UDP packets get lost easily. We can't just remove nodes from the routing table at first loss, as it can create issues in small networks and in cases of temporary connection failures. Signed-off-by: Csaba Kiraly <csaba.kiraly@gmail.com>
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
