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
