Polygon POS: An EVM-Compatible Layer on Top of Ethereum

The idea of polygons is this kind of infinitely scalable layer on top of Ethereum made a lot of sense to me. And as I said, things just started clicking and everything happened organically. So Polygon POS chain is an EVM compatible chain that operates alongside in or in parallel with Etherum. It indeed has its own validator set, hence the name Polygon POSChain.
