-------------------------+-------------------------------------------------
 Some initial research has been done on #31223 to sketch out a
 PoW/credential scheme that works for HS DoS defence.

 This ticket is to continue scheming and working on this design.

 Also see #33650 for an analysis on whether we can use v3 descriptors and
 INTRO cells as an end-to-end channel for passing parameters and tokens.

 Also see [https://lists.torproject.org/pipermail/tor-
 dev/2020-March/014198.html this thread] for an initial exploration of anon
 credential schemes.
