ProofWala: A Framework for Multilingual Proof Data Synthesis and Theorem-Proving

arXiv:2502.04671v3 Announce Type: replace-cross Abstract: Neural approaches to theorem proving require robust infrastructure for interfacing with interactive theorem provers (ITPs), extracting structured proof data, and executing proof search at scale. However, existing tooling is often assistant-specific and oriented toward file-level execution, making repository-scale analysis and parallel experimentation challenging. We present ProofWala, a multilingual proof engineering framework built around \texttt{itp-interface}, a reusable library for programmatic interaction with ITPs. For Lean 4, we

Why this matters
Why now

The increasing sophistication and scale of neural approaches to theorem proving necessitate more robust and flexible tooling to manage complex proof data and experimentation.

Why it’s important

This framework could significantly accelerate the development and application of AI in formal verification and automated reasoning, impacting software reliability, cybersecurity, and mathematical discovery.

What changes

The ability to synthesize multilingual proof data and interface programmatically with interactive theorem provers at scale becomes more accessible and standardized beyond assistant-specific solutions.

Winners
  • · AI/ML researchers in formal methods
  • · Developers of interactive theorem provers
  • · Industries reliant on formal verification
  • · Computer science education
Losers
  • · Companies with proprietary, closed-source ITPs
  • · Manual proof engineers
Second-order effects
Direct

It becomes easier to train robust AI models for theorem proving across multiple prover systems and languages, leading to faster research cycles.

Second

The improved accessibility and interoperability of ITPs could lead to a broader adoption of formal methods in software development and critical systems, enhancing reliability.

Third

Automated theorem proving could reach a 'GPT moment' where complex mathematical proofs and formal verifications are generated and checked with minimal human intervention, accelerating scientific progress.
