What is Polygon (POL)?

Polygon (POL), formerly MATIC, is a blockchain platform created to help Ethereum handle more activity without becoming slow or expensive. If you’ve used Ethereum before, you’ve likely noticed how fees rise and transactions slow down during busy periods. Polygon addresses this by running transactions on its own infrastructure and then finalizing them on Ethereum mainnet, which helps reduce congestion while keeping strong security. The polygon network is fully compatible with Ethereum, and it operates as a Layer 2 scaling solution, enabling faster and more cost-effective transactions. 

If you’re new to crypto, understanding what is a blockchain makes this clearer. A blockchain is a digital ledger shared across many computers where transactions are recorded permanently and transparently. Polygon builds on this concept by adding scalable layers that can process more transactions at a lower cost. POL is the native token that keeps the system running. You use it to pay transaction fees, stake to help secure the network, and take part in governance decisions. This combination has made Polygon a popular choice for DeFi platforms, NFTs, gaming, and other Web3 applications that need speed and affordability.

How Does Polygon Work?

Polygon works as a Layer 2 scaling solution that helps Ethereum process transactions faster and at a much lower cost, while staying fully compatible with Ethereum’s blockchain. Instead of competing with Ethereum, Polygon runs alongside it using a parallel system that handles activity more efficiently and then anchors results back to Ethereum for security.

Here’s how the Matic network functions:

• Parallel Blockchain. Polygon acts as an express lane for Ethereum transactions. You can transfer your assets from Ethereum to Polygon using the Polygon Bridge, interact with decentralized applications (dApps) on Polygon, and later move your assets back to Ethereum.
• Proof-of-Stake (PoS) Consensus. The network uses a proof-of-stake mechanism to secure its operations. Validators verify transactions and add them to the blockchain, earning rewards in MATIC tokens. You can also stake your MATIC tokens indirectly through trusted validators.
• Plasma Framework. With the Plasma framework, Polygon processes high volumes of transactions efficiently. This framework supports the execution of smart contracts and ensures scalability.
• Interoperability. Polygon is fully compatible with Ethereum, allowing you to build and deploy dApps seamlessly. Its infrastructure supports various use cases, including DeFi, gaming, and NFTs.
• Low Fees and Speed. Transactions on the Matic network are processed in under two seconds, with fees often costing a fraction of a cent. This makes it an attractive option for you as a user or developer.
