Polygon is widely considered to be a “layer 2” blockchain, meaning it is built alongside Ethereum’s blockchain to help facilitate faster transactions, and typically with lower gas fees. Users can bridge their ETH to Polygon’s blockchain, and use many of the same dapps that exist on ETH. If you stake your $MATIC, your tokens are pooled together with other tokens to help maintain the reliability and decentralization of the network.
