Polygon

Polygon (formerly known as Matic Network) is a Layer 2 scaling solution for Ethereum. It aims to address some of the scalability and usability issues faced by the Ethereum network, such as high transaction fees and slow confirmation times.

Polygon provides a framework for building and connecting Ethereum-compatible blockchain networks, which are called “sidechains” or “commit chains.” These sidechains run in parallel to the Ethereum mainchain, allowing for faster and cheaper transactions while still maintaining interoperability with the Ethereum network.
