If there's something I should have on my radar then please let > me know! Hi Damian! That's awesome, and good to know - I first wrote that text a few months ago (on the basis of David's comments in that ticket) and haven't revised it since, so I am heartened to see progress. However I am also not the best person to say what else will be needed, because that would probably be Donncha re: the future of OnionBalance for v3. At the moment in OnionBalance the v2 Introduction Points of the (predetermined) worker onions are passively scraped from the HSDir; the descriptors are parsed, the IPs are blended and re-combined and re-signed under the master onion key (eg: nytimes3xbfgragh) and then published back to the HSDirs, with the result that NewYorkTimes-browsing clients end up communicating with 1 of N possible "worker" daemons, thereby sharing the load. My understanding - and please jump in, if I am wrong - is that the synthesis of a v3 descriptor which blends the introduction points of several independent v3 "worker" Tor daemons will be a more complex affair than the existing process, because (?) the "worker" tor daemons will somehow have to be more actively involved - apparently they may have to sign the v3 Introduction Points themselves, though I am not sure how that will work for a blended descriptor? Multiple/distinct signatures, perhaps? The last opportunity I had to speak with anyone (re: this) was more than 1 year ago, so I am rusty, and I apologise if I have gotten some details wrong. So: OnionBalance relies heavily upon Stem ( https://github.com/DonnchaC/onionbalance/tree/develop/onionbalance) and I am not qualified to say what, if any, additional v3 Stem features will be useful or outstanding to support the descriptor-blending that is needed for loadbalanced configurations. But OnionBalance for v3 will certainly be necessary. :-) -a -- http://dropsafe.crypticide.com/aboutalecm
