# Lox Lox is a reputation-based bridge distribution system that provides privacy protection to users and their social graph and is open to all users. Lox is written in rust and requires `cargo` to test. [Install Rust](https://www.rust-lang.org/tools/install). We used Rust version 1.56.0. Note that this implementation is coded such that the reachability certificate expires at 00:00 UTC. In reality, if the bucket is still reachable, a user could simply request a new reachability token if their request fails for this reason (a new certificate should be available prior to the outdated certificate expiring).
