Could you build this?
No Formally proving the consistency of Zermelo-Fraenkel set theory in axiom-free Lean is an extraordinary theoretical logic undertaking (and fundamentally intersects with Gödel's Second Incompleteness Theorem) requiring deep expertise in mathematical logic and interactive theorem proving.
What it would actually take: Requires deep specialized knowledge in mathematical logic, model theory, and Lean 4 formalization. One must construct a formal model of ZF within the base type theory of Lean (Calculus of Inductive Constructions) and mechanize thousands of lines of rigorous proofs demonstrating that each ZF axiom holds within the constructed model.
