Polygon (Previously MATIC network) is a protocol and a framework for building and connecting Ethereum-compatible blockchain networks. Aggregating scalable solutions on Ethereum supporting a multi-chain Ethereum ecosystem.
"Polygon combines the best of Ethereum and sovereign blockchains into a full-fledged multi-chain system. Polygon solves pain points associated with Blockchains, like high gas fees and slow speeds, without sacrificing on security. This multi-chain system is akin to other ones such as Polkadot, Cosmos, Avalanche etc, but with at least three major upsides:
It is able to fully benefit from Ethereum’s network effects
It is inherently more secure
It is more open and powerful"
