Well, Catala is a new project that takes this adage perhaps a bit too literally, by applying formal methods -- a field increasingly seen as immediately adjacent to cryptography -- on the French tax code! Catala aims to provide a “domain-specific programming language designed for deriving correct-by-construction implementations from legislative texts.” -- what that means is that you’ll be able to describe the tax code in a programming language, and get a proven-correct processing of your tax returns in that same language, too!

This episode of Cryptography FM is not directly about cryptography. Instead we’ll be covering a highly related and definitely interesting tangent: can we use the same formal methods that have recently proven the security of protocols like Signal and TLS in order to formally verify our tax returns? And, more importantly, can today’s guest help me pay less taxes?!

Joining us today is doctoral student Denis Merigoux, to talk about Catala, and more.
