+# Adding an IRC proof
+
+Let's add a decentralized IRC proof to your OpenPGP keys.
+
+[[toc]]
+
+### Add a property to your IRC taxonomy
+
+After logging in into the IRC server with your registered nickname, send the
+following message (make sure to replace FINGERPRINT):
+
+```
+/msg NickServ SET PROPERTY KEY openpgp4fpr:FINGERPRINT
+```
+
+To check whether successful, send (make sure to replace NICK):
+
+```
+/msg NickServ TAXONOMY NICK
+```
+
+To add more fingerprints, send:
+
+```
+/msg NickServ SET PROPERTY KEY2 openpgp4fpr:FINGERPRINT
+```
+
+### Update the PGP key
+
+First, edit the key (make sure to replace FINGERPRINT):
+
+```
+gpg --edit-key FINGERPRINT
+```
+
+Add a new notation:
+
+```
+notation
+```
+
+Enter the notation (make sure to replace IRC_SERVER and NICK):
+
+```
+proof@metacode.biz=irc://IRC_SERVER/NICK
+```
+
+So, for user `foo` on the freenode server, this would be:
+
+```
+proof@metacode.biz=irc://chat.freenode.net/foo
+```
+
+Save the key:
+
+```
+save
+```
+
+Upload the key to WKD or use the following command to upload the key to
+[keys.openpgp.org](https://keys.openpgp.org) (make sure to replace FINGERPRINT):
+
+```
+gpg --keyserver hkps://keys.openpgp.org --send-keys FINGERPRINT
+```
+
+And you're done! Reload your profile page, it should now show an IRC account.

+# Adding a Matrix proof
+
+Let's add a decentralized Matrix proof to your OpenPGP keys.
+
+[[toc]]
+
+### Sending a proof message
+
+After logging in into Matrix, join the
+[#doipver:matrix.org](https://matrix.to/#/#doipver:matrix.org) room and send the
+following message (make sure to replace FINGERPRINT)
+
+```
+[Verifying my OpenPGP key: openpgp4fpr:FINGERPRINT]
+```
+
+Click on "View Source" for that message, you should now see the value for
+`room_id` and `event_id`.
+
+The value for `room_id` should be `!dBfQZxCoGVmSTujfiv:matrix.org`. The value
+for `event_id` is unique to your message.
+
+If your Matrix client does not support "View Source", choose "Share" or
+"Permalink". The URL obtained should look like this:
+
+```
+https://matrix.to/#/ROOM_ID/EVENT_ID?via=...
+```
+
+### Update the PGP key
+
+First, edit the key (make sure to replace FINGERPRINT):
+
+```
+gpg --edit-key FINGERPRINT
+```
+
+Add a new notation:
+
+```
+notation
+```
+
+Enter the notation (make sure to replace USER_ID, ROOM_ID, EVENT_ID):
+
+```
+proof@metacode.biz=matrix:u/USER_ID?org.keyoxide.r=ROOM_ID&org.keyoxide.e=EVENT_ID
+```
+
+So, for user `@foo:matrix.org`, this would be:
+
+```
+proof@metacode.biz=matrix:u/@foo:matrix.org?org.keyoxide.r=!dBfQZxCoGVmSTujfiv:matrix.org&org.keyoxide.e=$3dVX1nv3lmwnKxc0mgto_Sf-REVr45Z6G7LWLWal10w
+```
+
+Save the key:
+
+```
+save
+```
+
+Upload the key to WKD or use the following command to upload the key to
+[keys.openpgp.org](https://keys.openpgp.org) (make sure to replace FINGERPRINT):
+
+```
+gpg --keyserver hkps://keys.openpgp.org --send-keys FINGERPRINT
+```
+
+And you're done! Reload your profile page, it should now show a Matrix account.
