European Research Network on Formal Proofs

If testing can reveal errors in computer programs, only formal verification can guarantee their absence. The highest Evaluation Assurance Levels of the Common Criteria for Information Technology Security Evaluation require automatically checked mathematical proofs of correctness. Proofs are also the basis of mathematics and many sciences, and thus are very important in education and research.

In many computer technologies, developers and users rely on standard languages and protocols for exchanging data and enabling tool interoperability: TCP/IP for network communication, HTML for web pages, etc. This is however not the case for formal proofs, which is a major bottleneck for their adoption by the industry. The main reason is that, currently, proof systems use mutually incompatible logical foundations. Fortunately, only small parts of the proofs developed in a system use features that are incompatible with other systems.

Europe is a leading actor in the area of formal proofs: about 65% of the proof systems of the world are developed in Europe, including the two mostly used proof assistants, Coq and Isabelle.

This action aims at boosting the interoperability and usability of proof systems and make formal proofs enter a new era. For the first time, it gathers all the developers and users of proof systems in Europe. To make the proofs exchangeable, they will express, in a common logical framework, the logical foundations of their systems and develop tools for inter-translation of the proofs developed in individual systems to and from this common logical framework.
