At the same time, proofs are an integrated part of the formalism, allowing, via the + Curry Howard + isomorphism, a smooth interplay between + specification and reasoning: proofs are objects of the language, and + can be treated as normal data, naturally leading to a programming style + akin to proof-carrying-code, + where chunks of software + come equipped with proofs of (some of) their properties.

Matita is currently adopted in the European Union "Certified Complexity" Project + CerCo for the formal verification of a + complexity-preserving compiler from a large subset of C to a microcontroller + assembly of the kind traditionally used in embedded systems.
