This DHT implementation is aiming to provide a DHT for Codex with the following properties
* flexible secure transport usage with
2022-02-16 11:30:06 +01:00
* fast UDP based operation
2023-06-23 10:30:32 +02:00
* eventual fallback to TCP-based operation (maybe though libp2p)
* eventually support operation on top of libp2p
2022-02-16 11:30:06 +01:00
* 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
2023-06-23 10:30:32 +02:00
* eventually provide compatibility mode with the above specs

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