I've been on Lemmy for some time now and it's time for me to finally understand how Federation works. I have general idea and I have accounts on three federated instances, but I need some details.

Let Alpha, Beta, Gamma and Delta be four federated instances. I have an account on Alpha and create a post in a community on Beta. A persoson from Gamma comments on it and a person from Delta upvotes the post and the comment.

The question: On which instances are the post, the comment and the upvotes stored?

your votes are visible to all instances. it's easier to think about when you think of voting like favoriting in mastodon except lemmy doesn't send a notification

Yes, I discussed this in another thread. There could be ways to protect this info. But, it would mean totally changing (and agreeing with all other threadiverse apps) the way this is handled. Even then, I'm not sure you could prevent exploitation if the full info isn't sent. On kbin this info is visible anyway. You don't need any fake instance to do it.
