Ethereum (ETH) Co-Founder Vitalik Buterin: AI Can Accelerate Development While Posing Security Challenges
Vitalik Buterin, the co-founder of Ethereum, has revealed that artificial intelligence technology is pushing network development forward at an unprecedented pace.
In a recent development, a programmer accepted a challenge posed by Buterin in February and leveraged AI tools to build a working prototype of Ethereum’s complete roadmap extending to 2030—all within mere weeks. Buterin described the achievement as “quite an impressive experiment” in a weekend post on X.
According to Buterin, AI technology 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 network could achieve completion “at a much higher standard of security than people expect.”
Nevertheless, Buterin emphasized that the AI-produced code likely harbors serious bugs. He noted certain sections might be “stub” implementations where the AI avoided creating complete functionality.
“But six months ago, even this was far outside the realm of possibility,” Buterin remarked.
He advised development teams to invest only half their AI-derived time savings into acceleration while dedicating the remainder to security enhancements. This approach involves creating additional test scenarios, implementing formal verification protocols, and developing multiple independent implementations of each module.
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 substantial architectural modifications he considers essential for Ethereum’s evolution.
The initial modification involves transitioning away from the existing hexary Keccak Merkle Patricia Tree toward a binary state tree framework outlined in EIP-7864. This enhancement proposal has remained in draft status since January 2025.
The binary architecture would generate Merkle branches that are four times more compact than current implementations. Additionally, modifying the hash function could boost proving efficiency anywhere from 3x to 100x.
Verkle Trees were initially considered for a 2026 hard fork implementation, though quantum computing risks prompted a pivot toward binary tree solutions around the middle of 2024.
The secondary modification entails substituting the EVM with RISC-V, an open-source instruction set that most zero-knowledge provers currently utilize. 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 infrastructure.
Buterin stated these two architectural modifications combined address more than 80% of Ethereum’s proving performance constraints, rendering both “basically mandatory.”
Ethereum’s Glamsterdam upgrade is slated for the first half of 2026, with Hegota expected to launch later during the same year. Development teams have yet to confirm the primary EIP for either hard fork.
