ElectrumX Onion host support

[java4tech]

Do you have any plans to support tor?

Yes - working on that next.

It's already possible to connect Sparrow to a Tor hidden service (.onion address) if you are running tor locally - just set the proxy details in the server preferences appropriately e.g. 127.0.0.1:9050.

By supporting tor, do you mean bundling the tor binaries with Sparrow so that it does not need a locally running tor instance?

I have tried to test it on Windows and got error on port 9050 (tried public nodes), I was getting connection refused but 9150 worked but still got the following error.

Could not connect:

Unsupported or unrecognized SSL message

This could also be a DNS Proxy issue

Yes, Netlayer also works with system installed tor since version 0.6

I was thinking about a use case where we can connect to any public node only for Sending Transaction, This can be used in a situation where user want's to use there server only for transaction update and don't want to reveal his node's IP while sending payment.
So In short:
We can keep or drop connection to our own node and connect to tor node>> Once transaction is broadcasted we can disconnect and connect back to our own node to check progress and balance. Attacker or analysis firms won't be able to map IP to our personal node.

Some suggestions:

1. You can use Netlayer project to support native tor. It is used by bisq project, So it is maintained. (I have tested it on windows and It works). We might be able to check if local instance is running first and if not then we can try to start native tor. Otherwise we'll end up with multiple tor instances and that might cause other issue (not Sure).
2. It'll be nice to have an option to disconnect node, user might want to do certain tasks while offline (Helpful if someone is using public node).

Implemented built in Tor support and released in v0.9.4 - closing this off.

The idea to have a connection to a separate node for broadcasting is an interesting one - perhaps something for a future release.
