Tor Prop279 Provider for Namecoin

ncprop279 acts as a bridge between Tor Prop279 clients and Namecoin; it can be used for Namecoin naming in Tor. Unlike dns-prop279, it does not use the DNS wire protocol. This reduces attack surface and binary size, but prevents delegation from Namecoin to DNS via NS/DS records.

Usage

You need StemNS or TorNS in order to use ncprop279. You also need a Namecoin lookup client such as Namecoin Core, ConsensusJ-Namecoin, or Electrum-NMC. Your StemNS/TorNS services configuration might look like this:

_service_to_command = {
    "bit.onion": ['/path/to/ncprop279'],
    "bit": ['/path/to/ncprop279'],
}

ncprop279 can be configured by arguments on the command line (see ncprop279 -help) or by the same arguments listed in a configuration file. An example configuration file is provided in ncprop279.conf in this repository, uncomment and edit any desired lines. Note that the [ncprop279] section header is required. This configuration file will not be used automatically. To specify command line arguments directly or give a path to the configuration file, append to the list in the map mentioned above:

"bit.onion": ['/path/to/ncprop279', '-conf=/path/to/ncprop279.conf']

Security Notes

  • ncprop279 hasn't been carefully checked for proxy leaks.
  • Using ncprop279 will make you stand out from other Tor users.
  • Stream isolation for streams opened by applications (e.g. Tor Browser) should work fine.
  • Stream isolation metadata is passed through to the Namecoin lookup client, so any network traffic produced as a result of your lookups (e.g. traffic between Electrum-NMC and ElectrumX) will be stream-isolated.
  • Lookups are cached; the cache is stream-isolated.
  • This whole thing is highly experimental! Please test it and give feedback, but don't rely on it behaving correctly.
