Is Kaspa a layer 1?

Could you please clarify whether Kaspa qualifies as a layer 1 blockchain? I've been reading about its unique consensus mechanism and scalability features, but I'm still not entirely sure if it fits the definition of a layer 1. Layer 1 blockchains are typically known for their foundational role in the crypto ecosystem, serving as the base layer for other applications and protocols to build upon. Given Kaspa's focus on scalability and security, I'm interested in understanding if it falls into this category. Could you help me understand this further?
