W3C DIDs
W3C Decentralised Identifiers (DIDs) are a new type of globally unique identifier designed to enable verifiable, decentralised digital identity. As a formal web standard published by the World Wide Web Consortium (W3C), the DID architecture is a foundational component for building a more secure and user-centric internet.
Unlike traditional identifiers such as email addresses or usernames, DIDs are not tied to any centralised registry or company. This means that individuals and organisations can create and control their own identifiers, giving them "self-sovereign" control over their digital identities. The core of the system is the DID Document, a JSON file that contains the cryptographic keys and service endpoints associated with a DID. This document is stored on a distributed ledger or other decentralised network, allowing for secure and verifiable interactions.
The Hedera Consensus Service (HCS) is used to create a tamper-proof and auditable log of all DID-related events, such as creation, updates, and revocation.
