 Validators are the key actor in maintaining the Polygon network. Validators run a full node, secure the network by staking MATIC to produce blocks, validate and participate in PoS consensus.
 
+Validators play a crucial role in maintaining the integrity and security of the Polygon PoS network. By running a full node, validators contribute to the network's infrastructure and help facilitate transactions. They secure the network by staking MATIC tokens, which enables them to produce blocks and participate in network consensus (PoS). This contributes to greater network security and enhances network decentralization making it more resilient against potential attacks.
+
+In return for their efforts, validators are rewarded with incentives, encouraging active participation and commitment to the network's stability and growth.

 !!!info
 
     There is limited space for accepting new validators. New validators can only join the active set when a currently active validator unbonds/is removed due to low performance.

-The Polygon Proof-of-Stake (PoS) network, originally launched as Matic Network in June 2020, has been upgraded a number of times since inception. Initially designed to scale Ethereum through a sidechain, a new discussion on the Polygon forum proposes upgrading Polygon PoS into a zero-knowledge (ZK)-based validium on Ethereum.
+The Polygon Proof-of-Stake (PoS) network is designed to address scalability challenges within the Ethereum ecosystem. It operates as an EVM-compatible Layer-2 (L2) scaling solution for Ethereum, enhancing its throughput while also significantly bringing down  gas costs, i.e., transaction fees.
 
-If passed, Polygon PoS would adopt the execution environment of Polygon zkEVM along with a dedicated data availability layer. The new architecture would be inherently interoperable, through an in-development interop-layer, with a broader network of ZK-powered Layer 2 (L2) chains on Ethereum.
