In brief
- Vitalik Buterin says Ethereum has elevated quantum security and privacy since its 2023 roadmap.
- Ethereum researchers are increasingly relying on STARKs and AI-assisted formal verification.
- The roadmap also includes native rollups and explores a future beyond the EVM.
Ethereum co-founder Vitalik Buterin says quantum resistance, privacy, and AI-assisted security have become greater priorities for Ethereum since he published his 2023 roadmap.
In a post on X on Monday, Buterin said he updated his 2023 roadmap to compare its original goals with Ethereum’s current “Strawmap”—a working outline of the network’s long-term technical priorities.
“What's most striking, however, is that some completely new things are in the strawmap that are not in this diagram, because they were not in the 2023 roadmap at all,” Buterin wrote. “These reflect changing priorities.”
Among those priorities are stronger privacy and scaling designed for a post-quantum world, alongside efforts to push the “lean-ification of the spec,” or simplify Ethereum’s technical specifications.
“A common theme in scaling, found in both state types and zkzk frames (both new ideas), is that instead of trying to maximally scale all Ethereum activity,” Buterin wrote. “We try to create specialized mechanisms that have more restrictive properties that make them more scaling-friendly, while supporting the heaviest loads incurred by users and applications today (eg. token transfers, swaps) and tomorrow (eg. privacy protocols).”
According to Buterin, advances in AI are making it practical to apply the technique more extensively to Ethereum.
Buterin said Ethereum is increasingly relying on STARKs, a cryptographic technology used to verify computations, and AI-assisted verification, to check that the protocol works as intended.
“This can only be safe with formal verification, which is itself only feasible with modern AI tools,” he wrote.
Buterin’s post comes as Ethereum has accelerated preparations for “Q-Day” and the potential threat posed by quantum computers.
In January, Buterin urged developers to adopt quantum-resistant cryptography before the threat becomes immediate, and the Ethereum Foundation formed a dedicated post-quantum team. In February, Buterin outlined a phased plan to replace four potentially vulnerable components of Ethereum’s cryptographic architecture.
In July, Buterin put quantum safety and privacy at the center of his proposed “Lean Ethereum” overhaul, which calls for replacing quantum-vulnerable cryptography with quantum-safe alternatives.
“Ethereum will be quantum-safe. Ethereum will put users' privacy first. Ethereum will be secure,” Buterin wrote. “Ethereum will be censorship-resistant. Ethereum will be highly performant and scalable while satisfying the above. And Ethereum will be Lean.”
