Re: [tor-talk] Bitcoin over Tor isnât a good idea (Alex Biryukov / Ivan Pustogarov story)

[eric gisse <jowr.pi@xxxxxxxxx>]

To that end, I setup a bitcoin node that listens on the v4/v6 internet as
well as tor.

The hidden service address is dsyadrvivtt34s26.onion

Could some folks please test this for me and make sure it works for others?
I can see it is quite happily running on v4/v6 (and getting traffic) but
its' less obvious that it is working over tor.
