ZeroTier version 2 is being built in Rust, with the main reasons being safety (it's a network protocol!), easier cross platform compilation, easier dependency management, and an all around better language than C++. It should help us greatly boost developer velocity while also be much safer from a security point of view.
That will also make it more attractive to other developers using Rust who want to embed the SDK. Speaking of which, I've emailed ZeroTier a couple of times now about licensing the SDK (the first email was last week), and haven't yet heard back.
