Right, thanks. And I hope my question does not sound too critical. I was just genuinely curious why JS was used.

I think JS is fine for small to mid-sized tasks, prototyping and testing ideas. However, for real DNS servers, used by a lot of clients, I believe C, C++, Go or Rust would be an absolute requirement.

The JS implemention is a fork of bcoin, the JS Bitcoin full node and production backend.

It binds to libunbound but you are right that you would want a lower level language for it to be more scalable. There is a rust implemention work in progress here: https://github.com/UrkelLabs/rsd

There is also a C light client here: https://github.com/handshake-org/hnsd

For the consensus, there are C bindings for the cryptography and a workerpool that really speeds things up.

It could also be possible to dump the Handshake zone into a zone file and serve from behind unbound.

This is separate from the DNS resolver being written in JS, but the team behind Handshake also created bcoin, which is the only javascript fullnode (and non-core fullnode IIRC) that has mined a Bitcoin block.
