What Is Polygon

Polygon is a Layer 2 scaling solution that achieves scale by utilizing sidechains for off-chain computation while ensuring asset security using the Plasma framework and a decentralized network of Proof-of-Stake (PoS) validators.

Polygon strives to solve the scalability and usability issues while not compromising on decentralization and leveraging the existing developer community and ecosystem. Polygon is an ​off-/sidechain scaling solution for existing platforms to provide scalability and superior user experience to DApps and user functionalities.

Key features & highlights

  • Scalability: Fast, low-cost and secure transactions on Polygon sidechains with finality achieved on mainchain and Ethereum as the first compatible Layer 1 basechain.
  • High throughput: Achieved up to 10,000 TPS on a single sidechain on internal testnet; Multiple chains to be added for horizontal scaling.
  • User experience: Smooth UX and developer abstraction from mainchain to Polygon chain; native mobile apps and SDK with WalletConnect support.
  • Security: Polygon chain operators are themselves stakers in the PoS system.
  • Public sidechains: Polygon sidechains are public in nature (vs. individual DApp chains), permissionless and capable of supporting multiple protocols.

The Polygon system was consciously architected to support arbitrary state transitions on Polygon sidechains, which are EVM-enabled.
