What is Substrate and materials to get started

Substrate first steps curated list of resources.

What is Substrate

Parity Substrate is a blockchain development framework with many cool features like upgradable blockchains, modular architecture, customizable block execution logic, and hot-swappable consensus. For an overview of the Substrate framework, watch this talk from Dr. Gavin Wood (Web3 Summit, October 2018). Substrate is a framework for building upgradable, modular and efficient blockchains. Substrate is an open-source library of Rust code that is maintained by Parity Technologies. Source code available on GitHub.
