Parity Substrate is a powerful tool that allows Edgeware developers to focus on improving their chain without worrying about infrastructure development. With Substrate, chains can be extended with modules written in Rust, compiled to Wasm, and linked into the client runtime. These modules can be voted into a chain by on-chain governance, and all clients will automatically download and run them in a safe sandboxed environment. This makes upgrading a chain much simpler and more accessible to a wide variety of developers, without the need for network or runtime level engineering changes.
