A DHT implementation for Codex

This DHT implementation is aiming to provide a DHT for Codex with the following properties

• flexible secure transport usage with
  • fast UDP based operation
  • eventual fallback to TCP-based operation (maybe though libp2p)
  • eventually support operation on top of libp2p
• flexible message encoding that plays well with the above transports
• provide node lookup, content storage/lookup, and provider storage/lookup operations
  • roughly follow the libp2p-dht specifications from https://github.com/libp2p/specs/tree/master/kad-dht
  • eventually provide compatibility mode with the above specs

Current implementation is based on nim-eth's Discovery v5 implementation.

Building

This repo is setup to use Nimble lockfiles. This requires Nimble 0.14+ which isn't installed by default when this was written. If nimble -v reports 0.13.x then you will need to install Nimble 0.14. Note that using Nimble 0.14 changes how Nimble behaves!

Nimble 0.14 can be install by:

nimble install nimble@0.14.2

After this you can setup your Nimble environment. Note that this will build the pinned version of Nim! The first run can take ~15 minutes.

nimble setup # creates a nimble.paths used for rest of Nimble commands
nimble testAll

You can also run tasks directly:

nim testAll
