Polkadot Runtime Environment
The Polkadot Runtime Environment (PRE) is a framework for building and deploying blockchain runtimes, specifically designed for the Polkadot ecosystem. It provides a standardized environment where developers can create custom blockchains (parachains) that can interoperate with the Polkadot network and other parachains. The PRE leverages WebAssembly (Wasm) for runtime execution, enabling secure, upgradable, and efficient blockchain logic.
Developers should learn the Polkadot Runtime Environment when building interoperable blockchains that need to connect to the Polkadot network, as it simplifies parachain development with tools like Substrate. It's essential for projects requiring cross-chain communication, shared security from Polkadot's relay chain, and scalability through parallel processing. Use cases include decentralized finance (DeFi) applications, supply chain tracking, and identity management systems that benefit from blockchain interoperability.
