Vitalik Buterin Says AI Could Speed Up Ethereum’s (ETH) Roadmap, But Warns of Security Risks
Ethereum’s co-founder Vitalik Buterin recently revealed that artificial intelligence technology is pushing development timelines forward at unprecedented rates.
In a remarkable demonstration of AI capabilities, a developer successfully completed a bet made with Buterin in February by using artificial intelligence to create a working prototype of Ethereum’s entire roadmap extending to 2030—all within several weeks. Buterin praised the achievement as “quite an impressive experiment” in a weekend post on X.
According to Buterin, AI is “massively accelerating coding” capabilities, and the community “should be open to the possibility that the Ethereum roadmap will finish much faster than people expect.”
He further suggested the roadmap could be delivered “at a much higher standard of security than people expect.”
Nevertheless, Buterin emphasized that the AI-produced code definitely harbors critical flaws. He noted certain sections may represent “stub” implementations where the AI only created placeholder code rather than complete solutions.
“But six months ago, even this was far outside the realm of possibility,” Buterin noted.
He advised development teams to invest only half of the time efficiency gains from AI tools, while dedicating the remaining benefits to strengthening security measures. This includes creating comprehensive test suites, conducting formal code verification, and developing redundant implementations of critical components.
Buterin expressed personal enthusiasm about the prospect that bug-free code, “long considered an idealistic delusion,” might become a realistic industry standard.
Major Infrastructure Overhauls for Ethereum’s State Tree and EVM
Over the weekend, Buterin also released an extensive analysis of two fundamental architectural transformations he considers essential for Ethereum’s evolution.
The initial change involves transitioning from the existing hexary Keccak Merkle Patricia Tree to a binary state tree architecture through EIP-7864. This enhancement proposal has been under development since January 2025.
The binary tree structure would generate Merkle branches approximately four times more compact than the current system. Additionally, updating the hash function could enhance proving efficiency by factors ranging from 3x to 100x.
Verkle Trees were originally under consideration for a 2026 hard fork, but growing concerns about quantum computing threats prompted a strategic pivot toward binary tree structures around the middle of 2024.
The second transformation entails replacing the EVM with RISC-V, an open-source instruction set architecture already utilized by most zero-knowledge provers. Buterin initially introduced this concept in April 2025.
Industry Response and Development Timeline
Scientists from Offchain Labs, the development team responsible for Arbitrum, issued a counterargument in November 2025 contending that WebAssembly represents a superior long-term alternative to RISC-V for Ethereum’s smart contract infrastructure.
Buterin emphasized that these two architectural modifications together resolve more than 80% of Ethereum’s proving performance constraints, making both changes “basically mandatory.”
Ethereum’s Glamsterdam upgrade is targeted for the first half of 2026, with the Hegota upgrade scheduled to follow during the latter portion of that year. Development teams have yet to confirm the primary EIP for either hard fork.
