Substrate

Substrate is a modular framework for building blockchains, developed by Parity Technologies. It provides flexibility, allowing developers to create both independent blockchains and networks compatible with the Polkadot ecosystem. With its architecture, Substrate supports customizable consensus mechanisms, token economies, and integration with various cryptographic primitives. This framework is used to develop high-performance, scalable, and decentralized networks with upgradeability without hard forks.
