-------------------------+-------------------------------------------------
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.
