I ran across this video about the Rust programming language during a U.S. House Committee on Financial Services hearing, and crypto-currency . I'm not a Rust programmer (yet), but as a short background, Rust has some features that maintains boundaries that preserve large-system integrity. The Rust programming language is intended to be a language for highly concurrent and highly safe systems. Rust is syntactically similar to C++ (an old competitor), but it provides increased speed and better memory safety. The compiler is free and open-source. "Why was the Rust language chosen? Do you believe it's mature enough to handle the security challenges?" https://www.c-span.org/video/?c4808083/rust-language-chosen
