About Polygon PoS

Polygon PoS operates as a Proof-of-Stake sidechain, using a Plasma framework that runs parallel to the Ethereum mainnet. This architecture allows high throughput and low fees by processing transactions off-chain before committing finalized state to Ethereum. Validators stake POL tokens to participate in consensus and secure the sidechain.

About Polygon zkEVM

The broader Polygon ecosystem, by contrast, encompasses ZK-powered Layer 2 solutions such as Polygon zkEVM. These solutions use ZK-rollup architecture that inherits Ethereum's L1 security directly, submitting validity proofs on-chain instead of relying on an independent validator set.


Plasma Framework

Polygon PoS uses Plasma checkpointing to periodically submit state roots to Ethereum mainnet.

Validator Set

Around 100 PoS validators stake POL tokens to secure the sidechain and produce blocks deterministically.

ZK-Rollup Layer 2

Polygon zkEVM uses ZK-rollup architecture, posting validity proofs to Ethereum for trustless security.

Validium Mode

Polygon PoS is transitioning to a zkEVM Validium, combining high throughput with ZK proof security.
