Re: [tor-dev] [Discussion] 5 ^H 3 hops rendezvous circuit design

Note that Phantom allows both the service and the client to choose the number of hops under their respective control. I believe this applies in part to I2P as well. There is thus no force to accept any globally enforced maximum hopcount there. This concept may or not work for Tor. _

Hi all, Apologies for top-posting. I'm making a brief comment about general concerns in this design. Additional apologies if something already said obviates my comments. I have purposely not looked at most of the developments in HS design changes because they are _too_ interesting to me and I have

BTW, we might be able reduce number of hops to 4 or even 3 if entry guard is not required. Because entry guard is basically not negotiable. ___ tor-dev mailing list tor-dev@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-de
