This is the first of two torspec proposals to help Tor work with Sepcial-Use TLDs, like the GNU Name system or NameCoin. The second part will be an anycast facility. - Jeff
Hi Jeff,
Thanks for working on this; Namecoin is definitely interested in this effort. I have one comment. SPV-based Namecoin clients will, under some circumstances, generate network traffic to other Namecoin P2P nodes containing names being looked up. To avoid linkability, stream isolation should be used so that different Namecoin lookups go over different Tor circuits if the lookups correspond to TCP streams that go over different Tor circuits. (Also, the choice of Namecoin nodes to peer with should be different for each identity.) Therefore, it seems to me that there should be a mechanism for Tor to provide stream isolation information to the naming systems that it calls, along with "new identity" commands.
The above issue doesn't affect full Namecoin clients, or SPV Namecoin clients that download the full unspent domain name set. I don't know enough about the GNU Name System to know how this issue affects it, if at all.
Thoughts on this?
Also, trivial spelling nitpick: "Namecoin" is typically spelled with a lowercase "c", like "Bitcoin".
Thanks again for working on this!
