Substrate (Polkadot Development Framework)

Substrate, developed by Parity Technologies, is a blockchain integration platform and application development framework that plays a key role in achieving blockchain interoperability with Polkadot. Its primary function is to streamline the creation of dApps (decentralized applications) or independent blockchains that function within the Polkadot network. Substrate stands out for its versatility, offering a comprehensive blockchain design framework that supports development in multiple programming languages, allows for forkless upgradability, incorporates a light-client architecture, and provides a wide range of development tools. While Substrate is a powerful component of the Polkadot ecosystem, it’s worth noting that developers have the option to build blockchains on the Polkadot network without utilizing Substrate.
