Couldn't find any introduction to the project on the blog but the official repo has more info on the background for the project:<p>>Rust is more secure than C. Despite our efforts, it's all too simple to
mess up when using a language that does not enforce memory safety. We
estimate that at least half of our tracked security vulnerabilities would
have been impossible in Rust, and many of the others would have been very
unlikely.<p>>Arti is cleaner than our C tor implementation. Although we've tried to
develop C tor well, we've learned a lot since we started it back in 2002.
There are lots of places in the current C codebase where complicated
"spaghetti" relationships between different pieces of code make our software
needlessly hard to understand and improve.<p><a href="https://gitlab.torproject.org/tpo/core/arti" rel="nofollow">https://gitlab.torproject.org/tpo/core/arti</a>
