+Filename: 147-prevoting-opinions.txt
+Title: Eliminate the need for v2 directories in generating v3 directories
+Version: $Revision$
+Last-Modified: $Date$
+Author: Nick Mathewson
+Created: 2-Jul-2008
+Status: Open
+
+Overview
+
+ We propose a new v3 vote document type to replace the role of v2
+ networkstatus information in generating v3 consensuses.
+
+Motivation
+
+ When authorities vote on which descriptors are to be listed in the
+ next consensus, it helps if they all know about the same descriptors
+ as one another. But a hostile, confused, or out-of-date server may
+ upload a descriptor to only some authorities. In the current v3
+ directory design, the authorities don't have a good way to tell one
+ another about the new descriptor until they exchange votes... but by
+ the time this happens, they are already committed to their votes,
+ and they can't add anybody they learn about from other authorities
+ until the next voting cycle. That's no good!
+
+ The current Tor implementation avoids this problem by having
+ authorities also look at v2 networkstatus documents, but we'd like
+ in the long term to eliminate these, once 0.1.2.x is obsolete.
+
+Design:
+
+ We add a new value for vote-status in v3 consensus documents in
+ addition to "consensus" and "vote": "opinion". Authorities generate
+ and sign an opinion document as if they were generating a vote,
+ except that they send it to one another earlier than they send
+ votes.
+
+ Authorities don't need to generate more than one opinion document
+ per voting interval, but may. They should send it to the other
+ authorities they know about, at the regular vote upload URL, before
+ the authorities begin voting, so that enough time remains for the
+ authorities to fetch new descriptors.
+
+ Upon receiving an opinion document, authorities scan it for any
+ descriptors that:
+ - They might accept.
+ - Are for routers they don't know about, or are published more
+ recently than any descriptor they have for that router.
+ Authorities then begin downloading such descriptors from authorities
+ that claim to have them.
+
+ Authorities MAY cache opinion documents, but don't need to.
