Create the perfect custom blockchain for your enterprise

Parity knows blockchains. That’s why we’ve built Substrate, a technology that makes it quick and easy to build the perfect blockchain for your needs.

Create a blockchain with the right privacy level for your use case
Light- client- first design for mobile applications and IoT
Forkless upgrade path to keep networks together

Built on next-generation tech

Substrate builds upon the achievements from the major blockchain protocols, and uses the lessons learned to give developers the latest technology to build flexible blockchains.

Architected on industry-standard WebAssembly
Highly extensible Libp2p networking
Rust-based primary implementation for speed and reliability
Javascript secondary implementation for developability
Wasm WebAssembly interpreter, written in Rust

Substrate gives you possibilities

Not every blockchain is suitable for every network. With Substrate, you can mix and match features to suit your project's needs.

WebAssembly smart contracts
Multi-level permissioning
Encrypted transactions and state
Limiting to asynchronous calls optionality
Account-level locking
Governance tools and methods such as stakeholder referendums, approval voting, and qualified abstention biasing
