A sample Substrate runtime for a PoA blockchain that allows:

- Automatically remove authorities when they go offline, to recover block period.
- Add authorities again when they come back online.
The runtime uses the Substrate Validator Set pallet for the above functionalities.
To understand the concepts in detail, read this blog post - "Building a resilient PoA network with Substrate".
