Previously known as the MATIC Network, Polygon is a framework for building interconnected blockchain networks to provide fast, secure, scalable, decentralized apps and marketplaces. Polygon is a layer-two (L2) scaling platform that leverages the security benefits of ETH as well as its smart contracts, but significantly improves the throughput (tx) capacity to 10,000 transactions per second making it more affordable, due to competitive gas fee prices.
