Polygon PoS Network:

Ethereum's Internet of Blockchains Polygon 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.

Scale and Power

Polygon PoS is a layer 2 scaling solution that achieves unprecedented transaction speed and cost savings by utilizing side-chains for transaction processing. At the same time, PoS ensures asset security using the robust Plasma bridging framework and a decentralized network of Proof-of-Stake (PoS) validators.
