When you said protocol, I think you were referring to the “type” of website kbin is, correct? If so, yes you’re correct, it is a hybrid of both Lemmy and Mastodon. So both a link aggregator/discussion website, as well as a microblog.
Although, when people say “protocol” in the context of the Fediverse, they are almost always referring to the ActivityPub protocol which allows all these websites to interoperate with each other - they all use it, and that’s what allows the users/content to flow from one place to another. So in that sense, no, kbin is not using a different protocol from the others.
