Polygon, formerly known as Matic Network, is a Layer 2 scaling solution for Ethereum that aims to improve scalability and usability. It offers a framework for building and connecting Ethereum-compatible blockchain networks, allowing developers to create dApps with faster transaction times and lower fees. Polygon achieves this through various technologies, including sidechains, Plasma, and a Proof-of-Stake (PoS) consensus mechanism. By providing a scalable infrastructure for Ethereum-based applications, Polygon enhances the user experience and facilitates the mass adoption of decentralized technologies.
