Is Fantom Layer 1 or 2?

Could you please clarify for me? Is Fantom categorized as a Layer 1 blockchain or a Layer 2 solution? I've been trying to understand the nuances between the two, but I'm still a bit hazy on the details. Could you explain the differences between Layer 1 and Layer 2 in relation to Fantom specifically? And if Fantom is indeed a Layer 1, what are some of its key features or advantages that make it stand out in this category? Thank you for your assistance in clarifying this matter for me.
