one location.

“Prior to achieving this ideal, we aim to make the authority in block building as distributed as feasible,” Buterin noted. Distribution can occur both within the protocol through expanded FOCIL implementations or externally via distributed builder marketplaces.

In a post dated January 1, Buterin showcased the advancements achieved by Ethereum in 2025, including heightened gas limits, increased blob counts, enhanced software quality for nodes, and milestones in ZK-EVM performance. He urged the community to stay focused on Ethereum's central mission: “To create the world computer that serves as a foundational infrastructure for a more free and open internet.”
