Ethereum co-founder Vitalik Buterin has outlined a long-term plan for the network to evolve beyond its current blockchain design into what he calls a “cryptographic world computer” by 2030.
In his September 27 essay, Buterin described an Ethereum that combines blockchain consensus with cryptographic proofs, data sampling, privacy technology, and decentralized computing outside the main chain. The goal is to let Ethereum handle more computation without requiring every participant to repeat the same work.
Buterin said the change would become more pronounced after Hegotá, the Ethereum upgrade planned for 2027. He described Hegotá as likely to be the network’s last “normal” fork before recursive STARKs, automated formal verification, more optimized consensus, and quantum-resistant cryptography become central to Ethereum’s development.
Ethereum Could Move From Recomputing to Verifying
One of the biggest changes in Buterin’s vision concerns how Ethereum verifies transactions. Today, full nodes download blockchain data and execute transactions themselves to check that the network followed its rules.
Multiple computers repeat much of the same work, which helps maintain security but also limits how much additional capacity Ethereum gets from adding more computers.
Buterin’s proposed model would rely more heavily on cryptographic proofs. Instead of every computer repeating a calculation, one computer or group could perform the work and produce a proof showing that the result is correct.
Other participants could then verify the proof without repeating the entire calculation. This could allow different computers to handle different tasks at the same time while Ethereum continues to check the results. Buterin said this approach was difficult to achieve in the past because the technology needed to verify distributed computation was not mature enough.
SNARKs and STARKs Become More Important
Zero-knowledge proof systems are central to the proposed architecture. Buterin’s comparison of Ethereum’s development describes a move from downloading and re-executing blockchain activity toward sampling data and verifying SNARKs.
This could reduce the amount of work required from individual nodes while preserving strong verification guarantees.
The longer-term roadmap also places recursive STARKs at the center of Ethereum’s development after Hegotá. These systems can combine multiple proofs into smaller proofs, allowing large amounts of computation to be represented and checked more efficiently.
The approach could also help Ethereum prepare for larger cryptographic requirements as the network moves toward quantum-resistant security.
Hegotá Could Mark a New Phase for Ethereum
Hegotá is planned for 2027 and currently sits after the Glamsterdam upgrade on Ethereum’s roadmap.
The upgrade already has FOCIL and Frame Transactions scheduled. FOCIL is designed to distribute transaction-inclusion authority among multiple validators, while Frame Transactions can give accounts more flexibility over transaction authorization and support features such as sponsored gas and alternative signature systems.
Buterin views Hegotá as a dividing line between Ethereum’s current architecture and the technology expected to follow.
After Hegotá, he expects upgrades to increasingly focus on recursive STARKs, automated formal verification, optimized consensus, and quantum-resistant cryptography.
Privacy Could Become a Core Part of Ethereum
The vision also includes changes to how Ethereum handles privacy. Buterin pointed out that users can reveal information even when their transactions themselves are private. For example, checking a wallet balance through an external server can reveal which addresses a user is interested in.
Future Ethereum infrastructure could use cryptographic techniques to hide more of this information, including payment details, balance requests, and account authorization data.
His essay also discusses the possibility of encrypted computation and stronger privacy systems further in the future, although some of these technologies remain research topics rather than confirmed upgrades.
Ethereum Could Process More Work Outside the Main Chain
The “cryptographic world computer” concept would not require Ethereum to handle all computation on its base layer.
Instead, Ethereum could record and order key information while decentralized networks handle other computations and provide cryptographic proofs for verification.
This could let different computers process tasks in parallel, making decentralization useful for performance as well as security.
| Ethereum 2030 Vision | Proposed Direction |
| Verification | Data sampling and cryptographic proof verification |
| Computation | More parallel and distributed processing |
| Consensus | More optimized proof-of-stake |
| Block construction | Multiple participants |
| Privacy | More use of zero-knowledge and network privacy tools |
| Scaling | More computation handled outside the main execution path |
| Security | Quantum-resistant cryptography |
Faster Finality and Lighter Network Requirements
Buterin’s 2030 comparison also points toward faster transaction confirmation.
The long-term target includes four- to eight-second slots and finality in roughly eight to 32 seconds, compared with Ethereum’s current longer finality process. These figures remain targets rather than confirmed upgrade specifications.
The proposed changes could also reduce the hardware and storage requirements for users who want to independently verify Ethereum.
Instead of requiring every participant to process the full history and repeat all transaction execution, more of that work could be represented through proofs and distributed data systems.
What Comes Next
Ethereum’s immediate milestone remains the Glamsterdam upgrade, followed by Hegotá in 2027. The longer-term changes described by Buterin will require years of development, testing, and protocol changes.
The biggest technical challenges include making zero-knowledge proofs cheaper and safer, coordinating parallel access to Ethereum’s state, and building systems that can distribute computation without weakening security.
Buterin’s vision therefore describes a direction for Ethereum rather than a completed upgrade plan. If the proposed technologies are developed successfully, Ethereum could rely less on repeated computation and more on cryptographic proofs to verify work performed across a distributed network.
What This Means for You: Ethereum is being developed toward a system where users and nodes may need to do less repeated computation while relying more on cryptographic proofs to verify activity. The changes are still being developed, with Hegotá planned for 2027 and many of the larger 2030 goals remaining part of Ethereum’s long-term roadmap.
