Previous version was very conservative about adding nodes to the routing table, requiring a full request/response message exchange initiated by us. Here we also add the node as 'seen' if the whoareyou/handshake exchange was successful. This significantly speeds up bootstreap from 0 Signed-off-by: Csaba Kiraly <csaba.kiraly@gmail.com>
A DHT implementation for Dagger
](https://codecov.io/gh/status-im/nim-libp2p-dht)
This DHT implementation is aiming to provide a DHT for Dagger with the following properties
- flexible transport usage with
- fast UDP based operation
- fallback to TCP-based operation (maybe though libp2p)
- 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
- provide compatibility mode with the above specs
Current implementation is based on nim-eth's Discovery v5 implementation. Base files were copied from nim-eth@779d767b024175a51cf74c79ec7513301ebe2f46
