Ethereum co-founder Vitalik Buterin mentioned that with the Ethereum Digital Machine (ZK-EVM) transitioning into manufacturing use, the community has successfully “solved” the blockchain trilemma of decentralization, consensus, and excessive bandwidth, arguing that the lacking parts at the moment are both dwell on the mainnet or inside attain.
In a publish revealed on X on January 3, Buterin framed the second round two technical developments. PeerDAS and ZK-EVM, that are at present dwell on the Ethereum mainnet, are in “alpha stage” with “manufacturing high quality efficiency” and “the remaining operations are secure,” he defined.
“This isn’t a minor enchancment; it’s basically reworking Ethereum into a brand new, extra highly effective decentralized community,” Buterin wrote. “To seek out out why, let’s have a look at the 2 predominant kinds of P2P networks.”
Buterin drew a distinction between early peer-to-peer methods that may scale throughput however lack consensus on shared state, and blockchains that obtain sturdy consensus however pay for it with restricted bandwidth. He pointed to BitTorrent as a decentralized distribution mannequin with out consensus, and Bitcoin as a decentralized and consensus mannequin that retains bandwidth low as a result of “the work is replicated fairly than ‘distributed’ within the sense that it’s break up.”
Ethereum will resolve the blockchain trilemma
Based on Buterin, Ethereum is getting into the third class. “Now with Ethereum, with PeerDAS (2025) and ZK-EVM (a part of the community anticipated to make use of it in 2026), we are able to obtain decentralization, consensus and excessive bandwidth,” he mentioned. “The trilemma has been solved via actual executable code, not paper. Half of them (Information Availability Sampling) are at present on mainnet and the opposite half (ZK-EVM) is at present manufacturing high quality by way of efficiency. Security stays.”
Buterin touted this because the fruits of a multi-year roadmap fairly than a sudden breakthrough. He described it as a “10-year journey,” pointing to early knowledge availability sampling research and noting that the ZK-EVM effort started round 2020. The crux of his argument is that whereas knowledge availability sampling adjustments what a decentralized community can securely publish and confirm at scale, ZK-EVM adjustments how nodes confirm their execution, shifting verification to proof-based verification because the expertise matures.
Buterin laid out a tough timeline for the way he expects the imaginative and prescient to unfold over the following 4 years. In 2026, he expects “large gasoline restrict will increase that don’t depend on ZKEVM” associated to BAL and ePBS, together with the primary alternative to run ZK-EVM nodes.
From 2026 to 2028, he foresees a sequence of adjustments, gasoline value changes, state restructuring, transferring execution payloads to blobs, and different steps geared toward making larger gasoline limits secure. He expects “gasoline limits to extend considerably additional” between 2027 and 2030, with ZK-EVM changing into “the first methodology of validating blocks on the community.”
He additionally flagged distributed block constructing, which he known as the “third piece” of the puzzle. He wrote that the long-term aim is “a world the place whole blocks are by no means organized in a single place,” however emphasised that “it gained’t be obligatory for a very long time.” Within the quick time period, the main focus will likely be on distributing “significant authority to construct blocks,” both via in-protocol mechanisms (he cites FOCIL extensions as the principle transaction channel) or via external-protocol methods comparable to a decentralized builder market.
For Buterin, block-building decentralization is not only an engineering desire, however a matter of threat and equity. He argued that this would cut back the probability of “centralized interference with the inclusion of real-time transactions” whereas creating “a greater setting for geographic equity.”
At press time, ETH was buying and selling at $3,164.
