Vitalik Buterin: Hegotá May Be Ethereum's Last 'Normal' Fork Before Major Redesign

Ethereum co-founder Vitalik Buterin said the upcoming Hegotá hard fork, planned for 2027, will likely be the final upgrade whose features and architecture remain recognizable to anyone familiar with Ethereum circa 2015. In a post on Sunday, Buterin framed Hegotá as a turning point, after which Ethereum's development will pivot toward more advanced cryptographic technologies, including recursive STARKs, automated formal verification, optimized consensus mechanisms, and quantum-safe cryptography.

Buterin pointed to PeerDAS, a data availability sampling protocol that allows nodes to verify transactions by examining portions of data rather than downloading full blocks, as the catalyst for Ethereum's evolution into a "cryptographic world computer." This transition moves Ethereum beyond a model where nodes simply re-execute every transaction, toward an architecture that combines onchain settlement with offchain computation, cryptographic verification, and privacy-preserving components. Applications built on this new model could offload complex processes to offchain environments while relying on the base layer to verify results, settle transactions, and preserve shared onchain state.

The proposal sparked debate within the Ethereum community about how much computation and state should ultimately migrate offchain. Ethereum researcher Barnabé Monnot argued that while offchain execution with onchain proofs can reduce network load and enable lighter nodes, a true world computer must still maintain critical application records directly onchain. Doing so, Monnot said, would allow users to monitor activity and interact with applications without depending on external servers or intermediaries. Pseudonymous commentator Cryptographic added that the architecture could expand what DeFi protocols can achieve, enabling tasks such as collateral analysis, liquidation routing, and lending matching to occur offchain while Ethereum verifies compliance and finalizes settlement.

The discussion is part of Buterin's broader "Lean Ethereum" initiative, which he has described as a roadmap for simplifying the network's core architecture while enhancing security and scalability. As Ethereum approaches its Hegotá upgrade, the community is now weighing how to balance decentralization with performance, ensuring that the base layer remains a trustless foundation even as more complex workloads shift to offchain environments.
