Polygon (formerly known as Matic Network) is a blockchain platform designed to address the scalability limitations of Ethereum. Launched in 2017 and rebranded to Polygon in 2021, the platform provides a framework for building and connecting Ethereum-compatible blockchain networks. Its flagship product is the Polygon PoS (Proof of Stake) chain, which operates as a sidechain to Ethereum and offers dramatically faster transaction speeds and lower fees.
Ethereum, while the most widely adopted smart contract platform, has historically struggled with high gas fees and slow transaction throughput during periods of peak demand. Polygon's PoS chain solves this by processing transactions on its own network of validators and periodically committing checkpoints to Ethereum for security.
Transactions on Polygon confirm in seconds, and gas fees are typically a tiny fraction of a cent. This makes Polygon suitable for a wide range of applications, from high-frequency DeFi trading and gaming to everyday payments and NFT creation.
The POL Token
The native token of the Polygon PoS chain is POL (previously MATIC, with a migration completed in 2024). POL serves multiple functions within the ecosystem. It is the gas token used to pay transaction fees on the Polygon PoS chain and also the staking token used by validators and delegators to participate in securing the network through Proof of Stake consensus.
The Polygon Ecosystem
Beyond the PoS chain, Polygon has expanded into a broader family of scaling solutions including Polygon zkEVM. The ecosystem hosts a large DeFi ecosystem with major protocols including Aave, Uniswap, Curve, and QuickSwap deployed on the PoS chain. PolygonScan serves as the central transparency tool for all of this on-chain activity.
