Welcome to Polygon

Polygon is a scaling solution for public blockchains. Polygon PoS supports all the existing Ethereum tooling along with faster and cheaper transactions.

Types of Interaction on Polygon

Query the blockchain

Most blockchain interactions involve reading its state.

Alchemy offers a reference guide on how to make basic requests to the blockchain. Check out their guide on how to query Polygon.

What is a Blockchain?

Simply put, Blockchain is a shared, immutable ledger for recording transactions, tracking assets and building trust. Head over to Blockchain Basics to read more.

What is a Sidechain?

Think of a Sidechain as a clone of a 'parent' blockchain, supporting transfer of assets to and from the main chain. It is simply an alternate to parent chain that creates a new blockchain with its own mechanism of creating blocks (consensus mechanism). Connecting a sidechain to a parent chain involves setting up a method of moving assets between the chains.

Validator and delegator roles

On the Polygon Network, you can be a validator or a delegator. See:


If your goal is to become a validator, it is essential that you understand the Polygon architecture.
