What type of L2 is a Polygon?

Could you please clarify what you mean by "L2" in the context of Polygon? Are you referring to Layer 2 solutions in blockchain technology? If so, Polygon is a popular Layer 2 scaling solution for the Ethereum blockchain. It aims to improve the scalability, speed, and efficiency of transactions on the Ethereum network by handling a significant portion of the transaction load off the main Ethereum blockchain. Polygon achieves this by using a system of sidechains, which are parallel blockchains that operate alongside the main Ethereum blockchain. By using Polygon, developers can build and deploy decentralized applications (dApps) that can handle a higher volume of transactions with lower fees and faster confirmation times. Is this what you were asking about?
