We am making this request to our bellowed Tor Project developers and relay operators to reconsider issue
https://gitlab.torproject.org/tpo/core/tor/-/issues/2667.
Tor over tor scenario is not recommended by Tor project but We are
forced to use such setup to hide our operations from the powerful
adversary which would in case we use bridge between our two tor path
most likely possible de-anonymize us and put our life in dangerous.
Tor
is making our work possible and helping collaborate without
restrictions, please let's reconsider this issue one more time. We are
running number of relay and we considered not applying latest update to
help us at least work with our own relay but adversary observes big part
of network and will most likely identify us when 70% of network start
dropping tor over tor connections.
Tor over tor scenario does not
amplify attack power within tor network, the strength of any request is
losing it's power right after first hop, but for many people it
provides necessary and much required privacy.
We
do highly sensitive work in research journalism across the globe and
only way we found so far not be de-anonymized was tor over tor scenario,
probably for reason that two circuits are dynamic and it's very hard
for adversary to track that down properly due to nature of tor network.
Understandable that you most of time support regular Tor Browser usage
and 3 hop circuits but believe us there are situations where our
scenario is really necessary.
We have
collected donations of around 21000 USD in XMR so far(we know it's not
much), which we can either donate to Tor project to help fix this issue
or otherwise fund relay operators to run not-up-to-date relays just to
help us operate under this powerful adversary. The second is worse
solution as it would make network more vulnerable, or at least allow
relay operators to enable or disable that option and don't make it
mandatory.
