How Tor and the Onion Browser Work

Sites on the Tor network can't use standard domain names. Instead, they're referred to as pseudo-domain names that end in .onion. These domain names aren't managed by a central authority but are instead based on cryptographic keys.

These .onion sites are only accessible through the Tor Browser, which you can download for free from the Tor Project's website. The regular web browser that you're probably using to read this page isn't compatible with these addresses. You'll need to download the Tor Browser (also known as the Onion Browser) before clicking any of the links below.

Once you've downloaded and installed Tor, head to https://onionlinks.com to discover fresh v3 onion links.

It's also important to remember that links to darknet sites should be treated with caution. If an onion link goes down, don't panic and Google for other possibilities. If a site is marked as unavailable, the most likely explanation is that the darknet website you're attempting to access is temporarily down. When a darknet site goes down, have patience. It's best practice to begin with Dread if you can handle the captcha and look for news instead of giving up when a darknet site is down.

You can also search twitter for recently added onion links.

Can't Open v3 Onion Links?

If you can connect to one .onion address, you should be able to access all of them. The hidden service may be down or overburdened.

Are you certain that your connection is through Tor? This site can tell you https://check.torproject.org/

Do you have Tor Browser open? It's possible that your Internet connection is leaking. If you don't know how to set up your own environment, try using the official Tor Browser. 

Is everything onion sites? It's possible that you tried a few of the now-defunct ones. Try Facebook, which should always be accessible. https://www.facebookcorewwwi.onion/
