All zcash (named) addnode=.onion project nodes have been upgraded to the latest release;

Zcash 1.0.9
Tor 0.2.9.11 or 0.3.0.8

"Source code for a new Tor release (0.3.0.8) is now available on the
website. Among other things, it fixes two issues in earlier versions
of the hidden service code that would allow an attacker to cause a
hidden service to exit with an assertion failure."

@xyZcash thank you for your work!

I'm new to zcash and started a couple of days ago to run my node.
To run everything through tor I had to add a few options to my zcash.conf

onlynet=onion
dnsseed=0

I was wondering if I add all your onion urls to my config, do I still need to use dnsseed?
As it will connect to the 'normal' internet.


#28

I should probably point out here that these configurations were originally designed for Zcash node operators to run 'Dual Stack' servers over Tor (in the main), allowing for Tor and clearnet connectivity - the configurations were then expanded upon per use case and for Client (only) use.

You are correct in adding dnsseed=0 for optimal privacy for Tor 1 and Zcash 1 - Proxified Zcash (example) and I will clarify settings in the original post. For 'Dual Stack' servers this option should be left at the default value.

" -dnsseed - Query for peer addresses via DNS lookup, if low on addresses (default: 1 unless -connect/-noconnect) "

DNS leaks with Tor are not as much as an issue as they once were. Although they do remain an issue, more so with windows.

...

Using onlynet=onion will enforce using only the specified addnode=.onion addresses in your zcash.conf . Thus, if said services are ever 'offline' then you might have connectivity issues.

Whilst only enabling connectivity with .onion addresses is the most private way to run Zcash on Tor (because the traffic never exits from the Tor network), it is perhaps a good idea to allow .exit connections from Tor .exit nodes to reach other clearnet Zcash nodes. Simply having diverse connectivity can also be good for privacy and the Zcash network as a whole.

" -onlynet= - Only connect to nodes in network (ipv4, ipv6 or onion) "

...

Thank you for highlighting these additions!

This is a work in progress, without a 'one size fits all' solution and we certainly require some much more organized documentation.

It is also worth noting that fewer connections are considered to be better for privacy and anonymity than more connections, in terms of the network effect.

Satoshi thought that having 8 connections was 'optimal' for Bitcoin P2P (in terms of the network), broadcasting transactions and user privacy etc,. Setting maxconnections= 6 (or even to 4) in your zcash.conf might be advisable for clients who are seeking increased anonymity, for example.
