Vitalik Buterin Maps Ethereum's Transformation Beyond 2027

Vitalik Buterin believes that Hegota, the Ethereum fork planned for 2027, could be the last update based on technologies familiar to developers from 2015. The network will not stop evolving afterward. Its future transformations will rely more on cryptographic proofs, parallel execution, and formal verification.

Hegota would open a new era for Ethereum

In an essay published on September 27, Vitalik Buterin presents Ethereum as a system that gradually surpasses its role as a distributed ledger. “It really is no longer just a blockchain”, he also stated on X, as he detailed his vision of the network by 2030.

The Ethereum co-founder considers Hegota to be the probable last “normal” fork. This term describes an update whose components remain recognizable to a developer who was present at the network’s launch. It therefore does not mean that Hegota will be the ultimate evolution of the protocol.

This distinction helps summarize the main announced changes :

• Hegota remains scheduled for 2027 according to the roadmap cited by Buterin ;
• The next updates should use recursive STARK proofs ;
• Automated formal verification will take a more important place ;
• The consensus must become more efficient and resist future quantum threats.

The final content of Hegota is not yet fully locked. The Ethereum Foundation established a process separating the selection of the main features called headliners and that of secondary improvements. Each proposal must be evaluated based on its utility, maturity, and technical risks.

Cryptographic proofs should replace repeated computations

Currently, computers that fully verify Ethereum reproduce the computations contained in transactions. This repetition strengthens security but limits gains when new machines join the network: multiple participants essentially perform the same work.

Buterin wishes to replace part of this mechanic with cryptographic proofs. A computer would perform a computation, then produce a short mathematical proof. Other participants could verify this proof without redoing the entire operation.

“At the time, this approach was not viable for a main reason: the missing ingredient was verification”, he writes about the early attempts to distribute work. The committees used in old models increased costs, delays, and failure risks. Zero-knowledge proofs must now fulfill this role more efficiently.

This architecture would allow several machines to process different tasks simultaneously. Ethereum would keep operations requiring a common order on its main layer, such as two transactions trying to spend the same funds.

Applications will need to better organize their computations

This evolution would also change how applications are built. A program grouping all its operations into a sequential transaction might become more costly than another capable of separating its computations into independent tasks.

Developers would thus be encouraged to aggregate signatures or proofs before submitting them in a block. Only state changes requiring precise sequencing would be directly handled by the blockchain. The rest could be executed off-chain, then cryptographically verified.

For Buterin, decentralization would then no longer be only a constraint accepted in the name of security. It would also allow storing more data and distributing computations among several participants. It could even enhance privacy by masking the origin of certain queries.

The vision for 2030 still faces several obstacles

Buterin envisions finality between eight and 32 seconds, lighter nodes, and better guarantees of transaction inclusion. Privacy would also cover indirectly revealed data when a wallet queries a server to check its balance. These objectives describe however a future architecture, not Ethereum’s current performance.

Several difficulties remain to be solved. Zero-knowledge proofs must become less costly and secure enough to be used on a large scale. The network must also coordinate parallel access to the large amounts of data stored by applications.

Buterin finally acknowledges a structural limit: “Ethereum itself will never have latency comparable to servers, but the infrastructure built around it could”. Hegota therefore will not mark the end of Ethereum forks, but the transition to a generation of updates much more cryptographic, experimental, and complex.
