# Welcome to the Wiki.
What I am noticing is that there is no notion of a Tox Improvement Proposal(TIP),
so ideas and vulnerabilities get forgotten in abandonned PRs in abandoned repos.
What I am noticing is that there is no notion of a Tox Improvement
Proposal(TIP), so ideas and vulnerabilities get forgotten in
abandonned PRs in abandoned repos, or ignored issues.
I suggested wiki.tox.chat as a place to identify and prioritize TIPs but maybe we can elaborate POCs here. I want to "argue" it out to get to the "best" proposal so work so work can get going on a trial version. developers who know the key exchange mechanisms can bring a lot of the existing codebase to bear on this problem, and resolve wrinkles in the concepts.

Tox relies on "bootstrap" nodes to be able to find your Friends. That
list of nodes is quite small, < 100, and you can find it in the file
often called DHTnodes.json. If a country like Iran can block those
nodes, they can block Tox. Whether Tox is encrypted makes no difference
in their ability to block.
Tox works well over [Tor](https://torproject.org/), which should help.
If they can't block Tor, then they can't block Tox over Tor. And Tor
is evolving stratagies to help defeat blocking, like
[snowflake](https://torproject.org/). As Tor evolves its resillience
strategies, Tox over Tor evolves with it. It is *much* harder to block
Tox over Tor than to block services like WhatsApp which relay on
centralized servers, unless the service runs a OnionV3 Tor service
that makes if accesible directly over Tor.
Everyone who wants to help the network be resilient to blocking should
run their clients like [toxic](https://github.com/JFreegman/toxic/)
with the ```-T, --tcp-relay``` if they are not using Tor. Choose a
random port number ```> 10000 < 65000``` for the port.
If you are not running over Tor and are on a stable connection, try it.
Every BSnode operator who wants to help the network be resilient in
places like Iran should run a Tor server that provides the node as an
onionV3 service; see [[ToxAndTorInChina]].
If you run a bootstrap node, you can run a Tor Ononv3 gateway to the
node by simply adding the following lines to your ```torrc```
configuration:
```
# Tox hidden service configuration.
HiddenServiceDir /var/lib/tor/tox-hsv3/
HiddenServicePort 3389 127.0.0.1:3389
HiddenServicePort 3389 127.0.0.1:33446
```
assuming your Tor lib directory os ```/var/lib/tor```. In that subdirectory
you will find a file named ```hostname``` which is the ```.onion``` name
of your node, the Tor equivalent of your ToxId.
