Parity Technologies announced today that the Substrate 1.0 Beta is out now, which seeks to assist in blockchain and decentralized application development. Substrate is an open-source technology stack that makes it easy to create a blockchain customized for a particular application.
Substrate is architected to be as generic as possible in order to give developers maximum technical freedom when designing their blockchain. It has a 100% abstract “execute block” function encoded in WebAssembly that can be targeted from any one of a number of languages, including C++ and Rust. The execute block function is hot-swappable, meaning developers can upgrade their chain’s logic without a hard fork.
The consensus is furthermore generalized. The API provided lets developers roll their own consensus mechanism and it can handle most consensus algorithms out there. Substrate 1.0 Beta provides a combined Aura/GRANDPA consensus, with more consensus algorithms to be provided in subsequent releases.
With Substrate, devs can easily configure their blockchain, but also take complete control over the code should they need to. This flexibility between ease and technical freedom is achieved through a modular design: Substrate is separated into Substrate Core, Substrate Runtime Module Library (SRML) and comes with a pre-assembled Substrate Node that is simple to configure.
