Ethereum co-founder Vitalik Buterin has updated his 2023 roadmap, moving quantum safety and privacy higher among the network’s priorities. His latest comparison also removes or replaces several earlier plans, while adding native rollups, blob and gas futures, new state types, and broader execution options beyond the Ethereum Virtual Machine.
Buterin said some roadmap items were reshuffled, including higher priority for quantum safety. Meanwhile, VDFs and several EVM improvements have been deprioritized. Other plans also changed through newer technical designs.
Verkle trees gave way to unified binary trees and PBT, while state expiry was replaced by new state types. Notably, privacy now receives first-class attention in Ethereum’s updated plans. Buterin listed keyed nonces, recent roots, parts of FOCIL, lean privacy pools and wormholes.
The roadmap also adds post-quantum scaling through leanSPHINCS signatures and zkzk frames. Additionally, blob and gas futures now appear among Ethereum’s planned infrastructure.
Native rollups also entered the roadmap after advances in SNARK technology. Buterin said the technology was not mature enough for that approach in 2023.
Buterin also outlined a broader future for Ethereum’s execution layer. He said zkzk frames could lead the protocol toward exposing an instruction set beyond the EVM. LeanISA and RISC-V currently rank among the leading candidates.
Buterin described both as simpler, newer and more efficient than the EVM. He also raised the possibility of making the EVM an intermediate representation above another instruction set. However, he said deeper exploration remains too early for the current strawmap.
New state types also represent a different scaling approach, according to Buterin. The designs focus on specialized mechanisms rather than maximizing every type of Ethereum activity.
Buterin identified STARKs and AI-assisted formal verification as common themes across the updated roadmap. Recursive STARKs appear across multiple Ethereum protocol layers. One verification primitive could serve the execution, consensus and data layers.
Buterin said formal verification becomes necessary for safely deploying such shared components. He also linked broader formal verification efforts to modern AI tools. The updated roadmap therefore places greater emphasis on mathematical code verification.
Buterin said Ethereum’s long-term goals include quantum safety, stronger privacy, security, censorship resistance and greater scalability. He also described a future Ethereum architecture that remains lean.
