Implementation

A handle is a hostname (e.g: alice.example.com) which the server may or may not be able to provide a Decentralized ID for. A handle is made up of a domain (e.g: example.com) and a username (e.g: alice). A provider (ProvidesDecentralizedIDs) is responsible for getting a Decentralized ID from a handle.
