Existing Tor Guard Selection Algorithm

  • ALL_GUARD_LIST = guard information from latest consensus
  • GUARD_LIST = guards persisted to our state file
  • DIRECTORY_GUARD = if we select guards with the V2Dir flag. Guards with the V2Dir Flag can be used as entry guards for both fetching information from directories as well as for standard entry guards.

ON_BOOTSTRAP (no existing guards)

  1. RECEIVE_NEW_CONSENSUS
  2. From listed guards in ALL_GUARD_LIST with DIRECTORY_GUARD=true:
  3. 3 times do (default guard value on startup):
