Description

Similar to torrent's DHT solution, required features:

  • Find peer to specified site file (to allow sites to add optionally download files)
  • Ipv6 and tor address support for peers
  • It should work using on Tor (TCP only, maybe UDP on clearnet)
  • No other library dependency if possible
  • Store peer ips to allow work without bootstrap server

Maybe its requred to separate the DHT from Peer Exchange

Please comment if you have other ideas/suggestions.

Research direction
Examine the existing peer exchange implementation in ZeroNet (likely in src/Peer/Peer.py and related files). Study Kademlia DHT protocol, particularly the kademlia library. Consider how to integrate DHT without external dependencies, possibly implementing a minimal Kademlia variant. Review Tor network constraints (TCP only) and plan for IPv6 support. Look at how bitTorrent DHT works for inspiration. Start by prototyping a separate DHT module that can be tested independently.
