ok thanks . by linked i meant this fediverse thing. I was reading here on reddit

Here is the catch, users from each server can interact with one another. So users who created their account in lemmy.world can comment in the subs of lemmy.ml aka the other server.

Now, when it comes to the last point, this is only possible if the two servers admins agree to do so. This is called federation

So every lemmy instance is separate?

For instance, I’m on lemmy.world now, reading nba community. If those mods go nuclear and someone creates another nba community elsewhere, will I see those posts on lemmy.world?

edit: i get it now … it’s a different server with different community, but they can be “linked” and you can subscribe to communities from different servers from your own server and you can also comment on different servers too from your own little world

i have more questions though … how do all these decentralized servers find each other and share information between instances? is it blockchain based? or is there a central server somewhere orchestrating it all ?
