Polkadot Runtime
Polkadot Runtime is the core execution environment for parachains and the Relay Chain in the Polkadot network, implemented as a WebAssembly (Wasm) module that defines the state transition logic and governance rules. It handles key functions like consensus, staking, governance, and cross-chain messaging (XCMP) through a modular, upgradable framework without requiring hard forks. This runtime enables developers to build custom blockchains (parachains) that can interoperate securely within the Polkadot ecosystem.
Developers should learn Polkadot Runtime when building interoperable, scalable blockchain applications that need to leverage shared security and cross-chain communication, such as DeFi protocols, NFT platforms, or enterprise solutions requiring modular governance. It's essential for creating parachains that can seamlessly integrate with other chains in the Polkadot network, offering benefits like on-chain upgradability and reduced development overhead compared to standalone blockchains.
