We can think of distributed identity as blockchain networks of people, not coins. Specifically, a 'decentralized identifier' (DID) is composed of a "Unique ID URI string and PKI metadata document format for describing the cryptographic keys and other fundamental PKI values linked to a unique, user-controlled, self-sovereign identifier in a target system (i.e. blockchain, distributed ledger)." This document defines the approved specification for credential schemas version 1.0 from the the Decentralized Identity Foundation. Use cases are mainly in "financial services, but can also be used in telecommunications, and any sector requiring identity verification for customer onboarding, transaction verification, and regulatory compliance, enabling streamlined and standardized data handling for 'Know Your Customer' (KYC) procedures."
