Vitalik Buterin describes Ethereum’s future as a “cryptographic world computer” combining blockchain infrastructure with advanced cryptography. Planned changes include FOCIL, recursive STARKs
Vitalik Buterin says Ethereum is moving beyond its original blockchain design toward what he calls a “cryptographic world computer.” In his latest description, Buterin outlines changes planned after the Hegota fork, including zero-knowledge proofs, optimized consensus, formal verification, state management, and stronger privacy.
Buterin said Ethereum still retains core blockchain features linked to Bitcoin’s original design. However, its technology has changed substantially since Ethereum launched. Today’s network supports general-purpose computation, proof of stake, zero-knowledge applications, and Layer 2 networks.

Notably, Buterin said verification could shift from downloading and re-executing blocks. Instead, users could rely on PeerDAS sampling and SNARK verification.
Consensus would also move toward a more optimized proof-of-stake system. Meanwhile, block construction could involve multiple participants rather than one producer.
According to Buterin, future Ethereum could provide stronger censorship resistance through FOCIL. He also expects transaction finality to improve, with slots lasting roughly four to eight seconds. Execution costs would depend more on how applications organize computation.
Buterin said developers could pay less when work uses dependencies supporting parallel processing or pruning. He expects information about ordering and non-commutative state changes to remain onchain. Other computation could be aggregated before entering a final block.
Decentralized infrastructure could also process data and computation across participants. Buterin said modern cryptography addresses an older verification problem that limited this approach. Earlier systems relied on committees, which created setup costs, latency, and failure risks.
Buterin identified Hegota, planned for next year, as Ethereum’s likely last conventional fork. Afterward, he expects recursive STARKs, automated formal verification, optimized consensus, and quantum-safe development.
He also discussed obfuscation as a longer-term possibility. He said viable obfuscation could support encrypted computation involving many participants.
However, Buterin said Ethereum still faces challenges with efficient zero-knowledge proofs and large-scale state management. The architecture would combine blockchains, cryptographic verification, privacy tools, and decentralized off-chain components.
