Polygon PoS Overview

Polygon PoS (Proof-of-Stake) is a blockchain network that operates as a sidechain, a Layer 2 scaling solution for Ethereum. It aims to provide faster and cheaper transactions while leveraging the security of the Ethereum mainnet.

The technical details about Polygon PoS are available in the official documentation.

Originally launched as Matic Network in June 2020, Polygon PoS has undergone numerous upgrades since its inception. Initially designed to scale Ethereum through a sidechain, a new proposal on the Polygon forum suggests upgrading Polygon PoS into a zero-knowledge (ZK)-based validium on Ethereum. Polygon PoS will soon adopt the execution environment of Polygon zkEVM along with a dedicated data availability layer. This new architecture would be inherently interoperable with a broader network of ZK-powered Ethereum L2s via the AggLayer. Polygon PoS will continue to be the foundational infrastructure for a wide array of decentralized applications and services.
