Introducing Decentralized Identifiers (DIDs)

Decentralized Identifiers (DIDs) are a fundamental component of decentralized identity systems. A DID is a unique, globally resolvable identifier that is generated and managed by the identity owner. Unlike traditional identifiers, such as usernames or email addresses, DIDs are not issued by a central authority but are instead created and controlled by the user themselves.
In his original 1989 proposal for what would become the World Wide Web, Tim Berners-Lee outlined a vision of a “universal linked information system” where users would have control over their own data. He foresaw a decentralized architecture where information would be stored in “nodes” that users could link together through “links” in whatever way made sense to them.

Web1 Identifiers (1990s)

In the early days of the internet known as Web1: Digital identity was limited and decentralized People used anonymous usernames or email addresses to identify themselves There were no widespread standards or protocols for proving one’s identity online

Web2 Identifiers (2000s)

As the internet became more advanced in the Web2 era: Centralized identity providers emerged like Google, Facebook, Twitter Single sign-on allowed using one identity across multiple websites This made identity more convenient but gave control to a few big tech companies Privacy concerns emerged around tracking and data collection by identity providers

Web3 Identifiers (2010s-Present)

Web3 is ushering in a new phase of digital identity: Blockchain technology enables decentralized, user-controlled identity Decentralized identifiers (DIDs) give users more control of their data Verifiable credentials allow proving claims without oversharing personal info Self-sovereign identity (SSI) puts users in charge of their identities But standards are still emerging and adoption is in early stages

The Path Forward (2024-Beyond)

Digital identity has evolved from limited and decentralized, to convenient but centralized, to user-empowered but complex

The Technical Aspects of DIDs

A DID consists of three main components:
  • Scheme: The identifier for the DID method, such as “did”.
  • Method: The specific DID method used, such as “example”.
  • Method-Specific Identifier: A unique identifier within the context of the DID method.
Example DID: did:example:123456789abcdefghi

​
Decentralized Identity Methods

DID methods define the specific implementation details for creating, resolving, and managing DIDs on different distributed ledger technologies or decentralized systems. Each DID method has its own specification, which outlines the technical requirements and procedures for working with DIDs within that particular ecosystem.

Decentralized Identity Resolution

DID resolution is the process of retrieving the DID Document associated with a given DID. The resolution process involves querying the appropriate distributed ledger or decentralized storage system based on the DID method specified in the DID.
