Ethereum Co-Founder Vitalik Buterin Says AI Could Speed Up ETH Roadmap While Warning of Security Risks
Vitalik Buterin, the co-creator of Ethereum, has revealed that artificial intelligence technology is pushing development timelines forward at an unprecedented pace.
Following through on a challenge issued in February, a developer leveraged AI capabilities to create a working prototype of Ethereum’s complete development roadmap extending to 2030—all within several weeks. Buterin described the achievement as “quite an impressive experiment” in a post shared on X during the weekend.
According to Buterin, AI is “massively accelerating coding” processes, and stakeholders “should be open to the possibility that the Ethereum roadmap will finish much faster than people expect.”
He further suggested the work could be delivered “at a much higher standard of security than people expect.”
Yet Buterin emphasized that the code produced through AI assistance almost definitely harbors serious bugs. He noted certain sections might represent “stub” implementations where the AI didn’t even pursue complete functionality.
“But six months ago, even this was far outside the realm of possibility,” Buterin remarked.
He proposed that development teams capture only fifty percent of the time advantages offered by AI, dedicating the remaining benefit toward strengthening security measures. This approach would involve creating additional test scenarios, implementing formal verification processes, and developing multiple independent implementations of every component.
Buterin expressed personal enthusiasm about the prospect that bug-free code, “long considered an idealistic delusion,” might become a realistic standard.
Ethereum’s State Tree and EVM Overhaul
On Sunday, Buterin released an extensive analysis of two fundamental architectural transformations he views as essential to Ethereum’s long-term evolution.
The first transformation involves migrating away from the existing hexary Keccak Merkle Patricia Tree toward a binary state tree structure outlined in EIP-7864. This enhancement proposal has remained in draft status since January 2025.
The binary tree architecture would generate Merkle branches that are four times more compact than current structures. Modifying the hash function could additionally boost proving efficiency anywhere from 3x to 100x.
Verkle Trees had been under consideration for a 2026 hard fork implementation, but emerging quantum computing vulnerabilities prompted renewed focus on binary tree solutions around the middle of 2024.
The second transformation entails substituting the EVM with RISC-V, an open-source instruction set architecture already adopted by most ZK proving systems. Buterin initially introduced this concept in April 2025.
Pushback and Next Steps
Research teams from Offchain Labs, the organization behind Arbitrum, released a counter-argument in November 2025 contending that WebAssembly represents a superior long-term alternative to RISC-V for Ethereum’s smart contract execution environment.
Buterin asserted that these two architectural changes collectively address more than 80% of Ethereum’s proving performance constraints, rendering both modifications “basically mandatory.”
Ethereum’s Glamsterdam upgrade is targeted for the first half of 2026, followed by the Hegota upgrade later in the same year. Core developers have yet to confirm the primary EIP for either network fork.
