 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. If approved, Polygon PoS would 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 foundational infrastructure for a wide array of decentralized applications and services. More details about the overarching vision of a unified ecosystem of L2s on Ethereum can be found in [the Learn space](../learn/index.md).
