DID Document

A DID Document is a standardized JSON-LD object associated with a Decentralized Identifier that contains information necessary to interact with the identity. It typically includes cryptographic public keys, authentication methods, and service endpoints that describe how to communicate with the identity owner.

This document is published to a verifiable data registry, allowing others to look up the public keys needed to verify signatures or encrypt messages for the identity holder. It serves as the functional interface for the decentralized identity, acting as a public directory for secure interaction.

It ensures that the owner can prove control over their identifier at any time.
