People Chain: How a Person Gets In and Uses the System

Overview

The People Chain is a system parachain in Polkadot that provides privacy-preserving proof-of-personhood. It uses Bandersnatch ring VRF cryptography to let individuals prove they are unique persons without revealing which person they are.

The core pallet lives at substrate/frame/people/ and the parachain runtime at cumulus/parachains/runtimes/people/.
