3. Connect to a Zcash hidden server
-----------------------------------
To test your set-up, you might want to try connecting via Tor to just a
a single Zcash hidden server.
Edit zcash.conf and comment out any nodes you might normally connect to.
#addnode=alphatestnet.z.cash
Launch zcashd as follows:
zcashd -onion=127.0.0.1:9050 -addnode=abc123.onion
Now use zcash-cli to verify there is only a single peer connection.
