How does Federating work? (latte.isnot.coffee)

2 comments fedilink hide all child comments

Hi all, first time posting. I've tried googling a bit but its not totally clear to me. Say I have servers A, B, C, and D.

Can servers A and B federate, and then separately C and D federate?

If so, can A B and C be federated, but separately C and D be federated, so D is not recognized as federated for A?

If A, B, C, and D are federated, and it becomes apparent that D is a bad actor, how does D become defederated?

I feel like these kinds of situations are critical to ensure long term success. I really appreciate any answers anyone can provide!

From a philosophical perspective, it is pretty complex.

This is a a simple start on Lemmy's federation

-Allowlist: Explicitly list instances to connect to.

-BlockList: Explicitly list instances to not connect to. Federation is open to all other instances.

-Open: Federate with all potential instances.

Yes.

Yes.

If A, B, C, and D are federated, and it becomes apparent that D is a bad actor, how does D become defederated?

A, B, and C each individually decide whether they want to deferate with D. Maybe they all do, or maybe only some of them do. It's analogous to groups of people deciding who they want to be friends with.

At least that's my understanding.
