Glad to hear this isn't dead. </div><div class="gmail_msg"><br class="gmail_msg"></div><div dir="ltr" class="gmail_msg">Anyone looking at deploying this should give a serious look at CONAME ( <a href="https://github.com/yahoo/coname" class="gmail_msg" target="_blank">https://github.com/yahoo/coname</a>.) as well, which was developed at yahoo/google as part of end-to-end and is in large part based on CONIKS. It's also written in go, was aimed at deployment on real cloud infrastructure with a distributed database backend, and offered different scalability trade offs that are far better suited to deployment at scale. I think there is also a javascript client *somewhere*. </div><div dir="ltr" class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">As I recall the rough difference was : Unlike CONIKS, where users had to check every version of the tree for consistency, dename/coname allowed users to merely check a counter attached to their key entry in the latest tree and see that it had not been incremented. Other dedicated verifiers were responsible for checking that counter values were correct over multiple version of the tree. This greatly reduced the load on both the server and the bandwidth requirements for clients. At any reasonable scale, having every user download log(n) elements in a tree every epoch seemed prohibitive, hence the design tweak.</div><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg"> The cost of this was it was much harder to completely hide the number of users added to the tree in a given epoch. Surprisingly, completely hiding such information was not a particularly pressing concern during development.<br class="gmail_msg"></div><div dir="ltr" class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">There was a thread on it with far mere details here <a href="https://moderncrypto.org/mail-archive/messaging/2015/001771.html" class="gmail_msg" target="_blank">https://moderncrypto.org/mail-archive/messaging/2015/001771.html</a>.</div></div><div dir="ltr" class="gmail_msg"><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">I didn't work on this project, I was just around during its development, so my description may be a bit off.</div></div></div><div dir="ltr" class="gmail_msg"><div dir="ltr" class="gmail_msg"><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_msg">Thanks, </div><div class="gmail_msg">Ian</div></div></div><div dir="ltr" class="gmail_msg"><div dir="ltr" class="gmail_msg"><div class="gmail_msg"><br class="gmail_msg"></div><div class="gmail_quote gmail_msg"><div dir="ltr" class="gmail_msg">On Mon, Dec 5, 2016 at 2:17 PM Marcela Melara <<a href="mailto:melara@cs.princeton.edu" class="gmail_msg" target="_blank">melara@cs.princeton.edu</a>> wrote:<br class="gmail_msg"></div><blockquote class="gmail_quote gmail_msg" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word" class="gmail_msg"><div style="line-height:1.38;margin-top:0pt;margin-bottom:0pt" class="gmail_msg"><font face="Arial" class="gmail_msg"><span style="font-size:15px" class="gmail_msg">Hi everyone,</span></font></div><div style="line-height:1.38;margin-top:0pt;margin-bottom:0pt" class="gmail_msg"><span style="font-size:14.666666666666666px;font-family:Arial;font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-alternates:normal;font-variant-east-asian:normal;vertical-align:baseline" class="gmail_msg"><br class="gmail_msg"></span></div><div style="line-height:1.38;margin-top:0pt;margin-bottom:0pt" class="gmail_msg"><span style="font-size:14.666666666666666px;font-family:Arial;font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-alternates:normal;font-variant-east-asian:normal;vertical-align:baseline" class="gmail_msg">We are happy to announce our first release of coniks-go, a re-implementation of CONIKS [1] in Golang: </span></div><div style="line-height:1.38;margin-top:0pt;margin-bottom:0pt" class="gmail_msg"><a href="https://github.com/coniks-sys/coniks-go/releases/tag/0.1.0" style="text-decoration:none" class="gmail_msg" target="_blank"><span style="font-size:14.666666666666666px;font-family:Arial;color:rgb(17,85,204);font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-alternates:normal;font-variant-east-asian:normal;text-decoration:underline;vertical-align:baseline" class="gmail_msg">https://github.com/coniks-sys/coniks-go/releases/tag/0.1.0</span></a></div><div dir="ltr" style="line-height:1.38;margin-top:0pt;margin-bottom:0pt" class="gmail_msg"><br class="gmail_msg"></div><div style="line-height:1.38;margin-top:0pt;margin-bottom:0pt" class="gmail_msg"><span style="font-size:14.666666666666666px;font-family:Arial;font-variant-ligatures:normal;font-variant-numeric:normal;font-variant-alternates:normal;font-variant-east-asian:normal;vertical-align:baseline" class="gmail_msg">This project started as a Google Summer of Code project in 2016 as a collaboration between the TorMessenger Project, Princeton University, and the EPFL with the goal of integrating CONIKS into Tor Messenger [1].
