description Polygon Overview
Polygon encompasses blockchain infrastructure aimed at expanding the capacity of Ethereum-compatible applications. Its ecosystem includes Polygon PoS and tools for building connected chains, allowing developers to reuse familiar Ethereum development methods. Lower transaction costs and greater processing capacity are central goals, particularly for applications involving frequent interactions or large numbers of users. Gaming projects and businesses exploring blockchain systems can use Polygon infrastructure to build decentralized applications.
Its work includes zero-knowledge technology, which uses cryptographic proofs to verify computation. Security depends on the particular network and its design: Polygon PoS has its own validator system and does not simply inherit all of Ethereum's security. The name therefore describes an ecosystem rather than one uniform scaling architecture.
help Polygon FAQ
What token do I need to pay for transaction fees on the Polygon network?
To pay for gas fees on the Polygon network, users traditionally need MATIC tokens, though the ecosystem has been migrating toward the POL token as part of its 2.0 upgrade. The network is specifically designed to offer significantly lower gas fees than the Ethereum mainnet.
How does the Polygon ZK-EVM differ from the older Polygon PoS network?
The Polygon ZK-EVM utilizes zero-knowledge rollups to batch transactions and settle them directly on the Ethereum mainnet, offering enhanced security and equivalence for developers. This is a technological shift from the previous Proof-of-Stake sidechain, which relied on its own independent set of validators.
Can I bridge my ERC-20 tokens from Ethereum to Polygon?
Yes, you can transfer ERC-20 tokens across the chains using the official Polygon Bridge or various third-party cross-chain protocols. Once bridged, these tokens can be used seamlessly within Polygon's multi-chain ecosystem.
Which popular decentralized applications are built on Polygon?
Polygon hosts a massive ecosystem of decentralized applications, including major DeFi platforms like Aave and QuickSwap. It is also heavily utilized by NFT marketplaces like OpenSea to help users avoid Ethereum's high transaction costs.
