Is ordi a layer 1?

I'm quite interested in the technological intricacies of the blockchain industry. Could you please enlighten me on the concept of Ordi being labeled as a layer 1? I've heard various discussions about it, but I'm still a bit hazy on the specifics. Could you break it down for me? Is Ordi indeed considered a layer 1 in the blockchain architecture? If so, what are the distinguishing features that make it qualify as such? I'd really appreciate your insights into this matter.
