Ethereum’s updated roadmap adds native rollups, stronger privacy, and post-quantum scaling as advances in cryptography and AI reshape the network’s long-term technical priorities, according to co-founder Vitalik Buterin.
Summary
- Quantum security has moved higher in Ethereum’s priorities compared with its 2023 roadmap.
- New areas include native rollups, stronger privacy, and blob and gas futures.
- Ethereum may use specialized scaling mechanisms for transfers, trading, and privacy applications.
- STARKs and AI-assisted formal verification could support upgrades across all three protocol layers.
Ethereum (ETH) co-founder Vitalik Buterin compared the network’s 2023 roadmap with its current Strawmap in an Aug. 10 X post, identifying several technologies that have gained, lost, or changed priority over the past three years.
Buterin said the two plans retain substantial overlap, but the order and implementation of several goals have changed. Quantum security has moved closer to the front of the roadmap, while verifiable delay functions and some proposed Ethereum Virtual Machine improvements have received less attention.
Older technical designs have also been replaced as Ethereum researchers identified alternatives. Plans involving Verkle trees shifted toward a unified binary tree and later a PBT design, while state expiry evolved into a broader proposal for new state types.
The biggest difference, according to Buterin, comes from the areas that did not appear in the 2023 roadmap. These include native privacy, post-quantum scaling, simpler specifications for formal verification, markets for future blob and gas capacity, native rollups, and a wider range of possible replacements or modifications for the EVM.
Ethereum privacy and quantum security move forward
Native privacy is one of the clearest additions to Ethereum’s long-term direction. Buterin listed keyed nonces, recent roots, parts of FOCIL, lean privacy pools, and wormholes among the mechanisms now being explored.
Keyed nonces could make it harder for observers to connect a user’s transactions, while recent-root mechanisms may allow private applications to verify recent blockchain states without revealing a complete history. FOCIL, meanwhile, is intended to make transaction inclusion more resistant to censorship by block builders.
The changes build on Buterin’s three-step Ethereum privacy plan released in May. That proposal combined account abstraction with FOCIL, keyed nonces, and changes at the wallet and access layers to reduce metadata leaks.
Post-quantum scaling has also become a separate priority. Ethereum currently depends on cryptographic systems that could eventually become vulnerable if sufficiently powerful quantum computers emerge. Replacing them without sharply increasing signature sizes, verification costs, or network bandwidth presents an additional scaling problem.
The current roadmap considers LeanSPHINCS signatures, signature aggregation, and “zkzk frames” as potential parts of the solution. Crypto.news previously reported that an Ethereum researcher demonstrated account-level post-quantum protection at an estimated cost of $0.07 per account, showing that wallet-level preparation may begin before a full protocol upgrade.
Ethereum’s Strawmap is not a finalized schedule. It is a coordination document covering proposed upgrades through 2029, with individual changes still requiring research, testing, and agreement among developers before they can reach the network.
Native rollups enter Ethereum’s design space
Native rollups were not included in the 2023 roadmap because zero-knowledge proof systems were not mature enough for developers to seriously consider integrating them into Ethereum’s base protocol, Buterin said.
Rollups currently operate as separate layer-2 systems. They process transactions outside Ethereum’s main execution layer and submit proofs or transaction data to the base network. Each rollup generally maintains its own contracts, proof system, upgrade controls, and security assumptions.
A native rollup would move part of that verification process into Ethereum itself. The base protocol could provide a standardized mechanism for checking state transitions, potentially reducing the amount of custom infrastructure each rollup must maintain.
Such a change could simplify the relationship between Ethereum and its layer-2 networks, though the exact design remains unsettled. Developers would still need to decide what functions should become native, how different virtual machines would be supported, and whether protocol-level verification could avoid creating new complexity.
The proposal arrives as Ethereum’s broader scaling approach changes. Buterin said the network is moving away from trying to scale every type of activity through one general mechanism. Instead, developers may build highly scalable but more restricted systems for common use cases such as token transfers, decentralized exchange trades, and privacy protocols.
This approach could allow Ethereum to process specific high-volume activities more efficiently without requiring every node or application to support the same expanded execution environment.
Blob and gas futures are another addition that did not exist as a developed roadmap concept in 2023. Such markets could allow users or layer-2 networks to lock in future access to Ethereum’s data or execution capacity, reducing uncertainty over costs during periods of heavy demand.
AI could make Ethereum easier to verify
Ethereum’s updated roadmap also places more weight on simplifying the protocol specification so developers can formally verify its behavior.
Formal verification uses mathematical proofs to determine whether software follows its intended rules. Applying it to an entire blockchain protocol has historically required substantial time and specialist work, particularly when the protocol includes multiple clients, cryptographic systems, and interacting layers.
Buterin argued that advances in artificial intelligence are making large-scale verification more practical. He previously said AI-assisted formal verification could become the “final form” of software development, allowing developers to combine optimized code with machine-checkable evidence that it works correctly.
That work is closely tied to Ethereum’s use of STARK proofs. Recursive STARKs allow one proof to verify another, producing compact evidence for increasingly large batches of computation.
Buterin said the same underlying verification method could eventually operate across Ethereum’s execution, consensus, and data layers. However, using a common proof system throughout the protocol would make the security of its implementation especially important, increasing the need for formal verification and independent testing.
Ethereum’s virtual machine may also change as these systems develop. Buterin said zkzk frames could require the protocol to expose an instruction set other than the EVM, with leanISA and RISC-V among the possible candidates.
Under one potential model, the EVM could continue serving developers and existing applications while operating as an intermediate representation above a simpler underlying instruction set. Buterin cautioned that this part of the design remains too early even for inclusion in the current Strawmap.
Roadmap remains a long-term coordination plan
Buterin’s comparison provides additional detail on Ethereum’s proposed Lean rebuild, which seeks to make the protocol quantum-safe, private, censorship-resistant, and easier to verify over the coming years.
The direction could eventually affect U.S. wallet providers, exchanges, institutional stakers, and layer-2 operators that rely on Ethereum. However, the post announced no immediate software release, hard fork, or mandatory action for users.
Each major proposal must still move through Ethereum’s research and governance process. Native rollups, alternative instruction sets, and post-quantum signatures remain technical directions rather than confirmed features with fixed activation dates.
Ethereum (ETH) showed no clear positive reaction to the roadmap update. ETH traded near $1,875 at the time of writing, down about 2.6% over the previous 24 hours as the broader crypto market weakened.
The latest comparison nevertheless shows how Ethereum’s development priorities have widened since 2023. Scaling remains central, but privacy, quantum resistance, and verifiable protocol design now carry more weight in determining how the network could operate through the end of the decade.
