Is Kaspa layer 1?

Excuse me, I'm a bit confused about Kaspa's technological architecture. Could you please clarify for me if Kaspa is indeed a layer 1 blockchain? I've been hearing a lot about its unique consensus mechanism and scalability solutions, but I'm still not entirely sure about its classification. Could you explain how Kaspa fits into the larger picture of blockchain technology, specifically whether it operates as a layer 1 or a different type of protocol? Thank you for your time and assistance.
