Is ocean protocol layer 2?

I've been reading a lot about the Ocean Protocol recently, and it seems to be making quite a splash in the decentralized data economy. However, I'm a bit confused about its technical architecture. Could you clarify for me if Ocean Protocol is indeed a layer 2 solution? I've heard about layer 2 technologies being used to enhance scalability and reduce transaction costs on blockchains, but I'm not entirely sure if that applies to Ocean Protocol. Your insights would be greatly appreciated!
