Buterin sets out Ethereum’s vision as a cryptographic world computer

Ethereum co-founder Vitalik Buterin has described a future in which the network combines blockchain consensus with advanced cryptography, privacy technology and computation carried out beyond the main chain. In a blog post published on September 27, he presented that direction as the emergence of a “cryptographic world computer”.

CryptoBriefing reports that Buterin’s argument is less a detailed product schedule than a statement of where Ethereum could be heading over the next decade. By 2030, he expects the network to differ sharply from the platform first proposed in the early 2010s. Its design could support adjustable levels of computation, reduce the demands placed on ordinary node operators and make privacy part of the protocol itself.

The proposed shift would extend beyond simply processing more transactions. It would change how Ethereum proves that activity is valid, how its data is distributed and how decentralized applications remain operational when their original creators are no longer involved.

Proofs at the centre of the design

A central element of Buterin’s plan is the use of zero-knowledge proof systems, particularly SNARKs and STARKs, within Ethereum’s base layer. These methods allow a party to demonstrate that a calculation was performed correctly without disclosing the information used to produce the result.

For Ethereum, that could provide a way to expand computation while preserving verifiability and improving privacy. Rather than requiring every participant to reproduce every underlying operation, the network could rely more heavily on compact cryptographic evidence that the work was completed properly.

Buterin’s architecture also includes an optimized form of proof-of-stake consensus, PeerDAS and multi-party block construction. PeerDAS is intended to spread the work of storing and supplying data among many nodes. That would avoid requiring every node to retain the entire data set while still supporting the network’s ability to check and access what it needs.

These elements point to a system in which Ethereum’s security remains rooted in decentralized consensus, while some computation and data responsibilities are handled through specialized cryptographic mechanisms and distributed infrastructure.

Hegota marks a turning point

The clearest near-term milestone in the proposal is the Hegota fork, which is planned for 2027. Buterin said it may be the last Ethereum upgrade that would look familiar to someone who knew the network as it existed around 2015.

After that point, he anticipates a deeper focus on recursive STARKs, formal verification, protection against quantum threats and more extensive use of zero-knowledge techniques at the protocol level. The suggestion is that Hegota would close one phase of Ethereum’s development before the network moves into a more cryptography-centered period.

The fork will therefore be an important test of whether the ideas in Buterin’s post can be turned into working software. CryptoBriefing describes it as the first major opportunity to judge whether the proposed direction can move beyond a high-level vision and into Ethereum’s production technology.

Ethereum has already taken steps that fit parts of this broader plan. During the past year, the network increased its gas limits, expanded blob capacity and advanced work on zkEVM technology. Together, those changes are intended to help Ethereum handle more activity at lower cost while keeping transactions and computation verifiable.

Decentralization remains the measure

Buterin’s argument does not treat technical performance as the only measure of progress. He warned that a network can become faster while losing the qualities that make it valuable if development abandons decentralization, resistance to censorship or permissionless access.

He also proposed a test for decentralized applications: would an application continue to work if its original developers vanished? If it would not, then its dependence on those developers would call its decentralization into question. The idea, which Buterin calls the “walkaway test”, shifts attention from how an application is marketed to whether users can rely on it without a permanent central operator.

That principle links Ethereum’s technical roadmap to its political and structural goals. Privacy tools, off-chain computation and more efficient proofs may improve scale, but they would not by themselves guarantee that control is broadly distributed.

The comparison with Ethereum’s 2022 transition from proof-of-work to proof-of-stake underscores the potential significance of the next stage. Buterin’s proposed cryptographic architecture would not simply add another feature to the existing network. It would reshape how Ethereum handles computation, privacy, data and participation, with the 2027 Hegota fork set to provide the first substantial indication of how much of that transformation can be delivered.
