Polygon PoS

POL CMC #62 in the snapshot

Polygon PoS is an Ethereum-connected smart-contract chain with its own validator consensus, distinct from Polygon-branded zero-knowledge rollups.

01 / THE PURPOSE

What is Polygon PoS for?

Polygon PoS supports EVM applications while maintaining a separate execution ledger. Ethereum hosts staking and checkpoint-related contracts, and bridge systems move representations of assets between the two environments.

02 / THE ARCHITECTURE

Three questions about the machinery.

How does it agree?

Consensus & security

Validators stake POL and participate in the Heimdall consensus layer. The current architecture uses Heimdall-v2 with CometBFT, while Bor produces execution blocks. Checkpoints commit information to Ethereum; they do not turn every Polygon transaction into an Ethereum-verified rollup execution proof.

Where do instructions run?

Execution model

Bor supplies Ethereum-compatible contract execution, allowing wallets and development tools to interact with applications on Polygon PoS. Contracts, balances and transaction histories remain chain-specific despite familiar addresses and interfaces.

What is the token for?

POL in the system

POL is the gas and staking token for Polygon PoS, replacing MATIC in those roles. A token’s branding or migration history does not establish which network a wallet balance occupies or whether a separate Polygon project uses the same security model.

03 / THE DESIGN CHOICES

What comes with the design?

Each architecture makes choices about security, performance, coordination, and who can participate.

Validator concentration and outages can affect operation even when Ethereum itself is functioning normally.
Checkpointing does not remove bridge-contract, application, upgrade or asset-backing risks; withdrawal paths have their own timing rules.

04 / IN PRACTICE

Follow one use.

Illustrative: a successful swap on Polygon PoS is a change to Polygon’s ledger. Returning the output asset to Ethereum requires a bridge process; seeing the same wallet address on both chains does not move the balance.
