In our project coq-of-rust we translate programs written in Rust to equivalent programs in the language of the proof system Coq馃悡, which will later allow us to formally verify them. Both Coq and Rust have many unique features, and there are many differences between them, so in the process of translation we need to treat the case of each language construction separately. In this post, we discuss how we translate the most complicated one: traits.

Our primary goal at FormalLand馃尣 is to make Tezos the first crypto-currency with a formally verified implementation. With formal verification, thanks to mathematical methods, we can check that a program behaves as expected for all possible inputs. Formal verification goes beyond what testing can do, as testing can only handle a finite amount of cases. That is critical as cryptocurrencies hold a large amount of money (around $3B for Tezos today). The current result of our verification project is available on Formal verification is also key to allowing Tezos to evolve constantly in a safe and backward compatible manner.
