Is AltLayer Layer 2?

Could you elaborate on whether AltLayer qualifies as a Layer 2 solution? I've heard of various Layer 2 protocols that aim to enhance scalability and transaction throughput on blockchain networks, but I'm unsure if AltLayer specifically falls into this category. Could you provide some key characteristics or functionalities that AltLayer possesses to classify it as a Layer 2 solution, or are there specific technical differences that set it apart from traditional Layer 2 implementations? Your insights would be greatly appreciated.
