Polygon blockchain is a layer-2 scaling solution for Ethereum, designed to improve transaction throughput and reduce gas fees. By using technologies like Plasma, zk-Rollups, and sidechains, Polygon enhances the speed and scalability of Ethereum-based applications, making it more suitable for high-demand decentralized applications (dApps). With its interoperability features, Polygon allows developers to create scalable and secure blockchain networks that connect multiple chains. This makes Polygon a valuable platform for building efficient decentralized finance (DeFi) applications, NFTs, and other blockchain solutions.
