About paritytech/substrate

Substrate was a modular blockchain development platform created by Parity Technologies that enabled developers to build custom blockchains with composable components. Written in Rust, it provided a flexible framework for blockchain innovators to create nodes and clients without building from scratch, supporting various consensus mechanisms and runtime configurations.

The project served as the foundational technology for numerous blockchain projects in the Polkadot ecosystem and beyond. It abstracted away low-level blockchain implementation details while allowing developers to focus on their specific use cases, business logic, and innovations rather than reinventing core blockchain infrastructure.

The repository has since been consolidated into the Polkadot SDK, a unified monorepo that merged Substrate, Cumulus, and Polkadot codebases. Parity Technologies made this transition to streamline development, improve collaboration, and provide a more integrated platform for future blockchain development. Contributors with open pull requests were directed to resubmit their work in the new consolidated repository.
