Overview and motivation<br class=""><br class="">To address scaling concerns with the onion web, we want to be able to<br class="">spread the load of hidden services across multiple machines.<br class="">OnionBalance is a great stab at this, and it can currently give us 60x<br class="">the capacity by publishing 6 separate descriptors, each with 10<br class="">introduction points, but more is better. This proposal aims to address<br class="">hidden service scaling up to a point where we can handle millions of<br class="">concurrent connections.<br class=""><br class="">The basic idea involves splitting the 'introduce' from the<br class="">'rendezvous', in the tor implementation, and adding new events and<br class="">commands to the control specification to allow intercepting<br class="">introductions and transmitting them to different nodes, which will then<br class="">take care of the actual rendezvous.<br class="">…<br class=""></blockquote></blockquote><br class=""><blockquote type="cite" class="">In general, I’m concerned that we need to think through the<br class="">implementation of this proposal more carefully, because it will help us<br class="">decide whether it’s compatible with:<br class="">* Current Hidden Services<br class="">* Next-Generation Hidden Services<br class="">And perhaps make changes to any of these proposals to make them work<br class="">together.<br class=""></blockquote><br class="">Thoughts welcome!
