 # federation
 
+A big problem is a lack of clarity on what instances are blocked and why by various instances.
+This is a documentation and accessibility issue as I doubt most instances make neither.
+
+The other big problem is having central authorities.
+You can see this on the internet now with certificate authorities.
+If a CA is compromised, which they have and they will, then the trust is broken at the root and anything that inherited that trust needs to have it reestablished.
+I’m not eager to apply blockchain to something that is a governance issue.
+An alternative is notaries.
+
+Sharing inspiration for a design.

+
+The general idea is trusting more than one authority, polling them for a consensus on which instances are filtered/restricted. Many nodes would simply proxy their inherited filters but can change what node they would inherit trust from.
+
+Much like users pick an instance to join because of a theme or the moderation policies, instances could join a federation because of a grand moderation policy.
