Polygon
Web3 / layer2 solutions
Polygon is a multi-chain scaling solution and development platform that enhances Ethereum's capabilities by providing faster and cheaper transactions while maintaining full compatibility with Ethereum's ecosystem and smart contracts. Operating as a Layer 2 solution, Polygon uses several scaling technologies including the Plasma framework and Proof of Stake sidechains to batch transactions off-chain and periodically settle them to Ethereum mainnet. This approach allows applications to process thousands of transactions per second with transaction costs measured in fractions of cents, compared to Ethereum mainnet's variable fees. Polygon has become one of the most widely adopted scaling solutions, with thousands of decentralized applications (dApps) deployed across its ecosystem. Example: Aave, a leading lending protocol, deployed on Polygon to offer users the same lending and borrowing functionality as the Ethereum mainnet version but with transaction costs reduced from dollars to pennies. Why it matters for Layer 2 scaling: Polygon demonstrates that scaling solutions can achieve mass adoption by maintaining EVM compatibility while dramatically reducing costs, proving that users don't require a separate blockchain ecosystem if scaling happens transparently through Ethereum-compatible infrastructure.
