Polygon (formerly known as the Matic Network) is a Layer-2 solution on the Ethereum network. It provides scalable, secure, and instant transactions using sidechains. Based on an adapted implementation of the Plasma framework, Polygon optimizes for asset security and employs a decentralized network of Proof-of-Stake (PoS) validators. Decentralized application (DApp) developers can leverage the Polygon network for its fast transaction speed and low transaction cost.
