> The long-term vision would use PeerDAS, SNARK verification and optimized proof-of-stake, while Ethereum’s protocol plan targets quantum resistance by Dec. 2029.

Ethereum co-founder Vitalik Buterin outlined a long-term vision for the network as a cryptographic computing system by 2030, with deeper verification and post-quantum security built into its core design.

The proposal is a technical direction rather than a finalized upgrade timetable. It would use PeerDAS data sampling and SNARK verification so nodes would not need to download and re-execute every computation themselves.

Buterin described Ethereum’s development as a progression from proof-of-work to proof-of-stake and then toward a more optimized proof-of-stake system. The model would also support multiple forms of multi-party block construction.

“The Ethereum of tomorrow will have computation with a tunable dial between extreme scale and full generality, multiple forms of multi-participant block construction, a highly optimized form of proof of stake, and zero-knowledge proofs baked in playing key roles at the base layer,” Buterin wrote.

The design could affect how developers build applications. Future applications may allow computation to be processed in parallel or removed before it becomes part of a final block, changing how work is organized across the network.

Development after the Lean phase would include recursive STARKs, automated formal verification, optimized consensus algorithms and quantum-safe technology. Buterin summarized that stage by writing, “Everything after that involves recursive STARKs, automated formal verification, highly optimized consensus algorithms, and making it all quantum-safe.”

Ethereum’s protocol plan targets quantum resistance across the execution, consensus and data layers by Dec. 2029. It also calls for preparation against a potential “Q-day” as early as 2030, although the roadmap’s milestone names and ordering may change.

The quantum-vulnerable components include BLS validator signatures, KZG data-availability commitments, ECDSA account signatures and some application-layer zero-knowledge proof systems. These cryptographic tools support validator operations, data verification, account control and privacy-related applications across Ethereum.

The 2029 security target and Buterin’s 2030 vision describe related but separate planning horizons. Neither establishes a binding governance decision or complete schedule for future upgrades.
