Vitalik Buterin Advocates Vibe-Coding Critical Software in Lean Theorem Prover

X/Twitter·high signal

Ethereum co-founder Vitalik Buterin posted on X (1,436 likes, 163K views) endorsing vibe-coding for critical software — with a twist: use the Lean formal verification language so AI-generated code is mathematically proven correct. Buterin cited the Verified-zkEVM ArkLib project and zkSecurity's 'The Final Form of Software Development' post as examples. The implication is profound for builders: developers could let AI write implementation while the theorem prover guarantees correctness, eliminating the need for manual code review of low-level details.
