From PoS Sidechains to Rollups and SDK

Polygon’s technology offers a flexible stack of scaling solutions that include its popular PoS sidechain, zk-rollups, and optimistic rollups, enabling developers to select the best approach for their dApps. The PoS sidechain, often referred to as the Polygon blockchain, performs transaction processing and commits checkpoints to Ethereum for security. Polygon SDK further empowers developers to build standalone chains with customizable security parameters connected via PoS bridges. This modular design delivers scalability while maintaining decentralization and compatibility with Ethereum’s ecosystem.
