Vitalik: AI-Assisted Formal Verification Could Be a Key Path to Enhancing Ethereum’s Security and Efficiency

Vitalik published an article titled “A Shallow Dive into Formal Verification,” introducing recent progress in applying formal verification to Ethereum’s cutting-edge research and development. The article states that developers can write code in Lean, EVM bytecode, or assembly language and verify its correctness via mathematically rigorous proofs that can be automatically checked—thereby improving both code efficiency and security. He notes that formal verification is especially suitable for complex yet well-defined-security systems such as STARKs, Byzantine Fault Tolerant (BFT) consensus, ZK-EVMs, and post-quantum signatures, and mentions related projects including Arklib, VCV-io, and evm-asm. The article also emphasizes that formal verification is not a panacea: it remains subject to limitations such as incorrect specification definitions, unverified code paths, hardware-level constraints, and side-channel attacks.
